Abstract
OBJECTIVE Esketamine (Vesierra) is a molecule, used alone or in combination, to induce and maintain general anaesthesia and to relieve pain in emergency medicine. The aim of this study is to evaluate the long-term physicochemical stability of a 1 mg/mL solution of esketamine diluted in 0.9% sodium chloride (NaCl) and stored in polypropylene syringes at 5±3°C during 65 days (64+1 day at 22±3°C) and 72 hours at 22±3°C (room temperature), in order to centralise preparation under aseptic conditions in hospital pharmacy. METHODS Ten syringes were prepared under aseptic conditions. Five syringes were stored at 22±3°C for 3 days, and the five others were stored at 5±3°C for 64 days (+ 1 day at room temperature). The stability was periodically investigated. Particle appearance or colour changes were checked by visual inspection. A research of crystals was performed under the microscope. pH was followed to assess its stability. The turbidity of the solutions was estimated by a measure of optical densities at 350, 410 and 550 nm. The molecule concentrations were measured by ultra-high performance liquid chromatography (UHPLC) coupled with a photodiode array detection (PDA), using a newly developed method. RESULTS Based on microscopic examination, no crystals were observed, during the observation period. pH and absorbances at 350, 410 and 550 nm were also stable. Macroscopically, there was no change in colour and appearance of opacity, turbidity or precipitation. Statistical analysis indicates that 1 mg/mL esketamine solutions were chemically stable under these conditions, given that less than 5% of the solutions have lost more than 10% of their initial content during the study based on the prediction interval. CONCLUSIONS One mg/mL solutions of esketamine hydrochloride are physically and chemically stable after production, for at least 72 hours at 22±3°C and 64 days at 5±3°C (+ 1 day at room temperature).

[PMID: 38636881 DOI: 10.1016/j.ejpb.2024.114295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 04/01/2024] [Accepted: 04/15/2024] [Indexed: 04/20/2024]
Abstract
Postproduction handling of drug products during preparation or clinical use may affect the structure and efficacy of the drug and perhaps remain unnoticed. Since chemical modifications can impact the product's structure, stability, and biological activity, this study investigates the impact of elevated temperature and subtle shift in pH on the drug product post-dilution in saline. The mAb sample diluted in saline for administration was stressed at elevated temperature and slightly acidic pH condition. Extended stability studies were performed and monitored for size and charge heterogeneity. Size heterogeneity shows no significant changes, whereas charge heterogeneity shows an increase in basic variants and a reduction in main species. Further, basic variants were isolated and characterized to identify the type and site of chemical modification. Intact mass analysis and peptide mapping identify that the basic variants were attributed mainly to the isomerization of HC Asp102 into iso-Asp or its succinimide intermediate. Four basic variants were found to exhibit similar structural properties as the main and control samples. However, basic variants showed reduced binding affinity to HER2 receptor, while there was no significant difference in FcRn binding. The results indicate that modification in the HC Asp102, which is present in the CDR, affects antigen binding and thus can influence the potency of the drug product. Hence, with the conventional stability studies required to license the drug product, including in-use or extended stability studies to mimic the postproduction handling would be desirable.

Physicochemical stability of bortezomib solutions for subcutaneous administration. Sci Rep 2024; 14:8975. [PMID: 38637597 PMCID: PMC11026495 DOI: 10.1038/s41598-024-58473-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Accepted: 03/29/2024] [Indexed: 04/20/2024] Open
Abstract
For the majority of cytotoxic drug preparations, such as bortezomib, the unit dose information is not available. In addition, there is a lack of information on the physicochemical stability of the pharmaceutical preparation after opening; this information is crucial for its administration to patients in successive visits, and the per-patient cost can be affected. The purpose of our proposed physicochemical stability study is to determine the shelf life of the reconstituted liquid product under refrigeration and clinical practice conditions. This evaluation was extended to both vials and ready-to-use syringes prefilled with the contents of the open vial. The stability test design includes the specified storage conditions and the critical physicochemical parameters of reconstituted injectable bortezomib. Furthermore, this approach includes the determination of impurities, the monitoring of the purity of the mean peak using a photodiode array, the control of the mass balance, the monitoring of subvisible particles using a laser diffraction analyser, and the setting of stability specifications. For the chemical stability study, the amount of bortezomib and its degradation products were determined using a stability-indicating HPLC method. The physical inspection of the samples was performed throughout the stability study, and their pH values were also monitored. Bortezomib (2.5 mg/mL) in 0.9% sodium chloride remained stable for 7 days when stored in both polypropylene syringes and vials at 5 ± 3 °C (refrigeration) and shielded from light. Additionally, it exhibits stability for 24 h under storage conditions simulating clinical use (20-30 °C and protected from light). The proposed protocol provides the stability in the vials once reconstituted and in prefilled refrigerated syringes; this protocol can be used to reduce waste and increase cost savings.

Abstract
INTRODUCTION Despite the advantages of dose banding (DB) and numerous plans to adopt this practice, uptake of DB is still poor. As opinions of healthcare professionals were deemed essential in DB's acceptance, this study surveyed key stakeholders to determine the acceptance, facilitators, and barriers of DB in chemotherapy to improve its implementation. METHODS A cross-sectional study at the National Cancer Centre Singapore, involving physicians, nurses, and pharmacy staff, was conducted in February 2022. The Theory of Planned Behaviour was adapted to design a survey questionnaire to obtain the acceptance, facilitators, and barriers of DB. Additional questions on maximum acceptable dose variance and essential criteria for selecting drugs for DB were included. RESULTS A total of 93 participants responded, with a mean 9.75 ± 7.37 years of clinical experience. Less than half have heard of DB while few had prior experience. Drug cost was the top selection criteria for DB, followed by toxicity, therapeutic index, frequency of use and drug wastage. Acceptance rate of DB was 41.9%, with majority agreeing to use DB in various drugs but to determine patient suitability before usage. Being greatly affected by subjective norms, having a positive outlook for DB's impacts, and no effect on toxicity significantly influenced acceptance. CONCLUSION Prior to implementing DB at the institutional level, educational training addressing concerns over toxicity, and providing technological support can help improve acceptance. Future studies can involve patients' perspectives and more institutions for greater diversity in opinions.

Abstract
OBJECTIVES Pevonedistat is a new cytotoxic used in association with azacitidine for the treatment of acute myeloid leukaemia and high-risk myelodysplastic syndromes. The manufacturer indicates an 18-hour stability after dilution in dextrose 5% or 0.9% sodium chloride (0.9% NaCl) at 2-8°C. No information is given for re-using vials of pevonedistat.Our objectives were to study the physico-chemical stability of 50 and 200 µg/mL pevonedistat diluted in 0.9% NaCl, in glass tubes, 100 µg/mL in 0.9% NaCl in polyolefin infusion bags, and 10 mg/mL partially used vials with a Spike. All preparations were stored at 2-8°C, protected from light. MATERIALS AND METHODS Due to the limited quantity of pevonedistat available for this study, we prepared test solutions at 50 and 200 µg/mL in glass tubes in a small volume of 20 mL. Inorder to verify the absence of a sorption phenomenon of the molecule onto polyolefin, we prepared two infusion bags at 100 µg/mL. We tested concentrated solution at 10 mg/mL. At each analysis time, we tested three samples of each condition by high performance liquid chromatography (HPLC) coupled with a photodiode array detector. Physical stability was evaluated by a visual and sub-visual inspection. We measured pH at each analysis time. RESULTS Diluted solutions at 50 and 200 µg/mL in tubes and at 100 mg/mL in infusion bags retained more than 95% of the initial concentration for 14 days, the concentrated solution at 10 mg/mL did so for 7 days. No physical changes were detected visually or sub-visually. We found that pH values remained stable. CONCLUSION All diluted solutions remained physically and chemically stable for 14 days, the concentrated solution did so for 7 days. No interactions between the polyolefin bag and pevonedistat were demonstrated. This new data allows re-using the concentrated solution of pevonedistat in a commercial glass vial with a Spike, and storing a preparation in case of non-administration.

Abstract
OBJECTIVE The aim of this study was to investigate the physicochemical stability of morphine-bupivacaine-ziconotide mixtures used in intrathecal analgesia in polypropylene syringes and intrathecal pumps. MATERIALS AND METHODS The stability study method was conceived according to International Council for Harmonisation guidelines. For propylene syringes, six different mixtures of morphine-bupivacaine and ziconotide were assessed over seven days. Two storage temperatures were tested (5 °C ± 3 °C and 25 °C ± 2 °C). For implantable pumps, nine different mixtures were assessed over 60 days and stored at 37 °C. Assays were performed using ultrahigh-pressure liquid chromatography. Turbidity and pH also were measured throughout the study. RESULTS Results confirmed excellent physicochemical stability for morphine and bupivacaine in the study for all conditions investigated (pumps at 37 °C, polypropylene syringes at 5 °C ± 3 °C and 25 °C ± 2 °C). Concerning ziconotide, after seven days, our study showed that every 95% confidence interval calculated had lower bounds >90% for all mixtures stored in polypropylene syringes. In implantable pumps, a decrease of the concentration was observed in all the mixtures studied. Moreover, the appearance of a degradation product confirmed the ziconotide degradation. CONCLUSION All results are in favor with a physicochemical stable preparation for six mixture profiles when stored in polypropylene syringes at 5 °C ± 3 °C and 25 °C ± 2 °C. For mixtures stored in implantable pumps, the efficacy should decrease over time owing to the degradation of ziconotide. A trade-off between high morphine concentration and increased refill interval will need to be found by clinicians.

Abstract
INTRODUCTION Intravenous vedolizumab is a widely used monoclonal antibody for outpatients with inflammatory bowel disease. Drug preparation is performed on the day of administration, but is time consuming, causing unnecessary in-hospital patient delay and inefficient logistics for preparation and distribution. Storage of vedolizumab ready-to-administer infusions and distribution via pneumatic air tubes could streamline logistics in the outpatient setting. The aim of this study was to test the shelf life and stability of ready-to-administer intravenous infusion bags containing vedolizumab. METHODS For assessing in-use shelf life, the reconstituted product (300 mg fixed dose) was diluted to a concentration of 1.2 mg/mL in 0.9% NaCl under aseptic conditions, and stored in polyolefin infusion bags at 2-8°C prior to analysis. On replicate samples, we measured concentration, physical and chemical stability using sodium dodecyl sulphate polyacrylamide gel electrophoresis, size exclusion chromatography, and multi-angle laser light scattering, as well as biological activity using a biolayer interferometry assay to study target engagement, and endotoxin content to assess microbiological stability. Stability of ready-to-use vedolizumab was assessed also after transportation via pneumatic tube system. Samples were taken at different time points over an observation period of 30 days on four replicate samples. RESULTS For all parameters assessed, the ready-to-use solution of vedolizumab remained stable over a period of at least 30 days. There were no signs of protein aggregation, chemical instability, or loss of binding of the antibody to the α4β7 integrin target. There was no increase in endotoxin concentration over time. No significant difference was seen in antibody structural stability and protein aggregation between samples before and after transportation via pneumatic tube system. CONCLUSION When prepared under aseptic conditions, dissolved ready-to-administer vedolizumab infusion bags can be stored long term at 2-8°C and transported via pneumatic air tube, without observable loss of antibody stability or binding activity.

Abstract
BACKGROUND Chemotherapy doses are usually prescribed on the basis of body surface area but dose banding is emerging as an efficient alternative. Dose banding presents the possibility of in-advance preparation in a Centralized Intravenous Admixture Service. AIM OF THE STUDY To evaluate the long-term stability of 5-fluorouracil at banded doses (700 mg and 800 mg) in polyolefin bags. MATERIALS AND METHODS Ten polyolefin bags were prepared under aseptic conditions and stored at 23 ± 2°C for 24 days. Five of them were composed of 14 mL 5-fluorocuracil (700 g) in 100 mL 0.9% sodium chloride solution and the five other of 16 mL 5-fluorouracil (800 mg) in 100 mL 0.9% sodium chloride solution. At defined times, physical stability parameters were assessed: optical densities, pH measurements, visual and microscopical inspections. Solutions concentrations were measured using high-performance liquid chromatography coupled with a photodiode array detector. RESULTS No change was observed on pH and optical density measurements during the study period. Visual and microscopical inspections remained free of colour change, precipitate, microagregate or crystal. The concentrations of 5-Fluorouracil in 800 mg bags remained stable for 24 days while the concentration in 700 mg bags showed a stability of at least 17 days. CONCLUSION Five-fluorouracil at banded doses of 700 and 800 mg in polyolefin bags is physicochemically stable for at least 17 days at 23 ± 2°C. These results support the possibility of in advance centralised preparation.

Abstract
OBJECTIVE In multiple myeloma patients, daratumumab is preferably injected subcutaneously. The summary of product characteristics of daratumumab subcutaneous injection solution specifies physicochemical stability for the prepared syringe for 24 hours at 2-8°C protected from light, and another 12 hours at room temperature (15-25°C) in ambient light conditions. The aim of this study was to determine the in-use stability of ready-to-administer daratumumab subcutaneous injection solution in different types of syringe and different conditions over a 28-day period. METHODS Daratumumab subcutaneous (DARZALEX 1800 mg) injection solution was withdrawn into disposable three-piece Luer-Lock syringes (20 mL, 50 mL), capped, and stored light protected at 2-8°C or at room temperature (22±2°C) over a maximum period of 28 days. Samples were taken immediately after preparation (day 0) and after 2, 7, 14, 21, and 28 days. Physicochemical stability was determined by ion-exchange high-performance liquid chromatography (IE-HPLC) and size-exclusion high-performance liquid chromatography (SE-HPLC) with ultraviolet detection, pH measurement and visual inspection for particles or colour changes. RESULTS In the IE-HPLC assay, peak areas and peak-to-peak area ratios remained unchanged over the whole study period, and showed no additional peaks of degraded daratumumab charge variants. In the SE-HPLC assay, neither a formation of aggregates nor of fragments was detected. Daratumumab monomer concentrations exceeded 95% of the initially measured concentrations over the entire test period. pH values remained constant. Test solutions remained clear, and no colour changes or visible particles were detected. All results were independent of storage conditions. CONCLUSION Daratumumab subcutaneous injection solution proved to be physicochemically stable in capped three-piece plastic syringes for at least 28 days when stored light protected at 2-8°C or at room temperature (22±2°C). For microbiological reasons aseptic preparation and refrigerated storage are recommended. In-use stability of ready-to-administer daratumumab subcutaneous syringes prepared under appropriate aseptic conditions is given for 28 days.

Abstract
BACKGROUND Preparation of injectable anticancer drugs in hospital pharmacies is a high-risk activity that requires a proper risk assessment (RA) and quality assurance system (QAS) to ensure both a decrease in risk associated with chemotherapy compounding and high quality of the final product, especially in terms of its microbiological stability. METHODS At the centralized compounding unit (UFA) of the Italian Hospital IOV-IRCCS, a quick and deductive method was applied to evaluate the "added value" provided by each prescribed preparation, and its RA was calculated applying a formula that integrates different pharmacological, technological and organizational aspects. According to specific RA range values, the preparations were divided into different risk levels, in order to determine the QAS to be adopted, according to the Italian Ministry of Health guidelines, whose adherence was meticulously evaluated through a specific self-assessment procedure. A review of the scientific literature was carried out to integrate the risk-based predictive extended stability (RBPES) of drugs with data concerning their physiochemical and biological stability. RESULTS Based on the self-assessment comprising all microbiological validations of the working area, personnel and products, the microbiological risk level within the IOV-IRCCS' UFA was defined through the creation of a transcoding matrix, conferring a microbiological stability to preparations and vial leftovers of a maximum of 7 days. The calculated RBPES were successfully integrated with stability data from the literature, leading to the drafting of a stability table of drugs and preparations in use in our UFA. CONCLUSIONS Our methods allowed us to perform an in-depth analysis of the highly specific and technical process of anticancer drug compounding in our UFA, ensuring a certain grade of quality and safety to preparations, especially in terms of microbiological stability. The resulting RBPES table represents an invaluable tool with positive repercussions at organizational and economic levels.

Physicochemical stability of cefiderocol, a novel siderophore cephalosporin, in syringes at 62.5 mg/mL for continuous administration in intensive care units. Eur J Hosp Pharm 2023; 30:e29-e34. [PMID: 34407976 PMCID: PMC10086710 DOI: 10.1136/ejhpharm-2021-002935] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Accepted: 07/19/2021] [Indexed: 11/03/2022] Open
Abstract
INTRODUCTION Cefiderocol is a new siderophore time-dependent antibiotic of last resort. The manufacturer reports a stability of 6 hours for the infusion solution diluted in normal saline (NS) or dextrose 5% in water (D5W) for a concentration between 7.5 and 20 mg/mL. Optimising its effectiveness by continuous infusion is crucial. The aim of this work was to study the physicochemical stability of cefiderocol diluted in NS or D5W in polypropylene syringes for 48 hours at a concentration of 62.5 mg/mL stored at room temperature, protected or not from light. MATERIALS AND METHODS Three preparations for each condition were performed. At each time of the analysis, one sample for each preparation was analysed in triplicate by a validated high performance liquid chromatography method coupled to a photodiode array detector at 260 nm. Particle contamination, absorbance measurement, visual inspection and pH measurement were assessed. The limit of stability was set at 90% of the initial concentration, without physical modification. RESULTS The linearity was validated with an R² of 0.9999. The coefficients of variation for repeatability and intermediate precision were less than 2%. In NS and D5W, cefiderocol retained more than 90% of the initial concentration after 12 hours in syringes, exposed or not to light. Two degradation products (nos 2 and 11, observed during forced degradation) were detected during the stability study. The absorbance at 410 nm increased progressively, regardless of the storage conditions. The particulate contamination test met the specifications of the container. pH values were all between 5.22 and 5.32. No visual changes were detected. CONCLUSION In polypropylene syringes, cefiderocol 62.5 mg/mL (3 g in 48 mL) diluted in NS or D5W was stable for 12 hours at room temperature. These new data allow the use of cefiderocol in continuous infusion.

Abstract
Abstract
Objectives
Bevacizumab was first marketed in 2005. Since then, its stability has been extensively studied. The arrival of numerous biosimilars on the market has called into question these stabilities and organisation within reconstitution units. To study the stability of the Bevacizumab biosimilar Alymsys® marketed by Zentiva laboratory in ready-to-use vials at a concentration of 25 mg/mL and following dilution to obtain final concentrations of 1.4 and 16.5 mg/mL and storage in polyolefin IV bags at 4 °C. In parallel, the impact of a storage temperature excursion at 25 °C for three days and storage of the vial before opening at room temperature (25 ± 2 °C) and after opening at 4 °C was studied.
Methods
The vials were supplied by Zentiva laboratory. The vials (three batches) were diluted to the final concentrations of 1.4 or 16.5 mg/mL in 100 mL IV bags of NaCl. The IV bags and vials were stored at 4 °C and at room temperature throughout the duration of the study. The physico-chemical stability was tested using the following methods: turbidimetry, UV spectrometry and fluorescence, dynamic light scattering, ion exchange and steric exclusion chromatography, pH, osmolality and density.
Results
Out of all the parameters studied, for the two concentrations and standard storage conditions (90 days at +4 °C) or after a three-day temperature excursion at +25 °C, no modification was detected for the three batches tested with respect to physical and chemical stability. Hence, no signs of physical instability were observed, with, in particular, the absence of formation of submicron or micron sized aggregates and particles. The steric exclusion chromatography profiles did not demonstrate any oligomer formation or molecular structure rupture. Ion exchange chromatography did not demonstrate any significant modification in the distribution of charge variants. Derivative UV and fluorescence spectral analysis did not demonstrate any modification. The thermal denaturation curves were identical, suggesting the absence of thermodynamic destabilisation. Identical results were observed for the vials stored for 60 days at 4 °C after opening. Finally, only ion exchange chromatography demonstrated a slight change after 45 days of storage at 25 °C for vials before opening.
Conclusions
After dilution in sterile conditions with 0.9% NaCl in polyolefin IV bags, at the usual concentrations of 1.4 and 16.5 mg/mL, the Bevacizumab biosimilar Alymsys® is stable for at least three months at 4 °C protected from light and after a three-day temperature excursion at +25 °C. The same conclusions can be reached for the 25 mg/mL vials stored for 60 days at +4 °C after opening. However, the stability of vials stored at 25 °C before opening is no longer guaranteed beyond 15 days.

Y-site administration of electrolyte solutions and injectable acetaminophen-A physical compatibility study with combinations frequently used in pediatric intensive care and anesthesia. Paediatr Anaesth 2023; 33:69-78. [PMID: 36214581 DOI: 10.1111/pan.14569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 09/28/2022] [Accepted: 09/03/2022] [Indexed: 01/20/2023]
Abstract
AIM Determination of the physical compatibility of acetaminophen and two different electrolyte solutions (an isotonic, balanced electrolyte solution and a hypotonic, glucose containing electrolyte solution) with drugs frequently used in routine pediatric intensive care. METHODS Analytical investigations for frequently used combinations without pre-existing data were performed. Visual and microscopic observations according to the European Pharmacopeia as well as pH measurements and ultraviolet visible spectrometry at wavelengths of 350, 410 and 550 nm were conducted to analyze physical compatibility. All measurements were performed immediately after mixing as well as 1, 4, and 24 h after. RESULTS In total, 42 combinations were analyzed. Visual incompatibilities were found with pantoprazole and diazepam with both electrolyte solutions. For furosemide, a particle formation in mixture with the hypotonic glucose-containing electrolyte solution and a change in pH ≥ 0.5 after 24 h with both electrolyte solutions were observed. Ampicillin, cefuroxime, diazepam, furosemide, linezolid, meropenem, and pantoprazole showed an aberration of the absorbance ≥0.04 (350 nm/410 nm) or ≥0.01 (550 nm) in the photometric measurements with the electrolyte solutions. For acetaminophen, a physical incompatibility was observed with ampicillin, diazepam, furosemide, and pantoprazole. CONCLUSION Most of the analyzed combinations showed no signs of physical incompatibility and may therefore be administered via the same Y-site. However, diazepam, furosemide, and pantoprazole should not be administered simultaneously with acetaminophen or both electrolyte solutions.

Abstract
Over the past several decades, great progresses have been made for the pharmaceutical industry of monoclonal antibody (mAb). More and more mAb products were approved for human therapeutics. This review describes the state of art of utilizing neutron scattering to investigate mAbs, in the aspects of structures, dynamics, physicochemical stability, functionality, etc. Firstly, brief histories of mAbs and neutron scattering, as well as some basic knowledges and principles of neutron scattering were introduced. Then specific examples were demonstrated. For the structure and structural evolution investigation of in dilute and concentrated mAbs solution, in situ small angle neutron scattering (SANS) was frequently utilized. Neutron reflectometry (NR) is powerful to probe the absorption behaviors of mAbs on various surfaces and interfaces. While for dynamic investigation, quasi-elastic scattering techniques such as neutron spin echo (NSE) demonstrate the capabilities. With this review, how to utilize and take advantages of neutron scattering on investigating structures and dynamics of mAbs were demonstrated and discussed.

Abstract
Food-processing and pharmaceutical industries share a lot of stability issues against the same physical, chemical, and microbiological phenomena. They also share some solutions to improve the stability as the use of preservatives and packaging. Ecological concerns lead to the development of tremendous innovations in food. Some of these innovations could also be beneficial in the pharmaceutical domain. The objective of this review is to evaluate the potential application of these findings in the pharmaceutical field and the main limits in terms of toxicity, environmental, economic and regulatory issues. The principal factors influencing the shelf-life were highlighted through the description of the stability studies usually performed in the pharmaceutical industry (according to European guidelines). To counter those factors, different solutions are currently available as preservatives and specific packaging. They were described and debated with an overview of recent food innovations in each field. The limits of the current solutions in the pharmaceutical field and the innovation in the food field have inspired a critical pharmaceutical outlook. The active and intelligent packaging for active pharmaceutical ingredients of the future is imagined.

Eur J Pharm Biopharm 2022; 176:54-74. [PMID: 35595030 DOI: 10.1016/j.ejpb.2022.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 05/05/2022] [Accepted: 05/07/2022] [Indexed: 11/19/2022]
Abstract
The stability of the monoclonal antibody Ipilimumab, the active ingredient of Yervoy®, used for the treatment of different types of cancer, has been investigated. Shaking/temperature, light exposure and dilution, protein drug renowned stressors, were applied on a 30-45-day series of experiments to observe the physicochemical and biological behavior of the molecule. Ipilimumab demonstrated stability under shaking and heat up to 45 days, without any unfolding during the induced combined stressors. Under artificial sunlight, the mAb showed to be sensitive even under the minimum dose tested (720 kJ/m2) with formation of aggregates, particularly when diluted in glucose solution. The light-induced soluble aggregates were higher in the case of diluted samples irradiated with much higher light doses (10460 kJ/m2). The aggregation of Ipilimumab took place also by irradiating the non-diluted formulation, indicating that the excipients did not protect completely the drug from photodegradation. Amino acid oxidation and deamidation were found. Anyway, after irradiation with both light doses, soluble Ipilimumab maintained its typical β-sheets structure, and the tertiary structure was nearly maintained compared to the dark. As an additional stressor test, the effect of dilution on the formulation was monitored by using a saline solution (1 mg/mL Ipilimumab) applied during hospital infusion. After two days from dilution, the protein exhibited aggregation and chemical modifications including oxidation and deamidation. When stability conditions were compromised, the viability of human cell lines treated with the stressed formulation slight decreased suggesting low potential biological toxicity of the modified mAb. As this study has demonstrated the susceptibility of Ipilimumab to light, specific solutions, and excipients as well as the use of safe light in manufacturing, handling, and storage of this drug should be promoted. Moreover, the use of proper primary and secondary packaging should be indicated to avoid the detrimental effect of light on the mAb structure and efficacy. A detailed understanding of Ipilimumab physicochemical properties, integrity, and stability could assure the best storage and manipulation conditions for its safe and successful application in cancer therapy.

Abstract
Abstract
Objectives
Patients hospitalized in intensive care units often require multiple drug infusions. Due to limited intravenous accesses, concomitant administration of drugs in the same infusion line is often necessary. Compatibility studies of Y-site administration are available in the literature, but data of several combinations are lacking. Previous work from d’Huart et al. have performed an observation of the administration of injectable drugs in three adults ICUs and identified a list of Y-site administration without compatibility data. The objective of this study was to test the physical compatibility of the main drugs of this list used in pairs in Y-site infusions in critical care units, in order to provide new compatibility data to the literature, and to secure the administration of intravenous drugs.
Methods
The physical compatibility in Y-site of nine drugs with other drugs commonly used in intensive care units has been tested. Examinations were performed on 75 mixtures after their preparation, after 1 and 4-h storage. This evaluation included a visual examination with a search for precipitation formation, color change, gas formation, and a subvisual evaluation: absorbance measurements by UV-visible spectrophotometry at 350, 410 and 550 nm, and Light Obscuration Particle Count Test. The pH evaluation was performed at each time of analysis.
Results
Laboratory tests led to an overall compatibility of 68.0% for all mixtures obtained in this study. Nefopam was found to be quite compatible with other drugs (95.0%). Amiodarone hydrochloride (84.6%), acetylsalicylic acid (80.0%), clonidine hydrochloride (75.0%) and insulin (71.4%) were compatible with other drugs too. Atenolol (42.9%), furosemide (25.0%), heparin sodium (25.0%) showed less compatible results. Pantoprazole sodium (0.0%) was not at all compatible with the other drugs analyzed.
Conclusions
By the results of these laboratory tests, missing compatibility data are now available, providing additional information to the literature.

Abstract
The use of continuous infusion to improve the therapeutic efficacy of time-dependent antibiotics has been demonstrated. There is still a lack of data to safely perform these continuous infusions. The objectives in this study were to evaluate the stability by using stability-indicating methods (High-Performance Liquid Chromatography) of 16 antibiotics in concentrated solutions, especially for administration in intensive care units and solutions in elastomeric diffusers at 37 °C for outpatient parenteral antimicrobial therapy. The solutions were considered stable if the percentage of the drug was ≥90%, and the colour and clearness remained unchanged. In syringes, the stability data vary from 4 to 8 h (h) for meropenem in Dextrose 5% (D5W) and Normal Saline (NS), respectively, 6 h for cefotaxime, 12 h for cefoxitin, and 24 h for aztreonam, cefazolin, cefepime, cefiderocol, ceftazidime/avibactam, ceftolozane/tazobactam in NS and D5W, and in water for injection for cloxacillin. A stability period of 48 h has been validated for vancomycin (D5W), aztreonam, and piperacillin/tazobactam. Cefoxitin, cefazolin, cefepime, cefotaxime, cloxacillin, and piperacillin are unstable for diffuser administration. In diffusers, stability times vary from 6 h for cefiderocol, 8 h for ceftazidime, 12 h for ceftazidime/avibactam and ceftolozane/tazobactam (NS), 24 h for temocillin (NS) and piperacillin/tazobactam (D5W), up to 48 h for aztreonam and vancomycin. Solutions stored at 37 °C are less stable and allow the administration of seven antibiotics using diffusers.

Comprehensive Analysis of Nivolumab, A Therapeutic Anti-Pd-1 Monoclonal Antibody: Impact of Handling and Stress. Pharmaceutics 2022; 14:pharmaceutics14040692. [PMID: 35456527 PMCID: PMC9025134 DOI: 10.3390/pharmaceutics14040692] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 03/10/2022] [Accepted: 03/17/2022] [Indexed: 11/16/2022] Open
Abstract
Nivolumab, formulated in the medicine Opdivo® (10 mg/mL), is a therapeutic monoclonal antibody (mAb) used in the treatment of different types of cancer. Currently, there is insufficient knowledge about the behaviour of this protein with regards to the risk associated with its routine handling or unintentional mishandling, or when subjected to stress conditions in hospitals. These conditions can be simulated in forced degradation studies, which provide an in-depth understanding of the biophysical and biochemical properties of mAbs. In this study, we carried out a physicochemical and functional characterisation of nivolumab, which was subjected to various stress conditions: heat, freeze/thaw cycles, agitation, light exposure and high hypertonic solution. We used a wide range of analytical techniques: Far-UV CD, IT-FS, DLS, SE/UHPLC(UV)-[Native]MS, and ELISA. The results show that exposure to light was the stress test with the greatest impact on the samples, revelling the formation of non-natural dimers and a different isoform profile. In addition, nivolumab (Opdivo®) demonstrated stability up to 60 °C (1 h). As regards functionality all the nivolumab (Opdivo®) stressed samples were found to be stable except for those subjected to light and agitation, and to a lesser extent, those subjected to FTC 5 and NaCl stresses.

Abstract
Abstract
Objectives
Azacitidine is a pyrimidine nucleoside analogue whose stability is temperature dependent. Numerous publications have studied the stability of this drug with discordant results. The purpose of this work is to study the stability of azacitidine suspensions under different conditions to allow preparation in advance: vials stored at room temperature or between 2 and 8 °C, reconstituted with refrigerated water for injection (WFI) or frozen/thawed WFI, azacitidine suspensions stored at room temperature, 2–8 °C or at −20 °C. The feasibility of a vented ChemoClave® Spike vial was also tested to reconstitute and collect azacitidine to aid the preparation stage.
Methods
The stability study was performed by HPLC coupled to a photodiode array detector. The method was validated according to ICH Q2(R1). Two syringes were prepared for each analysis condition and two samples were realised for each syringe at each time of the analysis. For a storage at 2–8 °C, analyses were performed for up to 168 h. The stability was studied after 2 h at room temperature. For frozen storage, the stability was studied after 28 days.
Results
Azacitidine 25 mg/mL suspensions stored between 2 and 8 °C, prepared with refrigerated WFI or frozen/thawed WFI, retained more than 90% of the initial concentration for 96 h and then for 2 h at room temperature. Prepared with frozen/thawed WFI, azacitidine 25 mg/mL suspensions stored at −20 °C for 28 days and then 72 h between 2 and 8 °C after thawing, retained more than 90% of the initial concentration. When using a Spike system compared to using a needle for reconstitution and collection of the suspension, the results obtained by HPLC showed a decrease of 1.47% in the concentration of azacitidine. The comparisons of the volumes withdrawn after reconstitution were similar when using a Spike system or a needle.
Conclusions
Azacitidine 25 mg/mL suspensions reconstituted with refrigerated WFI were chemically stable for 4 days when stored at 2–8 °C whatever the storage of vials (refrigerator or room temperature), and 2 h at room temperature. A storage of azacitidine 25 mg/mL suspensions in syringes prepared with frozen/thawed WFI at −20 °C has been validated for up to 28 days, leading to the possibility to prepare in advance. A Spike device can be used to reconstitute and collect azacitidine.

Physicochemical Stability Study of the Morphine-Ropivacaine-Ziconotide Association in Implantable Pumps for Intrathecal Administration. Neuromodulation 2022:S1094-7159(21)06177-8. [PMID: 35088750 DOI: 10.1016/j.neurom.2021.10.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 08/26/2021] [Accepted: 09/07/2021] [Indexed: 11/17/2022]
Abstract
PURPOSE This study aimed to investigate the physicochemical stability of morphine-ropivacaine-ziconotide mixtures used in intrathecal analgesia. MATERIALS AND METHODS Eight mixtures were studied to assess their stability profiles according to the initial drug concentrations used. The solutions obtained were put in implantable pumps and stored at 37 °C over a period of 60 days. Assays were performed using ultra high-pressure liquid chromatography. Turbidity and pH were also measured throughout the study. RESULTS Results confirmed excellent physicochemical stability for morphine and ropivacaine. Concerning ziconotide, three of the eight mixtures did not show any sign of chemical instability: average concentrations remained constant throughout the 60 days. A decrease of the concentration was observed for the five other mixtures. Moreover, the appearance of a degradation product linked to oxidation confirmed the ziconotide degradation. CONCLUSIONS All these results are in favor of a physicochemical stable preparation for three of the mixture profiles when stored in implantable pumps at 37 °C up to 60 days. For the five others, the efficacy should decrease over time owing to the degradation of ziconotide. The decrease in kinetics of the ziconotide concentration depends on the mixing profile. One possibility is to adapt the filling intervals according to the profile of the mixture. Finally, the results show the period of stability ensuring maximum analgesic efficacy for the eight mixture profiles studied.

Abstract
Stability studies performed by the pharmaceutical industry are principally designed to fulfill licensing requirements. Thus, post-dilution or post-reconstitution stability data are frequently limited to 24 h only for bacteriological reasons, regardless of the true physicochemical stability which could, in many cases, be longer. In practice, the pharmacy-based centralized preparation may require preparation in advance for administration, for example, on weekends, holidays, or in general when pharmacies may be closed. We report an innovative strategy for storing resuspended solutions of azacitidine, a well-known chemotherapic agent, for which the manufacturer lists maximum stability of 22 h. By placing the syringe with the azacitidine reconstituted suspension between two refrigerant gel packs and storing it at 4 °C, we found that the concentration of azacitidine remained above 98% of the initial concentration for 48 h, and no change in color nor the physicochemical properties of the suspension were observed throughout the study period. The physicochemical and microbiological properties were evaluated by HPLC–UV and UHPLC-HRMS analysis, FTIR spectroscopy, pH determination, visual and subvisual examination, and sterility assay. The HPLC-UV method used for evaluating the chemical stability of azacitidine was validated according to ICH. Precise control of storage temperature was obtained by a digital data logger. Our study indicates that by changing the storage procedure of azacitidine reconstituted suspension, the usage window of the drug can be significantly extended to a time frame that better copes with its use in the clinical environment.

Abstract
Bearing in mind the several medicinal properties of Mentha genus, this work aimed to evaluate the anti-proliferative potential of the ethanolic extract (EE) and fractions from M. aquatica L aerial parts. Using the anti-proliferative protocol developed by the NCI/USA, four fractions (F2 - F4 and F6) obtained from EE showed promising anti-proliferative profile against a panel of human tumor and non-tumor cell lines. After 24-h exposure, F2 (0.25 µg/mL) showed potent and irreversible anti-proliferative effect without inducing cell cycle arrest in both NCI-H460 and MCF-7 cells, without (anti) estrogenic activity. These effects were lost after storage of F2 diluted in dimethyl sulfoxide at -80 °C during 2 weeks. Analysis by gas chromatography coupled to mass detection evidenced some chemical changes induced by F2 storage in solution. The present study demonstrated the anti-proliferative effect of M. aquatica. Further studies are necessary to determine better storage conditions to enhance F2 stability.

Abstract
PURPOSE To investigate the long-term chemical and physical stability of 5-mg/mL acyclovir solution in polypropylene bags stored at 5°C ± 3°C for 2 months in order to determine the feasibility of batch production by a centralized intravenous additive service. METHODS Eight empty 100-mL polypropylene bags (bags A) and 8 empty 250-mL bags (bags B) were respectively filled with 60 mL and 200 mL of 5-mg/mL acyclovir and 0.9% sodium chloride injection (NaCl) under aseptic conditions through a semiautomated manufacturing process and vacuum packed before storage at 5°C ± 3°C. Four bags A and 4 bags B were tested for chemical stability via a stability-indicating high-performance liquid chromatography (HPLC) method immediately after preparation (time 0) and after 7, 14, 21, 28, 35, 42, and 63 days. Samples for microbiological assay were collected on days 0 and 63 from 4 bags A and 4 bags B immediately after breaking the vacuum. Osmolality, pH, and physical stability were assessed by visual examination, Subvisible particle counting was performed on 6 additional bags (3 each of bags A and B). RESULTS Mean percentage loss of acyclovir relative to the mean experimental concentration at time 0 was below 5% over the 63-day study period.. No significant differences of pH, no change in color and no precipitate were observed during the study. Subvisible particle counts were compliant with European Pharmacopoeia requirements. Acyclovir solutions remained sterile over the 63 days of the study. CONCLUSION Extemporaneously prepared acyclovir 5 mg/mL solutions in 0.9% NaCl stored in polypropylene bags were chemically and physically stable over 63 days when stored at 5°C ± 3°C.

Abstract
Abstract
Objectives
Concomitant administration of two incompatible drugs in the same infusion line can lead to a precipitation which could have clinical consequences for patients. The objective of this work was to study the physical compatibility of injectable posaconazole with other drugs commonly used in an adult hematology care unit.
Methods
The most widely used injectable drugs co-administered with posaconazole have been listed with a total of 19 drugs. For some drugs, different conditions have been tested. A total of 24 solutions were produced (not including the posaconazole). In the absence of compatibility data, the physical compatibility was tested for each pair including one of the 24 solutions and posaconazole. For each pair studied, three different ratios were prepared (9:1, 1:1, 1:9). Visual evaluations were performed after the mixture, after one and 4 h.
Results
Seventy two mixtures have been realised: 55.56% of pairs (n=40/72) resulted in a precipitation, against 44.44% (n=32/72) with no visual modification after a 4-h storage. On the 19 drugs tested, only filgrastim and tacrolimus showed no visual change with posaconazole during a 4-h storage.
Conclusions
In majority of cases, posaconazole was not compatible with drugs having alkaline pH, commonly used in a hematology unit.

Abstract
BACKGROUND Patients undergoing chemotherapeutic treatment are currently treated by a concomittent infusion of alizapride and ondansetron. To optimise the procedure and to ensure patients' safety, the admixture could be prepared in advance by the Centralized Intravenous Additive Service (CIVAS) provided that the stability of the mixture has been proven beforhand to reduce nausea and vomiting.Aim of the study: to evaluate the long-term stability of an admixture of alizapride 0.926 mg/l and ondansetron 0.074 mg/ml in 0.9% sodium chloride polyolefin bags stored at 5 ± 3°C. MATERIAL AND METHODS Five polyolefin bags containing 100 ml sodium chloride 0.9% added with 4 ml alizapride (100 mg) and 4 ml ondansetron (8 mg) were prepared in aseptic conditions and stored at 5 ± 3°C for 56 days. Periodically, physical stability tests were performed including: pH measurements, optical density measurements at 350, 410 and 550 nm to track turbidity appearance, visual and microscopical inspections to detect colour changes, precipitation, microaggregates or crystals. The concentrations of the solutions were measured by High Performance Liquid Chromatography coupled with an UV detector. RESULTS There was no change in pH and optical densities during the study period. Visual and microscopical inspections didn't show any change of colour neither precipitation, microaggregate or crystal. The alizapride and ondansetron concentrations remained stable over the study. CONCLUSION The admixture of alizapride and ondansetron in 0.9% sodium chloride solution polyolefin bags is physicochemically stable up to 56 days at 5 ± 3°C. These results support the possibility of preparing the solutions in advance by a CIVAS.

Abstract
Myopia is an ophthalmic condition affecting more than 1/5th of the world population, especially children. Low-dose atropine eyedrops have been shown to limit myopia evolution during treatment. However, there are currently no commercial industrial forms available and there is little data published concerning the stability of medications prepared by compounding pharmacies. The objective of this study was to evaluate the stability of two 0.1 mg/mL atropine formulations (with and without antimicrobiobial preservatives) for 6 months in two different low-density polyethylene (LDPE) multidose eyedroppers. Analyses used were the following: visual inspection, turbidity, chromaticity measurements, osmolality and pH measurements, atropine quantification by a stability-indicating liquid chromatography method, breakdown product research, and sterility assay. In an in-use study, atropine quantification was also performed on the drops emitted from the multidose eyedroppers. All tested parameters remained stable during the 6 months period, with atropine concentrations above 94.7% of initial concentration. A breakdown product (tropic acid) did increase slowly over time but remained well below usually admitted concentrations. Atropine concentrations remained stable during the in-use study. Both formulations of 0.1 mg/mL of atropine (with and without antimicrobial preservative) were proved to be physicochemically stable for 6 months at 25 °C when stored in LDPE bottles, with an identical microbial shelf-life.

Abstract
Background and Objective: Infusion containing lorazepam is used by geriatric department to limit anxiety disorders in the elderly. Currently, these infusions are prepared according to demand by the nursing staff, but the preparation in advance in a centralized service could improve quality of preparation and time management. The aim of this study was to investigate the long-term stability of this infusion in polypropylene syringes stored at 5 ± 3°C. Then, results obtained were compared with stability data of lorazepam in syringes stored at room temperature, glass bottles at 5 ± 3°C, and glass bottles at room temperature. Method: Eight syringes and 6 bottles of infusion were prepared by diluting 1 mL lorazepam 4 mg in 23 mL of NaCl 0.9% under aseptic conditions. Five syringes and 3 bottles were stored at 5 ± 3°C and 3 syringes and 3 bottles were stored at room temperature for 30 days. During the storage period, particle appearance or color change were periodically checked by visual and microscope inspection. Turbidity was assessed by measurements of optical density (OD) at 3 wavelengths (350 nm, 410 nm, 550 nm). The stability of pH was also evaluated. The lorazepam concentrations were measured at each time point by high-performance liquid chromatography with ultraviolet detector at 220 nm. Results: Solutions were physically unstable in syringes at 5 ± 3°C after 4 days: crystals and a drop of OD at 350 nm were observed. However, pH was stable. After 2 days, solutions were considered as chemically unstable because a loss of lorazepam concentration higher than 10% was noticed: the lower 1-sided confidence limit at 95% was below 90% of the initial concentration. To assess temperature and polypropylene influence, results were compared with those obtained for syringes at room temperature and bottles at 5 ± 3°C and room temperature. Precipitation, drop of OD at 350 nm, and chemical instability were observed in all conditions. Conclusion: Solutions of lorazepam were unstable after 2 days in syringes at 5 ± 3°C. Preparation in advance appears, therefore, not possible for the clinical use. Storage conditions (temperature and form) do not improve the stability.

Abstract
AbstractIn the context of batch production of cytotoxic drugs in hospital pharmacies with the need of sterility testing, the objective was to validate the use of Rapid Microbiological Method (RMM), and to develop adequate neutralization method in case of inhibition of bacterial growth. The potential microbiological growth inhibitory effect of three anticancer drugs (5 fluorouracil, irinotecan and oxaliplatin) selected for batch production was assessed on BacT/ALERT® system. Among cytotoxic drugs, only 5FU exhibited inhibitory effect on microbiological growth using rapid microbiological method. To counteract this effect our purpose was to use neutralizing agents complexing the drug i. e. activated carbon or ion exchange resins. The microbiological bactericidal concentration of 5FU was very low (1.10–4 mg/mL) indicating the absolute need to neutralize the whole drug before sterility test. The complexation was validated by High Performance Liquid Chromatography control of the residual 5FU concentration in solution after the use of neutralizing agents. Only activated carbon was able to fully capture 5FU when previously diluted at 5 mg/mL. Conversely, the resins, in the condition of the study, were not able to fully capture 5FU whatever the dilution. The microbiological growth on BacT/ALERT® system after active carbon treatment was successfully confirmed with Staphylococcus aureus. Based on this validation results a method was then developed to routinely be able to perform sterility test of the batches produced and was confirmed on five microbiological species (i. e. S. aureus, Pseudomonas aeruginosa, Bacillus subtilis, Candida albicans, Aspergillus brasiliensis). Our work gives a new insight for considering sterility testing by rapid microbiological method even for drugs exhibiting inhibitory effect on microbiological growth.

Abstract
Background and objective Factor VIII (FVIII) is indicated for the prevention or treatment of bleeding in patients with hemophilia A. FVIII product stability under high and fluctuating temperatures is important, particularly for patients who reside in, or travel to, regions with high ambient temperatures, as they may remove their product from the refrigerator and return it, unused, multiple times. We evaluated the effect of variable temperature storage conditions, including up to 40 °C, on the stability of the recombinant FVIII product, turoctocog alfa. Methods Turoctocog alfa dry powder stability was assessed when moved between storage conditions of 5 °C (ambient humidity) and 40 °C (75% relative humidity) multiple times over a 2-month period, followed by long-term storage at 40 °C for 3 months and 5 °C for 1 month. Three product strengths (250, 1500, and 3000 IU), including the lowest and highest doses, were evaluated. Stability assessments included potency, purity, oxidized forms, high molecular weight protein (HMWP), and water content. Results Overall, the three doses of turoctocog alfa tested remained stable under varying temperature conditions, without any potency or purity impairment, nor were any major increases in oxidized forms, HMWP, or water content observed. All results were within shelf-life specification limits. Conclusion The results demonstrated that turoctocog alfa can be subjected to variable storage conditions, including cycling between 5 °C and ≤ 40 °C, and subsequent storage for 3 months up to 40 °C, without loss of stability. This suggests that turoctocog alfa may offer greater product storage flexibility for patients in everyday practice, with a potential reduction in wastage.

Abstract
Purpose Calcium levofolinate (CaLev) for intravenous administration is commercially available as a powder that must be reconstituted for injection or reconstituted and then diluted before administration. The lack of stability data on CaLev solutions renders necessary extemporaneous manual preparation, preventing the use of automated/semi-automated systems, with a consequent loss in terms of quality and safety. Methods The present work assessed the chemical–physical and microbiological stability of CaLev prepared in sodium chloride 0.9%, glucose 5% and water for injections and stored in polyolefin/polyamide bags and polypropylene syringes at 2–8°C protected from light. For this purpose, we developed and validated a new rapid High Performance Liquid Chromatography with Ultra Violet Diode-Array Detection (HPLC-UV-DAD) method. Results The samples tested were stable for 14 days, retaining >95% of their initial concentration and showing no change in colour, turbidity or pH. Microbiological tests performed on the samples were negative. Conclusions Our results confirmed the analytical stability of CaLev in NaCl 0.9%, glucose 5% and water for injection at concentrations used in clinical practice at our institute. This enables our centralized laboratory to organize the preparation of this drug in advance and the use of robots rather than manual preparation reduces the workload and the risk of preparation errors.

Abstract
Background and objective Infusion containing paracetamol, alizapride, ketorolac and tramadol is used after a general anaesthesia in order to limit pain, fever and nausea. Currently, these infusions are prepared according to demand in the anaesthesia unit, but the preparation in advance could improve quality of preparation and time management. The aim of this study was to investigate the long-term stability of this infusion in glass bottles at 5°C ± 3 °C. Method Five bottles of infusion were stored at 5°C ± 3 °C for 60 days. A visual and microscope inspection were performed periodically to observe any particle appearance or colour change. pH and absorbance at three wavelengths were measured. The concentrations were measured by ultra-high performance liquid chromatography - diode array detection. Results Multiple verifications were performed during the first 35 days and no crystal, impurity or colour change were observed. At the next time point (42nd day), crystals were visible to the naked eye. pH and absorbance at 350 nm and 550 nm were stable. A slight increase in the absorbance at 410 nm was observed during the study, suggesting that a degradation product could be formed and absorb at this wavelength. The infusion was considered chemically stable while the lower one-sided prediction limit at 95% remains superior to 90% of the initial concentration. Concentration measurements demonstrated that ketorolac and alizapride remained stable in the infusion for 35 days. The stability of tramadol was 28 days. However, degradation of paracetamol was much faster given that concentration has fallen below 90% of the initial concentration after 7 days. Conclusion Infusion of paracetamol, alizapride, ketorolac and tramadol remains stable for 7 days in glass bottles at 5°C ± 3 °C and could be prepared in advance with these storage conditions.

Abstract
Introduction Nefopam has been reported to be effective in postoperative pain control with an opioid-sparing effect, but the use of nefopam can lead to nausea and vomiting. To prevent these side effects, droperidol can be mixed with nefopam. In intensive care units, high concentrations of nefopam and droperidol in syringes can be used with a continuous flow. Objectives The first objective of this work was to study the physicochemical stability of a nefopam solution 2.5 mg/mL diluted in NaCl 0.9% in polypropylene syringes immediately after preparation and after 6, 24 and 48 hours at room temperature. The second objective was to study the physicochemical stability of mixtures of nefopam 2.5 mg/mL and droperidol 52 µg/mL diluted in NaCl 0.9% in polypropylene syringes at room temperature over 48 hours. Materials and methods Three syringes for each condition were prepared. For each time of analysis, three samples for each syringe were prepared and analysed by high performance liquid chromatography coupled to photodiode array detection. The method was validated according to the International Conference on Harmonisation Q2(R1). Physical stability was evaluated by visual and subvisual inspection (turbidimetry by UV spectrophotometry). pH values were measured at each time of analysis. Results Solutions of nefopam at 2.5 mg/mL and the mixture of nefopam 2.5 mg/mL with droperidol 52 µg/mL, diluted in NaCl 0.9%, without protection from light, retained more than 90% of the initial concentration after 48 hours storage at 20-25°C. No modification in visual or subvisual evaluation and pH values were observed. Conclusion Nefopam solutions at 2.5 mg/mL and the mixture of nefopam 2.5 mg/mL with droperidol 52 µg/mL diluted in NaCl 0.9% were stable over a period of 48 hours at room temperature. These stability data provide additional knowledge to assist intensive care services in daily practice.

Abstract
Objectives Opioid-free anaesthesia is a treatment strategy of pain management based on the use of drugs such as lidocaine, ketamine and dexmedetomidine that do not interact significantly with opioid receptors. In particular, these drugs are used by anaesthesiologists to ensure adequate levels of analgesia during surgical procedures for burn patients such as daily wound dressings and graft surgeries. Furthermore, for hypothermia prevention and wound-healing purposes, ambient temperature must be kept high for these patients, usually between 27°C and 30°C. To facilitate the use of this technique, clinicians want to mix lidocaine and ketamine in the same syringe. No stability data is available to determine the feasibility of this admixture and at this temperature. The objective was to study the physicochemical stability of lidocaine 20 mg/mL with ketamine 2.5 mg/mL diluted with 0.9% sodium chloride (0.9% NaCl) stored at 28°C in polypropylene syringe for 48 hours. Methods Physical stability was evaluated by visual examination and by measuring turbidity with a spectrophotometer. Chemical stability was determined after preparation and after 6, 24 and 48 hours of conservation with a high performance liquid chromatography and pH measurements. The method was validated according to International Conference on Harmonisation Q2(R1) guidelines. Results Both lidocaine (99.98%±1.44%) and ketamine (100.70%±0.95%) retained more than 95% of their initial concentration after 48 hours storage. pH measurements remained stable over the course of the study (less than 0.21 point of variation). No signs of physical instability were observed after visual and subvisual inspections. Conclusions The physicochemical stability of lidocaine 20 mg/mL and ketamine 2.5 mg/mL diluted with 0.9% NaCl in a polypropylene syringe stored at 28°C protected from light was demonstrated for 48 hours. This infusion technique is therefore feasible from a pharmaceutical point of view in burn-unit settings.

Abstract
Introduction According to the manufacturers, the diluted solution of etoposide should not exceed 0.4 mg/mL because precipitation may occur. For high doses or for patients requiring fluid restrictions, etoposide phosphate may be an option but shortages occurs frequently. The objective of this work was to study the stability of etoposide solutions between 0.38 and 1.75 mg/mL, diluted in 0.9% sodium chloride (0.9% NaCl) or 5% glucose (G5%) in polyolefin bags, stored at 25°C and between 2°C to 8°C, in a 61-day period. This study also observed the impact of an infusion pump on the physical and chemical stability of etoposide solutions. Materials and method Chemical stability was analysed at days 0, 9, 16, 21, 28 and 61 by high-performance liquid chromatography. Physical stability was evaluated by visual and subvisual inspection. The action of an infusion pump on solutions was evaluated to verify the impact of the mechanical pumping action on the etoposide solutions. This investigation was performed at day 61, at the end of the study. Results Etoposide solutions diluted at 0.38, 0.74 and 1.26 mg/mL in G5% and stored at 25°C were stable for 61 days and at 1.75 mg/mL for 28 days. In 0.9% NaCl, etoposide was less stable, with more precipitations observed. The action of an infusion pump has not caused any physical modifications. Conclusion Storage at 25°C and G5% as diluent are recommended for etoposide high concentration with 61-day stability up to a concentration of 1.26 mg/mL and 28-day stability up to a concentration of 1.75 mg/mL. As a precaution, the use of an administration set with an in-line micro-filter is nevertheless recommended. Storage at 2°C to 8°C and the use of 0.9% NaCl increase the risk of precipitation.

Abstract
This work aims to evaluate the possible impact of interactions between bevacizumab solutions and an implantable port equipped with a silicone or a polyurethane catheter after infusion through a complete infusion set-up in simulated use conditions. Physico-chemical and structural stability of bevacizumab solution was assessed by visual examination, subvisible particles counting, dynamic light scattering, size exclusion chromatography and ion exchange chromatography. Mechanical properties of the catheters were evaluated by measuring Shore A hardness, strain at break, strain at stress and Young's modulus. The physico-chemical surface state of the catheters was assessed by FTIR-ATR spectroscopy, scanning electron microscopy (SEM) and by water contact angle measurement. The analysis of the bevacizumab solution did not highlight any signs of instability or loss of active substance. Mechanical properties of both materials remained unchanged after the infusion. During material analysis, a decrease in water contact angle observed after infusion and was more pronounced for polyurethane catheters than for silicone, possibly due to bevacizumab adsorption or possible leachable extraction from the materials. Surface modifications were also noted at SEM. This study did not highlight any modifications that could alter the quality of the bevacizumab infusion, nor of the infusion catheter in polyurethane or silicone, despite a modification of surface hydrophilicity. Even if after a single infusion, implantable ports remained safe to use, they aim to be used for several infusion of various drugs during their lifetime, and further studies are needed to assess the impact of repeated infusions.

Abstract
BACKGROUND In severe infections, high-concentration vancomycin may be administered by continuous infusion. The dosage of vancomycin may reach 60 mg/kg per day. OBJECTIVES To study the feasibility of preparing high-concentration vancomycin solutions (40 to 83.3 mg/mL), to study the effect of an electric syringe pump on the physical stability of high-concentration vancomycin, and to study the stability of vancomycin 62.5 and 83.3 mg/mL in 0.9% sodium chloride (0.9% NaCl) or 5% dextrose in water (D5W) with storage up to 48 h at room temperature. METHODS The following sets of syringes were prepared: (1) 4 syringes of vancomycin in 0.9% NaCl for each of 5 concentrations between 40 and 83.3 mg/mL (total 20 syringes); (2) 6 syringes at 83.3 mg/mL in 0.9% NaCl and 6 syringes at 83.3 mg/mL in D5W; and (3) 30 syringes at 83.3 mg/mL in D5W. Visual inspection was performed for all 3 syringe sets, and subvisual inspection for sets 1 and 2 (for periods of 24 h for set 1 and 48 h for sets 2 and 3). One syringe of vancomycin 83.3 mg/mL with each solvent was inserted into an electric syringe pump, and samples from the infusion line and collected after transit through the pump were inspected visually. Chemical stability was evaluated by high-performance liquid chromatography, and physical stability, pH, and osmolality were investigated. RESULTS For all sets of syringes, no physical modification was observed over time, nor were any changes observed after transit through the electric syringe pump. In 0.9% NaCl, vancomycin 62.5 and 83.3 mg/mL retained more than 90% of the initial concentration after 48 and 24 h, respectively; however, for the 83.3 mg/mL solution, precipitate was visible after 48 h. In D5W, vancomycin at 62.5 and 83.3 mg/mL retained more than 90% of the initial concentration after 48 h. CONCLUSION It was feasible to prepare high-concentration solutions of vancomycin. The electric syringe pump did not cause any precipitation. Vancomycin in D5W at 62.5 and 83.3 mg/mL was stable over 48 h at room temperature. Precipitation occurred in 0.9% NaCl. D5W is therefore recommended as the solvent for this drug.

Abstract
Background Dose banding (DB) (dose rounding with predetermined variation with prescription) enables in-advance preparation of high-turnover anticancer drugs with potential benefit for pharmacy compounding work flow. Objectives To analyse the impact of potential situations on the efficiency of DB in the pharmacy (safe and maximum storage), calculate preparation lead times and the potential full-time equivalent (FTE) benefit. Methods Candidate intravenous anticancer drugs were selected for logarithmic DB according to prescribing frequency, infusion volume and stability (usage data 2015 of the tertiary Ghent University Hospital, Belgium). With a selected DB set already stored, a 2-week time study (April/November 2015) provided lead times (between prescription and transfer) for just-in-time and DB preparations. A 'maximal' storage (using all drugs with a relative incidence of ≥2% recurrent monthly prescription) and a 'safe' storage scenario (lowest monthly prescribing pattern) were used to calculate the potential future FTE change. Results Mean lead times for DB storage and just-in-time preparation were 17.1 min (95% CI 13.5 to 21.0) and 26.5 min (23.3 to 29.8). For 21 164 yearly preparations with already 5292 in DB (25%), 11 157 and 6 862 could be batch-produced in advance in a maximum storage and safe storage scenario, respectively. The existing FTE in 2015 of 5.41 could then be reduced to 4.91 and 5.27. Conclusion Further development of DB could contribute to pharmacy compounding efficiency.

Abstract
Abstract
Background
Cefotaxime sodium is an antibiotic used to treat severe infections such as in intensive care units (ICUs). The recommended dose of cefotaxime sodium can vary from 3 grams (g) to 24 g per day and publications have demonstrated that continuous administration of cefotaxime sodium is the preferred mode of administration. In ICUs, a minimum volume is used for patients requiring fluid restriction, leading to high concentrations of cefotaxime sodium.
The objective was to study the stability of cefotaxime sodium solutions at 83.3 mg/mL and 125 mg/mL, diluted in 0.9 % sodium chloride (0.9 % NaCl) or in 5 % glucose (G5 %), stored in polypropylene syringes, after the preparation and after a 6-hour and a 12-hour storage at 20–25 °C.
Methods
Three syringes for each condition were prepared. At each time of the analysis, three samples for each syringe were prepared and analysed by high performance liquid chromatography (HPLC) coupled to a photodiode array detector. The method was validated according to the International Conference on Harmonisation Q2(R1). Physical stability was evaluated by visual and subvisual inspection (turbidimetry by UV spectrophotometry at 350, 410 and 550 nm as recommended by the European Consensus Conference). pH and osmolality values were measured at each time of the analysis.
Results
For each solvent, cefotaxime sodium solutions at 83.3 mg/mL and 125 mg/mL retained more than 90 % of the initial concentration after 12 hours. During the stability study, pH values decreased slightly, the intensity of the yellow colour increased and values of absorbance increased progressively for each wavelength and each condition. An additional peak with a relative retention of 3.01 was also observed after the forced degradation gradually increased up to 4.01 % and 3.17 % of the total of surface area of the peaks present on the chromatogram after 12 hours in 0.9 % NaCl and in G5 % respectively.
Conclusions
In view of the results and despite the fact that solutions retained more than 90 % of the initial concentration after HPLC analysis, we propose to limit the stability of cefotaxime sodium in 0.9 % NaCl and G5 % at 83.3 and 125 mg/mL at 6 hours. These stability data of highly concentrated solutions provide an additional knowledge to assist ICUs in daily practice. This work also demonstrates that highly concentrated cefotaxime sodium solutions are physically unstable after a 6-hour storage and cannot be administered as a daily infusion.

Abstract
PURPOSE Chemotherapy preparation units face peaks in activity leading to high workloads and increased stress. The present study evaluated the impact of work overloads on the safety and accuracy of manual preparations. METHOD Simulating overwork, operators were asked to produce increasing numbers of syringes (8, 16, and 24), with markers (phenylephrine or lidocaine), within 1 h, in an isolator, under aseptic conditions. Results were analyzed using qualitative and quantitative criteria. Concentration deviations of < 5%, 5%-10%, 10%-30%, and >30% from the expected concentration were considered as accurate, weakly accurate, inaccurate, and wrong concentrations, respectively. RESULTS Twenty-one pharmacy technicians and pharmacists carried out 63 preparation sessions (n = 1007 syringes). A statistically significant decrease in the manufacturing time for one syringe was observed when workload increased (p < 0.0001). Thirty-nine preparation errors were recorded: 30 wrong concentrations (deviation > 30%), 6 mislabeling, 2 wrong diluents, and 1 wrong drug. There was no statistically significant difference in the mean concentration accuracy of final preparations across the three workloads. The overall error rate increased with the number of preparations made in 1 h: 1.8% for 8 preparations, 2.7% for 16 preparations, and 5.4% for 24 preparations (p < 0.05). CONCLUSION Although pharmacy technicians and pharmacists were able to increase production speeds with no effect on mean concentration accuracy under stressful conditions, there were greater probability errors being made. These results should encourage actions to spread workloads out over the day to avoid peaks in activity.

Abstract
Abstract
Background
The objectives were to perform an observation of the administration of injectable drugs in three ICUs, to identify injectable drugs administered by Y-site infusion or mixed in the same container, to compare with physical compatibility data available in the literature and to test the physical compatibility for missing data.
Methods
An observational study was realised over two weeks and patients receiving more than one injectable drug in the same line simultaneously were included. Physical compatibilities were assessed in pairs by comparing with three databases. For some missing data, three tests were realised for pairs including an anti-infective drug. Visual and subvisual evaluations were performed after the preparation, 1 and a 4-hour storage.
Results
A total of 389 combinations between two injectable drugs was observed for Y-site infusions and 31 mixtures in the same container. According to the literature, 21.1 % associations were physically compatible, 1.8 % as physically compatible potentially, 8.0 % as physically incompatible, 6.4 % have divergent data according to the databases and 62.7 % have no data. Two mixtures were documented. 37 pairs were tested and 70.3 % were physically compatible, 8.1 % were physically incompatible after visual evaluation and 21.6 % after subvisual evaluation.
Conclusions
In the majority of cases, no compatibility data are available in the literature. Laboratory tests give additional information.

Physicochemical stability of norepinephrine bitartrate in polypropylene syringes at high concentrations for intensive care units. ANNALES PHARMACEUTIQUES FRANÇAISES 2019; 77:212-221. [PMID: 30803767 DOI: 10.1016/j.pharma.2019.01.002] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2019] [Revised: 01/15/2019] [Accepted: 01/15/2019] [Indexed: 11/21/2022]
Abstract
OBJECTIVES Norepinephrine is usually used in emergency situations such as in intensive care units (ICUs) for the restoration of blood pressure. The objective was to study the stability of highly-concentrated solutions of norepinephrine at 0.50mg/mL and 1.16mg/mL, diluted in glucose 5% (G5%) in polypropylene syringes, protected or not from light, up to 48h. MATERIALS AND METHODS Chemical stability was analysed by high-performance liquid chromatography coupled to photodiode array detection at each time of the analysis. The method was validated according to the International Conference on Harmonisation Q2(R1). Physical stability was evaluated by visual and subvisual inspection. Three syringes for each condition were prepared. At each time of the analysis, three samples were analysed for each syringe. pH values were evaluated at each moment of the analysis. RESULTS Solutions of norepinephrine at 0.50 and 1.16mg/mL, diluted in G5%, with or without protection from light, retained more than 95.0% of the initial concentration after a 48-hour storage at 20-25°C. No visual and subvisual modification occured during the stability study. No degradation product appearing during the stressed degradation was observed during the study but an additional peak with a relative retention at 0.66 was observed and constant. This peak was identified as 5-hydroxymethylfurfural, a degradation product of glucose. CONCLUSION Norepinephrine diluted in G5% at 0.50mg/mL and 1.16mg/mL was physically and chemically stable over a period of 48hours at room temperature. These stability data of highly concentrated solutions provide additional knowledge to assist intensive care services in daily practice.
