Drying behaviour and visualization of surfactants after co-spray drying of surfactant-stabilized aqueous suspensions. Int J Pharm 2023; 643:123231.

Abstract
Surfactants are widely used in many industries as dispersants or flocculants for suspensions. As the addition of low concentrations of surfactant is sufficient to execute their effect, they barely alter the formulation composition. In this research it was examined whether surfactants, in particular polysorbate 80 (PS80), were suitable as suspension stabilizers for co-spray drying of drug-filler combinations. Therefore, their drying behaviour at different process and formulation settings was studied and mapped by means of fluorescently labelled PS80. Co-spray drying of 10% w/w aqueous suspensions stabilized with 0.1% w/w PS80 resulted in excessive loss of sticky powder in the conical lower part of the drying chamber and the powder conveyor ducts. Up to 16% of powder was lost in the first transporter (i.e. the first part of the conveyor ducts). The amount of powder deposited in the first transporter, and by extension the stickiness of the recovered powder, was correlated with the presence of PS80 on the surface of the spray dried particles. Redistribution of free surfactant molecules during droplet drying depended on the process and formulation parameters. Enrichment of PS80 at the particle surface was most pronounced after co-spray drying of liquid feedstocks with low suspended fraction at process conditions favouring rapid droplet drying.

Abstract
Many properties of materials, including their dissolution kinetics, hardness, and optical appearance, depend on their structure. Unfortunately, it is often difficult to control the structure of low molecular weight organic compounds that have a high propensity to crystallize if they are formulated from solutions wherein they have a high mobility. This limitation can be overcome by formulating these compounds within small airborne drops that rapidly dry, thereby limiting the time molecules have to arrange into the thermodynamically most stable phase. Such drops can be formed with a surface acoustic wave (SAW)-based spray-drier. In this paper, we demonstrate that the structure of a model low molecular weight compound relevant to applications in pharmacology and food, succinic acid, can be readily controlled with the supersaturation rate. Succinic acid particles preserve the metastable structure over at least 3 months if the initial succinic acid concentration is below 2% of its saturation concentration such that the supersaturation rate is high. We demonstrate that also the stability of the metastable phases against their transformation into the most stable phase increases with decreasing initial solute concentration and hence with increasing supersaturation rate of the spray-dried solution. These insights open up new opportunities to control the crystal structure and therefore properties of low molecular weight compounds that have a high propensity to crystallize.

Int J Pharm 2023; 634:122641. [PMID: 36709012 DOI: 10.1016/j.ijpharm.2023.122641] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 01/17/2023] [Accepted: 01/20/2023] [Indexed: 01/26/2023]
Abstract
Nisin ZP is an antimicrobial peptide (AMP) produced by the bacterium Lactococcus lactis, and we have previously demonstrated anticancer activity in NSCLC (A549) cells. In this study, we formulated a nisin ZP dry powder (NZSD) using a spray dryer to facilitate inhaled delivery for the treatment of NSCLC. Nisin ZP was spray-dried with mannitol, l-leucine, and trehalose in a ratio of 75:15:10 using Büchi mini spray-dryer B-290 in different drug loadings (10, 20, and 30% w/w). NZSD powder revealed a good powder yield of >55% w/w with ≤3 % w/w moisture content and high nisin ZP drug loading for all the peptide ratios. The NZSD powder particles were irregularly shaped with corrugated morphology. The presence of an endothermic peak in DSC thermograms and attenuated crystalline peaks in PXRD diffractograms confirmed the semi-crystalline powder nature of NZSD. The anticancer activity of nisin ZP was maintained after fabricating it into NZSD powder and showed a similar inhibitory concentration to free nisin ZP. Stability studies indicated that NZSD powders were stable for three months at 4 and 25 ℃ with more than 90% drug content and semi-crystalline nature, as confirmed by DSC and PXRD. Aerosolization studies performed using NGI indicated an aerodynamic diameter (MMAD) within the desired range (1-5 µm) and a high fine particle fraction (FPF > 75%) for all peptide ratios, suggesting powder deposition in the lung's respiratory airways. In conclusion, a dry powder of nisin ZP was formulated using a spray dryer with enhanced storage stability and suitable for inhaled delivery.

Abstract
Inflammation is a key pathological driver in cystic fibrosis (CF). Current therapies are ineffective in treating and preventing the escalation of inflammatory events often exacerbated by superimposed infection. In this work, we propose a novel treatment based on the pulmonary administration of anakinra, a non-glycosylated recombinant form of IL-1Ra. An inhalable dry powder of anakinra was successfully developed to meet the specific needs of lung drug delivery. The new formulation was investigated in vitro for aerodynamic performances and activity and in vivo for its pharmacological profile, including the pharmacokinetics, treatment schedule, antimicrobial and anti-inflammatory activity and systemic toxicity. The protein was structurally preserved inside the formulation and retained its pharmacological activity in vitro immediately after preparation and over time when stored at ambient conditions. Anakinra when delivered to the lungs showed an improved and extended therapeutic efficacy in CF models in vivo as well as higher potency compared to systemic delivery. Peripheral side effects were significantly reduced and correlated with lower serum levels compared to systemic treatment. These findings provide proof-of-concept demonstration for anakinra repurposing in CF through the pulmonary route.

Abstract
PURPOSE Spray-freeze drying (SFD) incorporating diverse carbohydrates and leucine was employed to obtain dried nanosuspension of cefixime with improved dissolution profile, good dispersibility, and excellent inhalation performance. METHODS Nanoprecipitation was utilized to prepare nanoparticles (NPs). Nanosuspensions of cefixime were solidified via SFD to access inhalable microparticles. The aerosolization efficiencies were evaluated through twin stage impinger (TSI). Laser light scattering and scanning electron microscopy (SEM) provided assistance to determine the particle size/size distribution and morphology, respectively. Amorphous/ crystalline states of materials were examined via differential scanning calorimetry (DSC) and X-ray diffraction (XRD). Release profiles of candidate preparations were evaluated. RESULTS The fine particle fraction (FPF) ranged from 18.96 ± 0.76 to 79.28 ± 0.45%. The highest value resulted from trehalose with NP/carrier ratio of 1:1 and leucine 20%. The particle size varied from 5.24 ± 0.97 to 10.17 ± 1.01 μm. The most and the least size distribution were achieved in mannitol and trehalose containing formulations, respectively. The majority of samples demonstrated ideally spherical morphology with diverse degrees of porosity and without needle-shaped structure. Percentages of release in F7 and F8 were 89.33 ± 0.88% and 93.54 ± 1.02%, respectively, via first 10 min. CONCLUSION SFD of nanosuspensions can be established as a platform for the pulmonary delivery of poorly water-soluble molecules of cefixime. Trehalose and raffinose with a lower ratio of NP to the carrier and higher level of leucine could be introduced as favorable formulations for further respiratory delivery of cefixime.

Abstract
The development of small interfering RNA (siRNA) formulation for pulmonary delivery is a key to the clinical translation of siRNA therapeutics for the treatment of respiratory diseases. Most inhalable siRNA powder formulations published to date were limited by the siRNA content which was often too low to be clinically relevant. This study aimed to prepare inhalable siRNA powder formulations that contained high siRNA loading of over 6% w/w by spray drying, with human serum albumin (HSA) investigated as a dispersion enhancer to improve the aerosol performance. The effect of siRNA, HSA and solute concentrations in the formulations were evaluated systemically using factorial analyses. All the spray dried siRNA powders exhibited excellent aerosol performance with fine particle fraction (FPF) consistently over 50% in all the formulations. An enrichment of HSA on the particle surface was observed. Surface corrugation was more prominent as HSA composition increased. Importantly, the bioactivity of siRNA was successfully preserved upon spray drying as demonstrated in the in vitro transfection study, and up to 78% of intact siRNA retained in the spray dried powder. Overall, HSA is an effective dispersion enhancer and spray drying is an appropriate technique to produce inhalable dry powder with high siRNA loading for further investigation.

Abstract
Pulmonary delivery of small interfering RNAs (siRNAs) has shown promising results for the treatment of lung diseases with gene disorders. The aim of this work was to evaluate the effect of processing-induced thermal and shear stresses during the spray drying process on the solid-state properties, the chemical integrity and the bioactivity of spray-dried siRNA powder intended for inhalation. To this end, inhalable siRNA dry powders composed of EGFP-siRNA and mannitol were prepared by using a lab-scale spray drier. Scanning electron microscopy (SEM), laser diffraction, and X-ray powder diffraction (XRPD) were used to characterize the solid-state properties of the spray-dried siRNA-mannitol powders. High performance liquid chromatography (HPLC) and flow cytometry were exploited to assess the chemical stability and cellular transfection efficiency of siRNA formulations, respectively. The results showed that the spray-dried particles changed from spherical to irregular shape with an increase in the inlet temperature. The high inlet temperature and intensive atomization conditions resulted in more agglomerates in the spray-dried particles. XRPD analysis indicated that the presence of siRNA affected the polymorphic form of mannitol in the spray-dried powder. Compromised chemical stability and cell transfection efficiency of siRNA were observed with an increase in the thermal stress and shear stress during the spray drying process. The chemical stability of siRNA in liquid state was more prone to thermal stress when compared to the stability in the solid-state. In conclusion, stable siRNA based particles for inhalation purposes could be produced using the spray drying technology.

Abstract
In chronic intestinal diseases like inflammatory bowel disease, parenteral administration of biopharmaceuticals is associated with numerous disadvantages including immune reactions, infections, low patient compliance, and toxicity caused by high systemic bioavailability. One alternative that can potentially overcome these limitations is oral administration of biopharmaceuticals, where the local delivery will reduce the systemic exposure and furthermore the manufacturing costs will be lower. However, the development of oral dosage forms that deliver the biologically active form to the intestines is one of the greatest challenges for pharmaceutical technologists due to the sensitive nature of biopharmaceuticals. The present article discusses the various drug delivery technologies used to produce orally administered solid dosage forms of biopharmaceuticals with an emphasis on colon-targeted delivery. Solid oral dosage compositions containing different types of colon-targeting biopharmaceuticals are compiled followed by a review of currently applied and emerging drying technologies for biopharmaceuticals. The different drying technologies are compared in terms of their advantages, limitations, costs and their effect on product stability.

Abstract
Spray freeze drying is an attractive technology to produce powder formulation for inhalation. It can be used to generate large porous particles which tend to aerosolize efficiently and do not aggregate readily. It also avoids material to be exposed to elevated temperature. In this study, we reported the use of two-fluid nozzle to produce spray freeze dried powder of small interfering RNA (siRNA). The effect of atomization gas flow rate and liquid feed rate were inspected initially using herring sperm DNA (hsDNA) as nucleic acid model. The atomization gas flow rate was found to have a major impact on the aerosol properties. The higher the atomization gas flow rate, the smaller the particle size, the higher the fine particle fraction (FPF). In contrast, the liquid feed rate had very minor effect. Subsequently, spray freeze dried siRNA powder was produced at various atomization gas flow rates. The particles produced were highly porous as examined with the scanning electron microscopy, and the structural integrity of the siRNA was demonstrated with gel electrophoresis. The gene-silencing effect of the siRNA was also successfully preserved in vitro. The best performing siRNA formulation was prepared at the highest atomization gas flow rate investigated with a moderate FPF of 30%. However, this was significantly lower than that obtained with the corresponding hsDNA counterparts (FPF ∼57%). A direct comparison between the hsDNA and siRNA formulations revealed that the former exhibited a lower density, hence a smaller aerodynamic diameter despite similar geometric size.

Abstract
The comparison of spray drying versus hot melt extrusion (HME) in order to formulate amorphous solid dispersions has been widely studied. However, to the best of our knowledge, the use of both techniques to form cocrystals within a carrier excipient has not previously been compared. The combination of ibuprofen (IBU) and isonicotinamide (INA) in a 1:1 M ratio was used as a model cocrystal. A range of pharmaceutical excipients was selected for processing - mannitol, xylitol, Soluplus and PVP K15. The ratio of cocrystal components to excipient was altered to assess the ratios at which cocrystal formation occurs during spray drying and HME. Hansen Solubility Parameter (HSP) and the difference in HSP between the cocrystal and excipient (ΔHSP) was employed as a tool to predict cocrystal formation. During spray drying, when the difference in HSP between the cocrystal and the excipient was large, as in the case of mannitol (ΔHSP of 18.3 MPa0.5), a large amount of excipient (up to 50%) could be incorporated without altering the integrity of the cocrystal, whereas for Soluplus and PVP K15, where the ΔHSP was 2.1 and 1.6 MPa0.5 respectively, the IBU:INA cocrystal alone was only formed at a very low weight ratio of excipient, i.e. cocrystal:excipient 90:10. Remarkably different results were obtained in HME. In the case of Soluplus and PVP K15, a mixture of cocrystal with single components (IBU and INA) was obtained even when only 10% excipient was included. In conclusion, in order to reduce the number of unit operations required to produce a final pharmaceutical product, spray drying showed higher feasibility over HME to produce cocrystals within a carrier excipient.

Abstract
Tuberculosis (TB) is a global disease that is becoming more difficult to treat due to the emergence of multidrug resistant (MDR) Mycobacterium tuberculosis. Inhalable antimicrobial peptides (AMPs) are potentially useful alternative anti-TB agents because they can overcome resistance against classical antibiotics, reduce systemic adverse effects, and achieve local targeting. The aims of the current study were to produce inhalable dry powders containing d-enantiomeric AMPs (D-LAK120-HP13 and D-LAK120-A) and evaluate their solid state properties, aerosol performance, and structural conformation. These two peptides were spray dried with mannitol as a bulking agent at three mass ratios (peptide:mannitol 1:99, 1:49, and 1:24) from aqueous solutions. The resultant particles were spherical, with those containing D-LAK120-HP13 being more corrugated than those with D-LAK120-A. The median volumetric diameter of the particles was approximately 3μm. The residual water content of all powders were <3% w/w and crystalline, due to the low hygroscopicity and crystallinity of mannitol, respectively. The mannitol changed from a mixture of alpha- and beta-forms to delta form with an increasing proportion of AMP in the formulation. The emitted fraction and fine particle fraction of the powders when dispersed from an Osmohaler(®) at 90L/min were about 80% and 50-60% of the loaded dose, respectively, indicating good aerosol performance. Circular dichroism data showed that D-LAK120-HP13 dissolved in Tris buffer at pH 7.15 was of a disordered conformation. In contrast, D-LAK120-A showed greater α-helical conformation. Since the conformations of the AMPs were comparable to the controls (unprocessed peptides), the spray drying process did not substantially affect their secondary structures. In conclusion, spray dried powders containing d-enantiomeric AMPs with preserved secondary molecular structures and good aerosol performance could be successfully produced. They may potentially be used for treating MDR-TB when delivered by inhalation.

Abstract
Here we present a single-step all-aqueous approach to encapsulate biomolecules such as enzymes and proteins into stable microreactors. Key in this method is the use of spray-drying of the biomolecules of interest in combination with oppositely charged polyelectrolytes and mannitol as the sacrificial template. Remarkably, upon spray-drying in the presence of polyelectrolyte, mannitol crystallization is suppressed and the obtained amorphous mannitol offers enhanced preservation of the biomolecules' activity. Moreover, the use of mannitol allows the formation of nanopores within the microparticles upon rehydration of the microparticles in aqueous medium and subsequent dissolution of the mannitol. The oppositely charged polyelectrolytes provide a polymeric framework which stabilizes the microparticles upon rehydration. The versatility of this approach is demonstrated using horseradish peroxidase as the model enzyme and ovalbumin as the model antigen.

Abstract
The purpose of this project was to investigate the polymorphic variation of spray-dried mannitol model formulations as a function of particle size. Spray-dried powders with varying mannitol polymorphs were produced by adjusting process parameters, using co-solvent and adding a model protein (lysozyme). The obtained dry powders were dispersed into different size fractions using a Next Generation Pharmaceutical Impactor. The mannitol polymorphs in the different size fractions were analyzed using X-ray powder diffraction (XRPD), Fourier transform near infrared (FT-NIR) and Raman spectroscopy. Chemometrics was applied to interpret the FT-NIR and Raman spectra. Different spray-dried mannitol systems were established in this study, which contain mixtures of α- and β-mannitol. The XRPD, FT-NIR and Raman studies showed that the use of ethanol as a co-solvent increased the amount of α-mannitol in the smaller particles. The addition of low levels of lysozyme resulted in more α-mannitol in the smaller particles, while an increased content of lysozyme in spray-dried mannitol system resulted in more β-mannitol in the smaller particle size fraction. In conclusion spray-drying of mannitol based formulations can result in variation in the solid state composition of mannitol as a function of particle size. This finding may be clinically relevant and underlines the need for proper process control of inhalable dry powder produced by spray-drying.

Abstract
In this research mannitol particles were prepared by recrystallisation using non-solvent precipitation technique to investigate the effect of engineered carrier particles on their physicochemical properties and the in vitro deposition profiles of a model drug (salbutamol sulphate (SS)) from a dry powder inhaler (DPI). To this end, mannitol aqueous solution (15%, w/v) was added to different ratios of ethanol:water (100:0, 95:5, 90:10 and 85:15) to obtain mannitol particles. These crystallised mannitol particles were analysed in terms of micromeritic properties, morphology, DSC, FT-IR, and in vitro fine particle fraction (FPF) and emitted dose (ED) of SS. The results showed that the elongation ratio of all the recrystallised mannitol batches was higher than the original material giving them a needle-shaped morphology. Salbutamol sulphate deposition profiles from DPI formulation containing recrystallised needle-shaped mannitol showed enhanced performance and better delivery to the lower MSLI stages. The FPF increased from 15.4+/-1.1 to 45.8+/-0.7% when the commercial mannitol was replaced by mannitol crystallised from ethanol:water (90:10). This improvement could be due to the presence of elongated mannitol crystals in formulation blends. Solid state characterisation of engineered mannitol showed that the commercial mannitol was beta-form, mannitol recrystallised from ethanol:water (85:15) was alpha-form and that samples recrystallised in presence of pure ethanol or other ratios of ethanol:water (95:5 and 90:10) were the mixtures of alpha-, beta- and delta-forms. Multi-solvent recrystallisation technique was proved to have potential to produce mannitol crystals suitable for enhanced aerosolisation efficiency. Comparing different crystallised mannitol formulations showed that the final form (the type of polymorph) of the crystallised mannitol does not have a substantial effect on salbutamol sulphate aerosolisation performance.
