Abstract
Leishmania is one of the most common diseases between human and animals, caused by Leishmania infantum parasite. Here, we have developed an ultra-selective turn-on fluorescent probe based on an aptamer and Chitosan-CD nanocomposite. The CD used in this study were synthesized using Quercus cap extract and a microwave-assisted approach. The Chitosan-CD nanocomposite was optimized using several microscopic and spectroscopic techniques to possess a bright fluorescence emission before adding aptamer and totally quenched fluorescence after addition of aptamer. The designed probe was proficient in the detection and quantification Leishmania infantum parasite by selective targeting of poly(A) binding protein (PABP) on the surface of the parasite. The designed fluorescent biosensor with high sensitivity, excellent selectivity, and a limit of detection (LOD) of 94 cells/mL of the Leishmania infantum parasite as well as a linear response in the ranges of 188-750 cells/mL and 3000-6000 cells/mL (R2 ≥ 0.98 for both linear ranges). Additionally, the selectivity of the designed probe was evaluated in the presence of different pathogenic species such as Trypanosoma brucei parasite and Staphylococcus aureus bacteria, as well as LiIF2α and LiP2a and BSA proteins as interference substances. The results of this study shows that using Chitosan-CD nanocomposite is a great strategy for developing selective turn-on probes with extraordinary accuracy and sensitivity in identifying Leishmania infantum parasite, especially in the early stages of the disease, and it is promising for the future clinical applications.

Rapid and naked-eye colorimetric detection of ultra trace sumatriptan in drinking water, saliva, and human urine samples based on the aggregation of gold nanoparticles. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 302:123039.

Abstract
In this study, the determination of sumatriptan (SUM) was performed using a simple, rapid, and precise colorimetric method based on the surface plasmon resonance (SPR) feature of gold nanoparticles (AuNPs). By adding SUM, the aggregation was observed in AuNPs with red-to-blue color shifts. The size distribution of NPs was estimated before and after adding SUM via dynamic light scattering (DLS), which was found to be 15.34 and 97.45 nm, respectively. Characterization of AuNPs, SUM, and AuNPs in combination with SUM was investigated using transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). Examining the effect of pH, the volume of buffer, the concentration of AuNPs, interaction time, and ionic strength revealed that their optimal values were 6, 100 μL, 5 μM, 14 min, and 12 μg L-1, respectively. The suggested method was able to determine the amount of SUM in a linear range of 10 to 250 μg L-1 with a limit of detection (LOD) and limit of quantification (LOQ) of 0.392 and 1.03 μg L-1, respectively. This approach was successfully applied to determine SUM in drinking water, saliva, and human urine samples with relative standard deviations (RSD) lower than 0.03%, 0.3%, and 1.0%, respectively.

Abstract
Controlling the wound exudates accompanied by microbial wound infections has still remained as one the most challenging clinical issues. Herein, a chitosan/gelatin/polyvinyl alcohol xerogel film containing Thymus pubescens essential oil is fabricated for antimicrobial wound dressing application. The chemical and physical characteristics of the devised formulation is characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, atomic force microscope, and tensile tests. Moreover, swelling capability, water vapour transmission rate, water contact angle, solubility, moisture content, and release properties are also studied. The antimicrobial and antibiofilm tests are performed using the broth microdilution and XTT assay, respectively. The produced formulation shows excellent antimicrobial efficacy against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Candida species. It is also demonstrated that the obtained film can reduce (∼80 %) Candida albicans biofilm formation, and its biocompatibility is confirmed with MTT (∼100 %) and hemolysis tests. The antimicrobial activity can be correlated to the microbial membrane attraction for Candida albicans cells, illustrated by flow cytometry. This proposed film with appropriate mechanical strength, high swelling capacity in different pH values (∼200-700 %), controlled release property, and antimicrobial and antioxidant activities as well as biocompatibility can be used as a promising candidate for antimicrobial wound dressing applications.

Encapsulation of Zataria multiflora essential oil in polyvinyl alcohol/chitosan/gelatin thermo-responsive hydrogel: Synthesis, physico-chemical properties, and biological investigations. Int J Biol Macromol 2023:125073. [PMID: 37245771 DOI: 10.1016/j.ijbiomac.2023.125073] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 04/25/2023] [Accepted: 05/22/2023] [Indexed: 05/30/2023]
Abstract
Zataria multiflora essential oil is a natural volatile plant product whose therapeutic applications require a delivery platform. Biomaterial-based hydrogels have been extensively used in biomedical applications, and they are promising platforms to encapsulate essential oils. Among different hydrogels, intelligent hydrogels have recently attracted many interests because of their response to environmental stimuli such as temperature. Herein, Zataria multiflora essential oil is encapsulated in a polyvinyl alcohol/chitosan/gelatin hydrogel as a positive thermo-responsive and antifungal platform. According to the optical microscopic image, the encapsulated spherical essential oil droplets reveal a mean size of 1.10 ± 0.64 μm, which are in consistent with the SEM imaging results. Encapsulation efficacy and loading capacity are 98.66 % and 12.98 %, respectively. These results confirm the successful efficient encapsulation of the Zataria multiflora essential oil within the hydrogel. The chemical compositions of the Zataria multiflora essential oil and the fabricated hydrogel are analyzed by gas chromatography-mass spectroscopy (GC-MS) and Fourier transform infrared (FTIR) techniques. It is found that thymol (44.30 %) and γ-terpinene (22.62 %) are the main constituents of the Zataria multiflora essential oil. The produced hydrogel inhibits the metabolic activity of Candida albicans biofilms (~60-80 %), which can be related to the antifungal activity of the essential oil constituents and chitosan. Based on the rheological results, the produced thermo-responsive hydrogel shows a gel-sol viscoelastic transition at a temperature of 24.5 °C. This transition leads to a facile release of the loaded essential oil. The release test depicts that about 30 % of Zataria multiflora essential oil is released during the first 16 min. In addition, 2, 5-diphenyl-2H-tetrazolium bromide (MTT) assay demonstrates that the designed thermo-sensitive formulation is biocompatible with high cell viability (over 96 %). The fabricated hydrogel can be deemed as a potential intelligent drug delivery platform for controlling cutaneous candidiasis due to antifungal effectiveness and less toxicity, which can be a promising alternative to traditional drug delivery systems.

Abstract
Sumatriptan succinate and prochlorperazine maleate are a clinically proven combination for treating migraine and associated nausea and vomiting. Classical oral dosage forms are not frequently workable in migraine because of the associated nausea/vomiting, and no effective fixed dose combination is available. Thus, the aim of the study was to optimize a combined sumatriptan-prochlorperazine orodispersible film for rapid release of drugs. Orodispersible films were prepared by solvent casting method using varied amounts of polyvinyl alcohol and glycerol as film former and plasticizer, respectively, along with fixed levels of other ingredients employing central composite design. The optimum film (VF) demonstrated disintegration and total dispersion times as 21 s and 2.3 min, respectively. Tensile strength and Young's modulus were 8.86 ± 0.37 MPa and 24.15 ± 0.07 MPa, respectively. The in vitro T80% of both drugs from the ODF was achieved within 4 min. The film was palatable and disintegrated in 2 min in buccal cavity of human volunteers. Permeation study through goat mucosa demonstrated 100% permeation of both drugs within 15 min. X-Ray diffraction and differential scanning calorimetry supported drugs being amorphous and Fourier transform infrared demonstrated drug-excipient compatibility in optimized film. A judicious combination of sumatriptan succinate and prochlorperazine maleate could be prepared in orodispersible films for the possible relief of migraine.

Abstract
BACKGROUND Sumatriptan is a routine medication in the treatment of migraine and cluster headache that is generally given by oral or parental routes. However, a substantial proportion of patients suffer severe side effects. The aim of this study was to investigate the physicochemical characterization and pharmacokinetic parameters of a novel delivery system for sumatriptan succinate (SS) using nanoliposomes (NLs) coated by chitosan (CCLs) to optimize the formulations to enhance its bioavailability. METHODS The new formulation was used to minimize drug particle size and extend its release and bioavailability. The mean particle size and entrapment efficiency for NLs and CCls were optimized and the formulations with better characteristics were chosen for in vivo studies. The concentration-time profile of intravenous SS, intranasal SS, SS-NLs, and CCLs were examined in a rabbit model. RESULTS The results demonstrated that CCLs were absorbed more rapidly from nasal drops containing chitosan compared to those of SS and SS-NLs as indicated by a shorter tmax, and a higher Cmax in both states. A comparison of the AUC (0-240 min) values revealed that chitosan improved the extent of SS absorption for CCLs formulation. The results of the present study indicated that loading SS into the liposome and coating with chitosan improves drug absorption and a large amount of the drug can be efficiently delivered into the systemic circulation. CONCLUSION The liposomal and chitosan formulations of SS had better kinetic behavior than the soluble form in the animal model.

Abstract
The current research article focused on formulating an easily applied, water-based buccal film loaded with the antiepileptic drug, lamotrigine (LTG). The designed film can be comfortably administered by epileptic patients to ensure a controllable therapeutic efficacy against seizures. The solubility of LTG in water was significantly improved by micellar solubilization. Upon testing several surfactants, three of them (Synperonic PE/P84, Brij L23, and Brij 78) achieved maximum possible solubility for LTG and were characterized for their micellar size, cloud point, and % transmittance. Selected micellar systems were incorporated within a buccal film prepared using solvent casting method based on either gelatin or polyvinylpyrrolidone (3%w/v) with 1.5%w/v propylene glycol as a plasticizer. Different micellar films were characterized for their physicochemical characteristics, swelling index, folding endurance, drug content uniformity, and in vitro LTG release. From the tested formulations, one formulation; LTG-BF1 (in which Brij 78 was used for the micellar solubilization and gelatin as the matrix former), was selected as the optimum and extensively studied for mucoadhesion, ex vivo permeation studies by Franz diffusion cells and confocal laser scanning microscopy. Results showed superior enhanced permeation of micellar film. LTG-BF1 was evaluated for the in vivo performance using rats. Status epilepticus was induced in rats by injecting Pentylenetetrazol (PTZ) i.p. at an initial dose of 30 mg/kg, followed by 10 mg/kg every10 min till 60 min. A group of rats receiving the designed buccal formulation (20 mg/kg) was compared with a group receiving the same dose of the oral market product and the normal control and PTZ groups. Rats receiving LTG-BF1 recorded reduced seizure scores at all stages, longer latency time, and higher threshold PTZ dose compared to PTZ and market product groups. In addition, LTG-BF1 reduced brain concentrations of TNF-α and TGF-β with an elevation of EAAT2 and GABA brain contents compared to PTZ and market product groups and ameliorated neuronal damage. In conclusion, LTG-loaded buccal micellar film proved a superior antiepileptic effect in PTZ induced acute epileptic model.

Abstract
In this study, buccal mucoadhesive tablets of meloxicam were formulated for drug delivery as an alternative route. Direct compression method was applied for the preparation of tablets. Also, different polymers, including hydroxypropyl methyl cellulose (HPMC) 1000, 4000, and 10000, as well as carbopol 934p and carbopol 971p were used as the mucoadhesive polymer and retardant polymer. Thirteen formulations were investigated with various concentrations of polymers. The physicochemical characteristics, in-vitro drug release, swelling index, and taste modification of tablets were evaluated. Also, Carr’s index and Hausner ratio were studied. In addition, zero-order, first-order, and Higuchi kinetics were investigated and the results showed that the highest correlation coefficient (R2) is related to zero-order kinetic for formulations B2 and B3. Furthermore, the highest R2 is related to Higuchi kinetic for formulation C3. Formulation B2 showed the maximum release of 99% in 12 h. The results demonstrated that Formulation B2 can be considered as a proper buccal mucoadhesive tablet of meloxicam with desired property.

Abstract
Preterm labor is the main cause of death and serious illness of both infants and pregnant women in Africa and worldwide. Parenteral and oral salbutamol sulfate as a B2 antagonist has been used for the treatment of preterm labor. The study aims are to formulate salbutamol sulfate non-invasive vaginal bioadhesive tablets to avoid the side effects of conventional formulations. Full factorial design 41 ×31 ×21 was used for the preparation of 24 vaginal bioadhesive tablet formulations. The independent factors were polymer type (Carbopol 934, HPMC 4000, HEC, and PEG 6000), polymer to drug ratio (1:1, 2:1, and 3:1), and diluent (lactose and mannitol). Vaginal bioadhesive tablets were evaluated for residence time and time required for release 50% of salbutamol sulfate T50% as dependent variables. The formulations were evaluated in terms of drug content, mass variation, hardness, friability, swelling index, residence time, and in-vitro drug release. Results revealed that polymer and diluent types are the most significant factors in both residence time and T50%. A strong positive correlation (0.91) between in-vitro and ex-vivo permeation was observed, which predict the best in-vivo performance of salbutamol vaginal bioadhesive tablet. Thus, salbutamol sulfate vaginal bioadhesive tablets could be a successful remedy for preterm labor.

Abstract
The aim of this study was to formulate an easily-administered, safe and effective dosage form loaded with meclizine for treatment of chemotherapy-induced nausea and vomiting (CINV) through the buccal route. CINV comprises bothersome side effects accompanying cytotoxic drugs administration in cancer patients. Meclizine was loaded in chitosan-pectin nanoparticles which were further incorporated within a buccal film. Different formulations were prepared based on a 21.31 full factorial study using Design Expert®8. The optimum formulation possessed favorable characters regarding its particle size (129 nm), entrapment efficiency (90%) and release profile. Moreover, its permeation efficiency through sheep buccal mucosa was assessed via Franz cell diffusion and confocal laser microscopy methods. Enhanced permeation was achieved compared with the free drug form. In-vivo performance was assessed using cyclophosphamide induced emesis. The proposed formulation exerted significant relief of the measured responses (reduced body weight and motor coordination, elevated emesis, anorexia, proinflammatory mediators and neurotransmitters that were also associated with scattered degenerated neurons and glial cells). The developed formulation ameliorated all behavioral, biochemical and histopathological changes induced by cyclophosphamide. The obtained data were promising suggesting that our bioadhesive formulation can offer an auspicious medication for treating distressing symptoms associated with chemotherapy for cancer patients.

Abstract
Mucoadhesive delivery systems have attracted remarkable interest recently, especially for their potential to prolong dosage form resident times at sites of application such as the vagina or nasal cavity, thereby improving convenience and compliance as a result of less frequent dosage. Mucoadhesive capabilities need to be routinely quantified during the development of these systems. This is however logistically challenging due to difficulties in obtaining and preparing viable mucosa tissues for experiments. Utilizing artificial membranes as a suitable alternative for quicker and easier analyses of mucoadhesion of these systems is currently being explored. In this study, the mucoadhesive interactions between progesterone-loaded fibers (with varying carboxymethyl cellulose (CMC) content) and either artificial (cellulose acetate) or mucosa membranes are investigated by texture analysis and results across models are compared. Mucoadhesion to artificial membrane was about 10 times that of mucosa, though statistically significant ( p = 0.027) association between the 2 data sets was observed. Furthermore, a hypothesis relating fiber-mucosa interfacial roughness (and unfilled void spaces on mucosa) to mucoadhesion, deduced from some classical mucoadhesion theories, was tested to determine its validity. Points of interaction between the fiber and mucosa membrane were examined using atomic force microscopy (AFM) to determine the depths of interpenetration and unfilled voids/roughness, features crucial to mucoadhesion according to the diffusion and mechanical theories of mucoadhesion. A Kendall's tau and Goodman-Kruskal's gamma tests established a monotonic relationship between detaching forces and roughness, significant with p-values of 0.014 and 0.027, respectively. A similar relationship between CMC concentration and interfacial roughness was also confirmed. We conclude that AFM analysis of surface geometry following mucoadhesion can be explored for quantifying mucoadhesion as data from interfacial images correlates significantly with corresponding detaching forces, a well-established function of mucoadhesion.

Abstract
Most therapeutic proteins are classified as class III drugs according to the Biopharmaceutical Classification System means that the low permeability across the intestinal epithelium is the rate-limited step for their oral absorption. Cationic chitosan nanoparticles have been found to open the tight junctions between epithelial cells. On the other hand, bioadhesive delivery devices could prolong the gastrointestinal residence time. In the present study, we developed a novel nano-reservoir bioadhesive tablets that combining the advantages of cationic nanoparticles and bioadhesive delivery devices anticipated achieving effective transport of sufficient protein drugs across the intestinal epithelium. The nano-reservoir in bioadhesive tablets was composed of chitosan nanoparticles (CS-NPs) loading a model protein drug bovine serum albumin (BSA). The formula of bioadhesive tablets was optimized by using rotatable central composite design and response surface methodology. The nano-reservoir, BSA-loaded CS-NPs, had an average particle diameter of 312.5 ± 12.89 nm and zeta-potential value of 26.76 ± 3.56 mV. Carboxymethyl chitosan added to the formula significantly ameliorated the tight junction damage of the Caco-2 cell monolayer induced by CS-NPs, meanwhile maintained the high transport efficiency of BSA. Permeability study exhibited that these nano-reservoir bioadhesive tablets combining the advantages of cationic nanoparticles and bioadhesive tablets significantly enhanced BSA transport through rabbit small intestine in comparison with either conventional bioadhesive tablets or CS-NPs. Therefore, these nano-reservoir bioadhesive tablets provided a great potential dosage form design for the oral delivery of protein drugs.

Abstract
We investigated the structure of the binary mixture of Pluronic F-127 (PL F-127) and Pluronic L-81 (PL L-81), as hydrogels for sumatriptan delivery and investigated the mixture possible use via subcutaneous route for future applications as a long-acting antimigraine formulation. We studied the drug-micelle interaction by dynamic light scattering and differential scanning calorimetry, sol-gel process by rheology, and small-angle X-ray scattering (SAXS). We also employed pharmaceutical formulation aspects by dissolution rate, release profile, and cytotoxicity studies for apoptosis and/or necrosis in fibroblasts (3T3) and neural cells (Neuro 2a). Micellar hydrodynamic diameter studies revealed the formation of binary PL-micelles by association of PL F-127/PL L-81. The mixed micelle and binary hydrogels formation was also verified by only one phase transition temperature for all formulations, even in the presence of sumatriptan. The characterization of the hydrogel supramolecular organization by SAXS, rheology studies, and in vitro dissolution/release results showed a probable relationship between the transition of the lamellar to the hexagonal phase and the lower release constant values observed, indicating that PL L-81 participates in micelle-hydrogel formation and aggregation processes. Furthermore, the reduced cytotoxicity (annexin V-fluorescein isothiocyanate positive staining), with minor PL L-81 concentration, points to its potential use for the development of binary PL-systems containing sumatriptan capable of modulating the gelation process. This use may employ the minimum PL concentration and be interesting for pharmaceutical applications, particularly for migraine treatment.

Abstract
BACKGROUND Here we report the prescription patterns by drug type, age, and sex of patients at a large academic pediatric hospital. Because there are few guidelines based on outcome studies in pediatric migraine, physician treatment approaches in children vary. METHODS Using the i2b2 query tool, we determined that over an approximately 4 year period, 4839 patients between the ages of 2 and 17 years were observed at Boston Children's Hospital for migraine with or without aura, 59% women and 41% men. RESULTS The most common medications prescribed to this population were sumatriptan, amitriptyline, topiramate, ondansetron, and cyproheptadine. CONCLUSIONS Our findings support recent data regarding choices of medication in the pediatric population and additionally support current studies and future investigation into controlled trials in the pediatric population.

Abstract
Oral transmucosal drug delivery (OTDD) dosage forms have been available since the 1980s. In contrast to the number of actives currently delivered locally to the oral cavity, the number delivered as buccal or sublingual formulations remains relatively low. This is surprising in view of the advantages associated with OTDD, compared with conventional oral drug delivery. This review examines a number of aspects related to OTDD including the anatomy of the oral cavity, models currently used to study OTDD, as well as commercially available formulations and emerging technologies. The limitations of current methodologies to study OTDD are considered as well as recent publications and new approaches which have advanced our understanding of this route of drug delivery.

Abstract
INTRODUCTION Postoperative nausea and vomiting (PONV) is associated with poor patient satisfaction and delayed recovery after general anesthesia. Multiple neurotransmitters are involved in the mediation of PONV but despite the introduction of new antiemetics, no completely effective drug exists for its prevention or treatment. AREAS COVERED This review provides a detailed description of ondansetron's chemistry, pharmacokinetics, pharmacodynamics, toxicity and a brief review of clinical trials involving ondansetron and the management of PONV. We searched reviews, meta-analysis and randomized controlled trials (Medline, Embase and article reference lists). EXPERT OPINION According to current literature, administering ondansetron 4 mg i.v. near the end of surgery provides sufficient protection against PONV in low- and moderate-risk patients, comparable to traditional antiemetics such as antihistamines and droperidol. High-risk patients require a multimodal approach since one quarter of them will not respond to monotherapy. In the future, transdermal formulation or formulations for nasal or buccal delivery will be available. The development of non-racemic mixture consisting of R-ondansetron would enhance the safety profile and probably the efficacy too.

Abstract
Background: Glibenclamide (G) is a popular anti-diabetic drug, belonging to the class of sulfonylurea. The drug is widely used for treating type II diabetes but it undergoes first-pass effect. A novel aspiration in treatment of diabetes, to provide greater therapeutic effect, bypass first pass effect and to improve patient compliance upon administering buccal drug delivery of Glibenclamide (G) have not been tested literally. Hence, the present study was designed to develop the buccal mucoadhesive films of glibenclamide by solvent casting technique; that is by using different polymers such as Hydroxy Propyl Methyl Cellulose 15 cps (HPMC), carbopol (CP), and poly vinyl pyrrolidone. Propylene glycol, which served the purpose of plasticizer as well as penetration enhancer and the backing membrane used was aluminium foil. Materials and Methods: The films were subjected to physicochemical parameters, in-vitro drug release and ex vivo bucco adhesive strength. Results: The satisfactory results were obtained in all prepared formulation and based on the results G14 [HPMC (150 mg) + CP(20 mg) + PVP (30 mg)] was the best one compared to others. The drug release of all formulation follows zero order kinetics by diffusion mechanism of non-fickian diffusion type. Ex vivo, buccal permeation studies by using sheep buccal mucosa and finally stability studies by using human saliva were carried out for the optimized formulation G14.Good correlation was observed between in-vitro and in vivo correlation, thus revealing the ability of the formulation to reproduce the in-vitro release pattern through the in vivo. Conclusion: Glibenclamide muck-adhesive buccal films could be promising one as they, increase bioavailability by bypassing the first pass effect, minimize the dose, reduces the side effects, and improve patient compliance and also glibenclamide might be a right and suitable candidate for oral controlled drug delivery via buccoadhesive films.
