Abstract
Antimicrobial peptides have appeared to be promising candidates for therapeutic purposes due to their broad antimicrobial activity and non-toxicity. Histatin-5 (Hst-5) is a notable salivary antimicrobial peptide that exhibited therapeutic properties in the oral cavity. Oral mucositis is an acute inflammation of the oral cavity, following cancer therapy. The current treatment methods of oral mucositis have low effectiveness. The aim of this study was to design, formulate and characterize a mucoadhesive gel delivery system for Hst-5 usage in the treatment of oral mucositis. Carbopol 934 and hydroxypropyl methylcellulose (HPMC) have been used in the development of a Hst-5 mucoadhesive gel that was optimized by using Box-Behnken design. The optimized formulation was evaluated in-vitro, based on mucoadhesive strength, viscoelasticity, spreadability, release rate, peptide secondary structure analysis, antimicrobial activity, and storage stability. The efficacy of Hst-5 gel was assessed in vivo in a chemotherapy-induced mucositis model. The results showed a sustained release of Hst-5 from the new formulation. Hst-5 gel exerted antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans. The histopathological, immunohistochemical and statistical analysis showed that the Hst-5 gel had wound healing activity in vivo. The findings of this study indicate that the mentioned compound possesses promising potential as a novel and efficient therapeutic agent in managing oral mucositis. Moreover, the results suggest that the compound is commercially feasible for further development and utilization.

Abstract
Diabetes is characterized by chronic hyperglycemia. Although metformin hydrochloride (MHCl)- and glyburide (GLB)-containing conventional tablets are available in the market and used to treat diabetes, orally disintegrating tablets (ODTs) containing the combination of these drugs are not commercially available. Therefore, the aim of this study was to prepare ODTs containing MHCl and GLB by direct-compression (DC-ODTs) and freeze-drying (FD-ODTs) methods. Physical properties of the powder mixture of DC-ODT formulation were determined (Angle of repose: 37.18 ± 1.27°; compressibility index: 20.31 ± 1.06%; Hausner ratio: 1.25 ± 0.03). Its moisture content was 0.3 ± 0.09%. The hardness values and the disintegration times for DC-ODTs and FD-ODTs were 221.60 ± 40.82 and 66.54 ± 2.68 N, and 80 and 30 s, respectively. Friability values were 0.24% for DC-ODTs and 0.38% for FD-ODTs. In uniformity-of-mass for single-dose-preparations test, the average weight was 684.38 ± 1.97 mg for DC-ODTs and 342.93 ± 2.4 mg for FD-ODTs, with less than 5% deviation for all 20 tablets. Water-absorption ratio for DC-ODTs was 1.30 ± 0.05. More than 90% of MHCl and GLB were dissolved within 5 min in both DC-ODTs and FD-ODTs. Although Caco-2 permeability of MHCl was influenced by the ODTs, GLB permeability was not. These results indicated that MHCl- and GLB-containing ODTs may be used as promising formulations for the treatment of diabetes.

Abstract
Enterovirus 71 (EV71) is a pathogenic factor of severe hand, foot, and mouth disease (HFMD). No vaccine or specific treatment is currently available for EV71 infection. Hence, we developed a buccal mucoadhesive gel containing matrine to protect against HFMD. Mucoadhesive gels were prepared by Carbopol 974P and were combined with Carbopol 971P, sodium carboxymethyl cellulose (CMC-Na), or hydroxypropylmethy cellulose (HPMC K100M). The formulations were characterized in terms of tensile testing and continuous flow techniques for mucoadhesion. The rheological studies and in vitro drug release characteristics were also investigated. The results showed that combinations of two polymers significantly improved mucoadhesion, especially Carbopol 974P blended with HPMC. Carbopol 974P to HPMC blend ratios of 1:1 and 2:1 induced better mucoadhesion in the tensile test and continuous flow method, respectively. The most sustained release was obtained at a Carbopol 974P to HPMC ratio of 2.5:1. A predominantly non-Fickian diffusion release mechanism was obtained. The gel containing 2.5% Carbopol 974P combined with 1% HPMC showed good mucoadhesion properties and sustained drug release.

Abstract
Owing to the ease of the administration, the oral cavity is an attractive site for the delivery of drugs. The main difficulty for administration via the buccal route is an effective physiological removal mechanism of the oral cavity that takes way the formulation from the buccal site and decreases the bioavailability of drugs. The use of mucoadhesive polymers in buccal drug delivery shows assessing buccal drug permeation and absorption, however some studies bring an in vivo performance. This review points to the use of polymers in the manufacture of drug delivery systems (hydrogels, films and tablets) and shows the results of their in vivo performance tests.

Abstract
The aim of the present study was to formulate and evaluate in situ gelling syringeable nanoemulgels (NEGs) of ketoprofen for periodontal delivery. Application of 3-factor 3-level design was employed using the Box-Behnken experimental design for the optimization of nanoemulsion using three independent variables such as percent concentration (v/v) of oil (X1), S mix (mixture of surfactant and cosurfactant) (X2) and water (X3); while the particle size (nm) (Y1), polydispersity index (Y2) and zeta potential (mV) (Y3) were used as dependent variables. The NEG was evaluated based on their drug content, pH measurement, mucoadhesion on the goat buccal mucosa, syringeability and inverted sol-gel transition temperature. The drug release data were analyzed for curve fitting based on the Korsmeyer-Peppas law, and the n-values of optimized A5 and A8 formulations were found 0.3721 and 0.3932, respectively, confirmed that both the formulations followed pseudo Fickian diffusion (n < 0.43). The formulation A8 with the optimal drug release was identified as the best NEG formulation. Results of rheological, mucoadhesion and syringeability studies showed the suitability of desired sol-gel property for periodontal drug delivery. The Herschel-Bulkley model was the best fit model to explain the flow behavior of optimized formulation. Using the HET-CAM method, significantly lower in vitro toxicity was indicated the suitability of developed NEG for intra-pocket delivery.

Abstract
Gels have been considered as a popular mode of delivering medicament for the treatment of sexually transmitted diseases (STDs) (e.g. human immunodeficiency virus, bacterial vaginosis, epididymitis, human papillomavirus infection and condylomata acuminata etc.). The present study discusses the development of novel olive oil based emulsion hydrogels (EHs) using sorbitan monopalmitate as the structuring agent. The developed EHs may be tried as drug delivery vehicle for the treatment of STDs. The formation of EHs was confirmed by fluorescence and confocal microscopy. FTIR studies suggested intermolecular hydrogen bonding amongst the components of the EHs. X-ray diffraction study suggested the amorphous nature of the EHs. The developed EHs have shown non-Newtonian flow behavior. The EHs were found to be biocompatible. The formulations were able to effectively deliver two model antimicrobial drugs (e.g. ciprofloxacin and metronidazole), commonly used in the treatment of the STDs.

Abstract
The present research work focused on the comparative assessment of porous versus nonporous films in order to develop a suitable buccoadhesive device for the delivery of glibenclamide. Both films were prepared by solvent casting technique using the 3(2) full factorial design, developing nine formulations (F1-F9). The films were evaluated for ex vivo mucoadhesive force, ex vivo mucoadhesion time, in vitro drug release (using a modified flow-through drug release apparatus), and ex vivo drug permeation. The mucoadhesive force, mucoadhesion time, swelling index, and tensile strength were observed to be directly proportional to the content of HPMC K4M. The optimized porous film (F4) showed an in vitro drug release of 84.47 ± 0.98%, ex vivo mucoadhesive force of 0.24 ± 0.04 N, and ex vivo mucoadhesion time of 539.11 ± 3.05 min, while the nonporous film (NF4) with the same polymer composition showed a release of 62.66 ± 0.87%, mucoadhesive force of 0.20 ± 0.05 N, and mucoadhesive time of 510 ± 2.00 min. The porous film showed significant differences for drug release and mucoadhesion time (p < 0.05) versus the nonporous film. The mechanism of drug release was observed to follow non-Fickian diffusion (0.1 < n < 0.5) for both porous and nonporous films. Ex vivo permeation studies through chicken buccal mucosa indicated improved drug permeation in porous films versus nonporous films. The present investigation established porous films to be a cost-effective buccoadhesive delivery system of glibenclamide.
