ABSTRACT Objective: Transmucosal buccal drug delivery could be an alternative for oral administration for systemic delivery of Verapamil Hydrochloride (VH), as it has low bioavailability 20 - 35 % due to its extensive rst pass metabo- lism and variable absorption at GIT. Method: Buccal patches of VH were prepared by solvent casting method using bioadhesive polymers HPMC K4M, Carbopol 934P, Chitosan acetate and Okra mucilage isolated from Hibiscus esculantus fruits, in various combinations as...

ABSTRACT The development of an appropriate dosage form for pediatric patients needs to take into account several aspects, since adult drug biodistribution differs from that of pediatrics. In recent years, buccal administration has become an attractive route, having different dosage forms under development including tablets, lozenges, films, and solutions among others. Furthermore, the buccal epithelium can allow quick access to systemic circulation, which could be used for a rapid onset of...

Purpose: To prepare and characterize buccal transmucosal delivery system of enalapril maleate for overcoming its low bioavailability, and hence provide improved therapeutic efficacy and patient compliance. Methods: Transmucosal drug delivery systems of enalapril maleate were formulated as buccal films by solvent casting technique using polyvinylpyrrolidone K90, hydroxypropyl methylcellulose, sodium carboxymethylcellulose (high viscosity). The films were evaluated for film weight, thickness,...

Based on the advantages of adhesion preparations and the application status of microspheres (MSs) in mucous delivery, this paper primarily reviews the bioadhesive MSs via transmucosal administration routes, including the mucosa in alimentary tract and other lumens. Particularly, the detailed researches about of celladhesive MSs and some new-style bioadhesive MSs are mentioned. Furthermore, this review attempts to reveal the advances of bioadhesive MSs as cell-selective bioadhesion systems and...
