OBJECTIVE Development of liposomal mucoadhesive drug delivery system, which is able to improve the bioavailability of poorly absorbed oral drugs by prolonging their gastric and intestinal residence time, through facilitating the intimate contact of the delivery system with the absorption membrane. MATERIALS AND METHODS Liposomes containing model drug atenolol were prepared by the modified eth...

In this work, the dissolution-absorption studies were conducted on marketed tablets of acyclovir (ACIVIR-200mg) and the mucoadhesive tablets of acyclovir using varying concentration of sodium lauryl sulfate as a permeation enhancer. The purpose of this study was to improve the absorption of acyclovir using sodium lauryl sulfate as permeation enhancer. The everted and perfused intestine model wa...

To develop more potent and convenient mucosal vaccines, we investigated the effect of an in situ-gelling mucoadhesive vaginal vaccine delivery system and a genetic chemokine adjuvant on the local and systemic immune responses. The in situ-gelling mucoadhesive delivery system of hepatitis B surface antigen (HBsAg), composed of poloxamers and polycarbophil, showed the prolonged retention at the v...

A new, novel promising technology for obtaining controlled release and enhancing the bioavailability is a combination of mucoadhesion principle and microencapsulation to result in mucoadhesive microcapsules. Mucoadhesive microcapsules consist of either entirely of a mucoadhesive polymer or having an outer coating enclosing the drug particles. They facilitate an intimate and prolonged contact wi...

BACKGROUND Nanotechnology-based drug delivery systems have been widely used for oral and systemic dosage forms delivery depending on the mucoadhesive interaction, and keratin has been applied for biomedical applications and drug delivery. However, few reports have focused on the keratin-based mucoadhesive drug delivery system and their mechanisms of mucoadhesion. Thus, the mucoadhesion controll...

The primary aim of this work was to investigate the potential of bile salt, sodium taurocholate (NaTC), in improving the bioavailability and anti-tumor efficacy of docetaxel (DCT) upon rectal administration. Poloxamer-based nanomicelles with thermosensitive and mucoadhesive properties were prepared using the cold method. The optimized nanomicellar formulation was evaluated in terms of physicoch...

In present study mucoadhesive buccal tablet of simvastatin was prepared. Solubility of Simvastatin was enhanced by complexing Simvastatin with β-CD in 1:2 molar concentrations. Six different formulations of tablets of Simvastatin containing the polymers in various combinations were prepared by direct compression method and characterized for swelling studies, % matrix erosion, surface pH, mucoad...

The objective of the study was to develop buccal adhesive tablets of Simvastatin using mucoadhesive polymers. Simvastatin has short biological half-life (3hr), high first-pass metabolism and poor oral bioavailability (5%), hence an ideal candidate for buccal delivery system. The tablets were prepared by direct compression technique using xanthan gum, guar gum, chitosan and aloe gum. Aloe gum wa...

Conventional ophthalmic solutions often eliminate rapidly after administration and cannot provide and maintain an adequate concentration of the drug in the precorneal area. To solve these problems, we developed a pH in situ gelling and mucoadhesive ophthalmic drug delivery system containing ketotifen fumarate based on gellan gum. The pasture of ocular drug delivery is one of the fascinating and...

Abstract Background Mucoadhesive polymers are applicable for improving the delivery of drug by prolonging residence time and contact dosage form with mucous membrane. Mucoadhesion may be defined as a process where polymer substance gets adhered either to biological substrate or synthetic natural macromolecule, mucus The can studied determine whether they possess some mucoadhesive properties sev...
