The present study involves preparation and evaluation of gastric-mucoadhesive microparticles with Metformin Hydrochloride as model drug for prolongation of gastric residence time. The microparticles were prepared by the emulsification solvent evaporation technique using polymers of Carbomer 934p (C) and Ethylcellulose (EC). The microparticles were prepared by emulsion solvent evaporation method...

the purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934p as mucoadhesive polymer and ethyl cellulose as carrier ...

Almost 40% of active Pharmaceutical ingredients have low oral bioavailability, high hepatic first-pass metabolism and also less efficient in crossing the blood brain barrier for brain targeting through oral delivery. To overcome this problem the various system such as: nasal spray, gels, emulsions, droplets, suspensions, powders and thermoreversible mucoadhesive gels etc have been studied for n...

The study is related to the formulation and evaluation of mucoadhesive buccal tablets Anastrozole enhance its bioavailability by avoiding 1st pass effect. succeeded in developing containing two layers (mucoadhesive backing layer) a design that permits unidirectional release drug. Tablets were prepared double direct compression method using (carbopol 934) as primary polymer, Sod.alginate, Na CMC...

The purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. Propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934P as mucoadhesive polymer and ethyl cellulose as carrier ...

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...

Oral drug administration has been the predominant route for drug delivery due to the ease of administration, patient convenience and flexibility in formulations. Mucoadhesive tablets of Cephalexin monohydrate were prepared with an objective to increase the bioavailability by minimizing the first pass metabolism and also to reduce the frequency of administration. Carbopol 934p as a primary polym...

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...
