Abstract

The aim of this work was to develop a mucoadhesive buccal tablet for the buccal delivery of the alendronate via buccal mucosa. Buccal tablets of alendronate are designed to release drug at mucosal site for extended period of time without wash out of drug by saliva. Alendronate sodium is a bisphosphonates which has antiresorptive effect which is implicated in the prophylaxis and treatment of osteoporosis. Sodium alginate, ethyl cellulose and carbopol were selected as mucoadhesive polymers on the basis of their matrix forming properties. The objective of the study is to improve the bioavailability of alendronate buccal tablets. Extensive literature survey was done for the collection of theoretical and technical data. The methodology part includes the explanation of implemented methods in the present study. In present study, an attempt was made to design mucoadhesive buccal tablets containing alendronate, sodium alginate, ethyl cellulose and carbopol using as polymers. The tablets were prepared by direct compression method. The formulations were evaluated for hardness, thickness, friability, weight variation, drug content estimation, surface pH determination, swelling index, in vitro drug release. In vitro bioadhesive strength & in vitro release studies showed that formulation F11 showed optimum bioadhesive & exhibited optimum drug release 97.6% in 7hr. Kinetics results reveals that the F11 formulation follows zero order kinetics as correlation coefficient (r2) values are higher than that of first- order release kinetics.Optimized formula F11 show drug is released by non-Fickian diffusion mechanism. The stability studies of formulation F11 prepared mucoadhesive buccal tablets of alendronate were stable. Overall evaluations of the mucoadhesive of tablets show good mucoadhesive properties.
