Formulation and Evaluation of Mouth Dissolving Tablet of Benazepril Hydrochloride

Abstract

Antihypertensive drugs are expected to give quicker action with better bioavailability. In the present study, mouth dissolving tablets of Benazepril Hydrochloride were formulated by using direct compression technique employing combination of a superdisintegrants to achieve rapid disintegration of the tablets in oral cavity Croscarmellose sodium, sodium starch glycolate and crospovidone were used as superdisintegrant to prepare six batches of mouth dissolving tablets out of which tablets prepared from crospovidone showed best results. Drug and physical mixture was characterized by FTIR for compatibility study. Optimization technique was employed to predict the best formulation of all the combinations prepared. Prepared formulations were optimized and evaluated for wetting time, dispersion time and different quality parameters. Optimized formulation was compared with marketed formulation for in vitro drug release and it was found that mouth dissolving tablet shows efficient drug release.
