ABSTRACT

The aim of extended release formulation is to increase the bioavailability, as it is important in the optimization of the drug development. BCS is a valuable tool in pharmaceutical science. Formulation scientist can optimize the drug development by applying the prediction of solubility & permeability which have influence on the dissolution profile of a drug product & ultimately on Bioavailability & Bioequivalence. In the present review the role of Biopharmaceutics classification system (BCS) is given in the extended release drug delivery system of BCS class I drugs. Mathematical models enable the quantitative analysis of drug release kinetics which reduces time during drug formulation & serves as important tool in product development & optimization.

Keywords: Biopharmaceutics classification system, Bioavailability, Bioequivelence, solubility, Permeability, extended release.
