Abstract
In the present investigation, fast dissolving tablets of felodipine were formulated by using super disintegrant croscarmellose sodium and solid dispersion with polyvinyl alcohol (PVA) as a carrier. The tablets were characterized by FTIR study. The formulations were also evaluated for precomressional parameters such as angle of repose, % compressibility and Housness ratio. The post compressional analysis for the parameters such as hardness, friability, in vitro disintegration time, wetting time and in vitro release studies, stability studies were carried out as per ICH guide lines for three months. Tablets prepared by solid dispersion having drug to carrier ratio of 1:4 (A3) yielded the best drug release in terms of dissolution rate. The formulation did not show any change in disintegration time, wetting time and drug content after stability period.
