Abstract
In order to develop a desirable in vitro release which correlates well with in vivo bioavailability, hollow type suppository containing Propranolol HCl(PPH) powder in the cavity and conventional type suppository with dispersed PPH in the base were prepared. Polyvinyl alcohol (PVA) hydrogel as a base and PPH as a model drug were used for the preparation of suppository. The rates of drug release from the suppositories were studied by Paddle method, Muranish method, Dialysis tubing method and Rotating dialysis cell method. The release profiles from suppositories using the four different release tests were compared. After a rectal administration in rat, the mean
