Abstract

The rationale of this research was to prepare a gastroretentive drug delivery system of Ranitidine HCl. Floating Drug delivery system used to target drug release in the stomach or to the upper part of the intestine. Currently, floating tablets are one of the important catagories of drug delivery systems with gastric retentive behavior. Ranitidine hydrochloride is a H2 blocker and absorbed from the upper part of gastrointestinal track and hence there is need to develop a dosage form that release the drug in stomach so that it can be absorbed from upper part of gastrointestinal track leading to improved bioavailability.Four different formulas of ranitidine HCl were prepared by wet granulation using different concentration of hydroxypropyl methylcelluloce K15M, which first formula (FI) without hydroxypropyl methylcelluloce. The formua II, formula III and formua IV used hydroxypropyl methylcelluloce K15M 10%, 20% and 30% respectively. The prepared tablets were evaluated on their physical, floating and drug release characteristics. The dissolution test was performed using 900 ml of 0,1 N hydrochloric acid, at 37 ± 0,5°C and 50 rpm. The result showed that the kinetic release of all the formulas (FII, FIII and FIV) are dominated Higuchi kinetics.
