Preparation and Evaluation of Gastro Retentive Floating Tablets of Atorvastatin Calcium

This investigation describes the preparation and in vitro evaluation of gastro retentive floating tablets of atorvastatin calcium. Two hydrophilic cellulose derivatives, Methocel K4M and Methocel K15M CR were used in floating tablets as gel forming agents to control drug release. Sodium bicarbonate and citric acid were incorporated as gas generating agents. The tablets prepared by direct compre...

gastro retentive drug delivery systems: a review

gastric emptying is a complex and extremely variable process. this causes the unpredictability of the bioavailability of drug delivery systems. gastro retentive drug delivery systems (grdds)s have received significant interest in the past decades as they can overcome the limitation of conventional oral controlled release drug delivery systems related to fast gastric emptying time. an optimum gr...
