fluctuation in plasma drug concentration at steady state by delivering the drug in a controlled and reproducible manner.2 One novel approach in this area is GRDDSs (gastro retentive drug delivery system). Dosage forms that can be retained in the stomach are called GRDDs. GRDDSs can improve the controlled delivery of

Controlled release drug delivery system (CRDDS) have been most extensively used to improve therapy of certain drugs, but several physiological difficulties faced with CRDDS is the inability to restrain and remain in the gastric region for several hours which limit the bioavailability of drug. Hence drug delivery systems with prolonged gastric residence time (GRT) are an approach to improve ...
