Gastroretentive drug delivery is an approach to prolong gastric residence time, thereby targeting site-specific drug release in the upper gastrointestinal tract (GIT) for local or systemic effects. Gastroretentive dosage forms can remain in the gastric region for long periods and hence significantly prolong the

Aug 27, 2011 · CONCLUSION Gastroretentive drug delivery systems are the most preferable systems in order to deliver the drugs which have a narrow absorption window near the gastric region. Now a days a number of drug delivery devices are being developed which aim at releasing the drug at gastric region.

A novel gastroretentive delivery system of RIF was developed for targeting its sustained release in the stomach, a region where RIF has maximum solubility and permeability. This novel delivery system is a revitalized formulation which holds promise to give a new lease of life to an old but potential molecule.Author: Swati Pund, Amita Joshi, Kamala Vasu, Manish Nivsarkar, Chamanlal Shishoo
