A Comprehensive Note on Gastro-Retentive Dosage Forms

Controlled release drug delivery system has achieved greater importance in the field of pharmaceutical sciences to provide therapeutic advantages over the conventional drug delivery system. Nowadays, the gastrointestinal controlled drug delivery systemis more prominent than the controlled release system because these can govern the release rate of therapeutically active drug for a sustained period. A Gastro retentive dosage form improves the therapy by prolonging the gastric residence time of the drugs. Prolonged gastric retention improvesbioavailability, reduces drug waste and improves solubility for drugs that are less soluble in a high pH environment. In this review, we have discussed various systems associated with gastro retentive drug delivery with their effective mode of action. Also, the approaches and factors to increase the gastric retention time have also been discussed. This drug delivery system has potential to overcome the limitations of the conventional system. The present study is performed for the motivation of the graduates towards publication and research. Hence, we have encouraged the graduates to prepare an informative article on the present subject.
