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.

The problem of many gastroretentive systems is the mechanistic connection of drug release and gastric retention control. This connection could be successfully separated by formulating hollow tubes via hot-melt extrusion and sealing both tube ends, which led to immediately floating devices.Author: Fabian J.
