Raft Forming System - Gastroretentive drug delivery system

In the recent times several studies and research have been conducted on drug delivery system through mouth in order to overcome several problems like emptying time and gastric retention. Taking medication through mouth is the preferable way compared to others, because of easiness in taking medication and compliance of patients. Limited gastric residence time is the limitation of taking medication orally. In order to increase this gastric retention time, several methods have been proposed. This article focuses on floating drug delivery system to overcome the difficulties associated with design of formulation. Advances and highlights of the floating raft system has been reviewed in this article. Formulation, mechanism, and development of raft forming system is also reviewed in this article.
