An Overview on Commonly Used Natural & Semisynthetic Polymers Used in The Floating Drug Delivery System

The objective of the present study is to systematize the recent literature with the core process of floatation in gastric retention. The different polymers used in the development of FDDS. FDDS is a method to deliver the drugs that are active locally with a narrow absorption window in the gastrointestinal tract, unstable in the lower intestinal environment, and possess low solubility with higher pH values. The current study focuses on the various properties of commonly used natural and semisynthetic polymers and their uses in designing gastro-retentive drug delivery system.
