A Panoramic Review on Gastro-Retentive Floating Drug Delivery System

Abstract

Floating drug delivery has been demonstrated to be the most efficacious of the numerous gastroretentive drug delivery mechanism strategies. The concept behind this system has drawn substantial interest in recent decades. Several strategies are currently implemented to prolong the stomach residence durations, such as floating drug delivery systems, swelling and expansion systems, polymer bioadhesive systems, deformation systems, high-density, etc., systems, and various delayed emptying gastric devices. From a formulation and technology standpoint, floating drug delivery equipment is a rather simplistic and straightforward approach. Floating delivery of drug systems is one of the GRDFs used to increase stomach residence duration. The floating medication delivery device can persist in the gastrointestinal region for several hours due to its floating action on the stomach contents, extensively enhancing the gastrointestinal residence period of drugs. The main thrust of this review is on the design, factors, characterization, applications, evaluation criteria, and prospective future gastro-retentive floating medication delivery techniques.
