A Review on Floating Multi-particulate Drug Delivery System

Abstract

The objective of writing this review on Floating Drug Delivery Systems (FDDS) was to accumulate new work with a special focus on the primary floatation mechanism for gastric retention. Drug delivery systems are those that instantly float on contact with gastric fluids and present promising approaches to improve the bioavailability of drugs with absorption windows in the stomach or upper small intestine, imbalanced in the intestinal or colonic environment, and exhibit low solubility at high pH standards. It is a novel drug delivery system that takes full advantage of effectiveness and compliance. Physical problems such as short gastric residence time and unpredictable gastric emptying time were overcome with the use of floating dosage forms that provide the possibility of local and systemic effects. The floating drug delivery system allows prolonged and continuous entry of the drug into the upper part of the gastric retention pathway and increases the bioavailability of the medication characterized by a narrow absorption window. This review provides detailed information on the pharmaceutical basis of its Introduction, Advantages, Disadvantages, Factors Affecting Gastric Emptying, and Criteria for Suitable Drug Products for Floating Gastric-Retention, Classification of Floating Multiparticulate Drug Delivery System, and Characterization of Floating Multiparticulate Drug Delivery System. These systems are beneficial for various difficulties encountered during the development of a pharmaceutical dosage form and the future potential of FDDS. This review article has attempted to announce to readers about the floating drug delivery system.
