Floating Drug Delivery System: As A Novel Approach for Drug Delivery
Abstract
The retention period of the drug and dosage form in the stomach is very challenging for the treatment of gastrointestinal disease. To solve this problem and improve the efficacy and bioavailability of the drug, most researchers develop a novel carrier system that is called a Floating drug delivery system (FDDS). The goal of this review on floating drug delivery systems (FDDS) is to synthesise contemporary material with a particular concentration on the main mechanism of flotation for stomach retention. The physiology of the stomach (including gastric pH and movement) has been shown a major effect on gastrointestinal holding period and drug delivery behaviour in both intra- and inter-subject variability. The most recent advancements in the Floating drug delivery system (FDDS) are thoroughly reviewed, including the physiological and formulation factors that influence stomach retention, design methods for single-unit and multiple-unit floating systems, and their categorization and formulation characteristics. A synopsis of the research that has been done to determine the effectiveness and utility of floating systems, as well as uses for such systems, is also included in this review. This study covers the most recent Floating drug delivery system (FDDS) technology advances, including patented delivery techniques and commercial devices, along with their benefits and potential applications for oral controlled drug administration in the future.
Keywords: Floating drug delivery system, Gastric-emptying time, Inter-digestive myoelectric cycle (IDMC), Polymers, Bioavailability, Membrane permeability.
