Floating Drug Delivery System: An Outlook

Floating Drug Delivery System: An Outlook


  • Himal Barakoti




Floating drug delivery approach uses low-density systems that have sufficient buoyancy to flow over the
gastric contents and remains buoyant in the stomach without affecting the stomachic emptying rate for a
chronic period of time. This result is increased gastric retention time and better control of the fluctuations
in plasma drug concentration with a low risk of toxicity. Drugs, which are locally active in the stomach,
drugs having narrow absorption window and unstable in the intestine, and colonic environment, are the
potential drug candidates. The approach not only improves drug absorption but also minimizes the mucosal
irritation of drugs. As the approach requires a high fluid level in the stomach to float and work efficiently,
it makes the approach limited up to some extent. Many buoyant systems have been developed based on
granules, powders, capsules, tablets, laminated films, and hollow microspheres and few formulations have
been commercialized in the market at the present time. This review gives an overview of the approach of
floating drug delivery at present with sequential demystification thus enabling a greater understanding of
their role in medicine and drug delivery
