Floating Drug Delivery System

Presently, various approaches have been exploited in the prolongation of gastric residence time which includes floating drug delivery system (FDDS), swelling and expanding systems, bio-adhesive systems, modified shape systems and high density systems. Among various methods, floating drug delivery system is considered to be a predominant method. Gastric emptying of dosage forms is an extremely varying process and ability to extend and control the emptying time is a valuable resource for the dosage forms. This FDDS is having the ability to provides a solution for this purpose. The FDDS is a bulk density system lower than the gastric fluid, so that the rest will float on the stomach contents for a prolonged period of time and allowing the drug to release slowly at a desired rate from the system and intensifies the bio-availability of the drug having narrow absorption window. The main intension of writing this review on floating drug delivery system is to study the mechanism of flotation to acheive the gastric retention and to discuss briefly about the background of FDDS, advantages and disadvantages, application of FDDS and factors affecting the gastric retension time.

Recent Advances

Hybrid materials based on Mesoporous Silica Nanoparticles (MSN) have attracted plentiful attention due to the versatility of their chemistry, and the field of Drug Delivery Systems (DDS) is not an exception. MSN present desirable biocompatibility, high surface area values, and a well-studied surface reactivity for tailoring a vast diversity of chemical moieties. Particularly important for DDS applications is the use of external stimuli for drug release. In this context, light is an exceptional alternative due to its high degree of spatiotemporal precision and non-invasive character, and a large number of promising DDS based on photoswitchable properties of azobenzenes have been recently reported. This review covers the recent advances in design of DDS using light as an external stimulus mostly based on literature published within last years with an emphasis on usually overlooked underlying chemistry, photophysical properties, and supramolecular complexation of azobenzenes.
