Microsponge and Nanosponge delivery System was originally developed for topical delivery of drugs can also be used for controlled oral delivery of drugs using water soluble and bioerodible polymers. Microsponge delivery system (MDS) can entrap wide range of drugs and then release them onto the skin over a time by difussion mechanism to the skin. It is a unique technology for the controlled release of topical agents and consists of nano or micro porous beads loaded with active agent and also use for oral delivery of drugs using bioerodible polymers.

Improved Stability

The purpose of this study was to develop an oral delivery system for the controlled release of catechin and evaluate the antioxidant potential and stability of catechin loaded PLA/PEG nanoparticles (CATNP). Nanoparticles were synthesized using a double emulsion solvent evaporation method. The fabricated nanoparticles were relatively small with a hydrodynamic diameter of 300 nm and an encapsulation efficiency of 95%. SEM image analysis showed uniform sized and spherically shaped nanoparticles. In vitro release profiles indicated a slow and sustained release of catechin from the nanoparticle. Stability of the nanoparticle in simulated gastric and intestinal fluids is maintained due to the PEG coating on the nanoparticles, which effectively protected catechin against gastrointestinal enzyme activity. Enhanced inhibition action of free radicals and metal chelation potential was noted when catechin was encapsulated in these polymeric nanoparticles. The reports obtained from this study would provide an opportunity for designing an oral delivery system aimed at inhibiting oxidative stress in the human body.

Prolonged Duration

Recently, focus on the development of controlled release drug delivery system has increased, as existing drugs exhibit certain pharmacokinetic limitations. The major goal of designing sustained release formulations is to improve the drug performance by prolonged duration of drug action, decreased frequency of dosing and reduced side effects by using smallest quantity of drug administered by the most suitable route. Osmotic-controlled release oral delivery system (OSMO technology) is the most promising strategy based system for sustained delivery of drug. Drug can be delivered in a controlled manner over a long period of time by the process of osmosis. Osmotic drug delivery system appears to be a promising solution for the limitations of conventional extended release formulations by virtue of their distinguished technological features. The present review describes briefly about various controlled drug delivery systems with special focus on advantages of osmotic-controlled release oral delivery system related to diabetes therapy and improved compliance.
