Nanosponge and Micro Sponges: a Novel Drug Delivery System

Nanosponge and Microsponge 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. It holds a promising future in various pharmaceutical applications in the coming years like enhanced product performance and elegancy, extended release, reduced irritation, improved thermal, physical, and chemical stability of product. A Nanosponge and Microsponge delivery system can entrap wide range of drugs and then release them onto the skin over a time and also in response to other stimuli including rubbing, moisture, pH, friction, or ambient skin temperature. 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, especially for colon specific delivery and controlled release drug delivery system.
