Archana Chaudhary*, Ankaj Kaundal

ABSTRACT

Targeted drug delivery systems deliver the drug to the site of action. Colon Targeted drug delivery is considered as one of the most convenient pathway for the delivery of the drugs or therapeutic agents and used in the treatment of the local diseases. Microencapsulation is the process in which small droplets or particles of liquid or solid material are surrounded or coated by a continuous film of polymeric materials. Microencapsulation is widely used in the pharmaceutical and other sciences to mask taste/ odors, prolong release, impart stability to drug molecules, improve bioavailability, and as multiparticulate dosage forms to produce controlled or targeted drug delivery. Various methods for the preparation of microcapsules are also reviewed. Microencapsulation system offers potential advantages over the conventional drug delivery systems.
