The controlled release of drugs in slow and sustained manner is one of the major challenges in drug delivery system. Targeting of drug to the particular site is an important aspect of drug delivery system. This delivery system also used for lipophilic drug which are soluble in intestine. Microparticles were initially developed as carrier for vaccines & anticancer drugs. They have now been used to increase the efficiency of drug delivery system & improve release profile & for drug targeting. These delivery systems offer numerous advantages compared to conventional dosage forms, which include improved efficacy, reduced toxicity, improved patient compliance and convenience Microparticles have been proven to be useful in this manner for the delivery of various active pharmaceutical ingredients. The current aim of this review is to study various aspects of the microparticulate drug delivery system including method of formulation, evaluation & characterization.
