Review on microspheres as a drug delivery carrier

Abbaraju Krishna Sailaja, Anusha K


A well designed controlled drug delivery system can overcome some of the problems of conventional therapy and enhance the therapeutic efficacy of a given drug .To obtain maximum therapeutic efficacy, it becomes necessary to deliver the agent to the target tissue in the optimal amount in the right period of time there by causing little toxicity and minimal side effects. There are various approaches in delivering a therapeutic substance to the target site in a sustained controlled release fashion. One such approach is using microspheres as carriers for drugs. In this article importance of microsphere as a novel drug delivery carrier to attain site specific drug delivery was discussed.
