Drug targeting in cancer chemotherapy: a clinical perspective

Abstract

Drug targeting is a phenomenon which maneuvers the distribution of drug in the body in such a manner that the major fraction of the drug interacts exclusively with the target tissue at a cellular or subcellular level. Numerous strategies have been developed to accomplish this goal; some of them have been tried clinically for improving cancer chemotherapy. This review updates the current status of research in the area of targeted drug delivery, with particular emphasis on its application in the clinical management of carcinomas.
