ABSTRACT

Targeted drug delivery system is a potential drug delivery system which delivers the drug to particular organ of interest only. This improves the therapeutic efficacy of the treatment by reducing the side effects of drug which are required in case of anticancer drugs. Erythrocytes have been the most interesting carrier and have found to possess great potential in drug targeting. Resealed erythrocytes are gaining more popularity because of their ability to circulate throughout the body, biocompatibility, zero order release kinetics, reproducibility and ease of preparation. In this review, we have made an attempt to understand the process in detail to prepare resealed erythrocytes, including its mechanism, source and isolation of erythrocytes, methods of drug loading, in vivo and in vitro characterization of resealed erythrocytes, with special emphasis on applications of resealed erythrocytes for cancer treatment. With this review we can conclude that resealed erythrocyte is a promising approach to enhance efficacy of anticancer drugs.
