Erythrocyte as Drug Carrier

The use of erythrocyte as drug carrier has been reviewed, Carrier erythrocytes have proven to offer many advantages for delivery of therapeutic agents, especially in the treatment of inherited enzyme deficiency and cancer. Carrier erythrocytes are biodegradable and nonimmunogenic. Encapsulated drugs may be protected from premature degradation, inactivation and excretion. Carrier erythrocytes may be used as a slow-release system. Targeting of encapsulated drugs directly to a site of action is another possibility. Methods for encapsulating drugs into erythrocytes, the fate of carrier erythrocytes in vivo, the strategies of targeting carrier erythrocytes to special organs and in vivo applications of erythrocytes have been discussed. The encapsulation of drugs in erythrocytes has shown attractive possibilites in future use.
