Many methods were used to devise peptide and protein drugs delivery system (DDS). Because of their relatively large size, they have low transdermal bioavailabilities. In systemic delivery of proteins, biodegradable material as parenteral depot formulation occupy an important place because of several aspects like protection of sensitive proteins from degradation, prolonged or modified release, pulsatile release patterns. The main objective in developing controlled release protein injectables is avoidance of regular invasive doses which in turn provide patient compliance, comfort as well as control over blood levels. This review article presents the outstanding contributions in field of microencapsulation as protein delivery systems and different approaches of protein delivery are described. Then discusses how these advances may be applied to resolve the challenges face the development of microcapsule for the controllable delivery of protein drugs.
