Abstract

Fabrication of polymeric biodegradable products has gained much attention in solving
environmental pollution, safety and health problems. Furthermore, the biodegradable
polymers have been developed in medicine and drug delivery fields to avoid post-operation
removal of the implants at the end of their functional life. This article introduces some
conventional biodegradable natural and synthetic polymers in medical and drug delivery
applications. In this respect, some factors which may affect degradation and drug delivery
profiles and also, commercial devices based on these polymers are introduced and discussed.
Finally, the physical and mechanical properties of biodegradable polymers are compared
so to be able to choose the most suitable systems in relation to their specific applications.
