Polymeric drug has good biodegradability and biocompatinbility.It can be used to control the drug release rate

reduce the toxic side effects and drug resistance

and enhance the stability and effective utilization rate.This article reviews recent research progress of polymers with pharmacological activity and polymeric carrier meterials.Polymeric carrier materials are classified in accordance with chemical combining power as polymeric prodrug and polymeric complex.Comparing with the original free drugs

polymeric carriers can optimize free drugs qualities of pharmacokinetics and pharmacodynamics.At last

the research prospects and the problems in this domain are discussed.
