this invention discloses methods for preparing compositions of cyclodextrin polymers for carrying drugs and other active agents . methods are also disclosed for preparing cyclodextrin polymer carriers that release drugs under controlled conditions . the invention also discloses methods for preparing compositions of cyclodextrin polymer carriers that are coupled to biorecognition molecules for targeting the delivery of drugs to their site of action . the advantages of the water soluble cyclodextrin polymer carrier are : drugs can be used that are designed for efficacy without conjugation requirements . it will allow the use of drugs designed solely for efficacy without regard for solubility . unmodified drugs can be delivered as macromolecules and released within the cell . drugs can be targeted by coupling the carrier to biorecognition molecules . synthesis methods are independent of the drug to facilitate multiple drug therapies .
