THE CHEMISTRY OF DRUG DELIVERY SYSTEMS (hoá học các hệ dẫn truyền thuốc)

... CLASSIFICATION OF DRUG DELIVERY SYSTEM By the way of delivery:  Targeted drug delivery systems: deliver drug to a desired body location, organ, tissue, specific cells…  Controlled-release drug delivery ... delivery systems: preprogramed drug release. By the route of delivery:  Topical (local) drug delivery systems: drugs are delivered locall...
