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 locally to the target organ/tissue without entering the ... onset of action (comparable to intravenous route) Disadvantages:  lack of reproducibility of the administered dose  variable rate of absorption of drug at different regions THE CHEMISTRY OF...

... and the constraints imposed by the nature of the various routes of administration available for drug delivery. 2 ROUTES OF ADMINISTRATION AND CLASSIFICATION OF DRUG DELIVERY SYSTEMS The ... identified. In A, leakage of the drug occurs as the drug- carrier system moves down the route of administration, whilst in B the drug is lost via the walls of the delivery route to non-target ... targeted drug delivery. Coupled with these activities is the necessary realism of the practical constraints imposed in designing drug delivery systems. These include the necessity of using...
