Controlled Drug Delivery System for Better Patient Compliance

Controlled drug delivery systems can include the maintenance of drug levels within a desired range and increased patient compliance. The goal of many of the original controlled-release systems was to achieve a delivery profile that would yield a high blood level of the drug over a long period of time. With traditional drug delivery systems the drug level in the blood rises after each administration of the drug and then decreases until the next administration. The key point with traditional drug administration is that the blood level of the agent should remain between a maximum value which may represent a toxic level and a minimum value below which the drug is no longer effective and this can be easily achieved by Controlled drug delivery system.
