Drug delivery systems alternative

A pharmacotectonics concept was illustrated by researchers, in which drug-delivery systems were arranged spatially in tissues to shape concentration fields for potent agents. NGF-releasing implants placed within 1-2 mm of the treatment site enhanced the biological function of cellular targets, whereas identical implants placed mm from the target site of treatment produced no beneficial effect (Mahoney and Saltzman, 1999). Because of some limitations with controlled delivery systems, alternatives such as encapsulation of cells that secrete these factors are discussed in the next section. [Pg.66]

A number of drugs reach a delicate state of patent by 2005. Therefore, an alternative is required for new drug development the formulation of drugs into separate delivery mechanisms, often known as drug delivery systems. Clearance for these innovative formulations as abbreviated new drug applications (ANDA) is easier, compared with a new drug entity that requires approval of the United States Food and Drug Administration (USFDA). [Pg.269]
