AN OVERVIEW ON NOVEL DRUG DELIVERY SYSTEMS

Abstract

The higher demand for enhancing therapeutic efficacy and to reduce adverse effect in the pharmaceutical domain initiate to develop the NDDS in research of pharmacy field. Over past few decades there was greater advancement noted on development of novel drug delivery system. The concept of targeted drug delivery is designed for attempting to compactness drug in the tissues of interest while lowering the relative compactness of the medication in the remaining tissues. Conventional drug delivery system often suffers from limitations of poor bioavailability, rapid clearance and leading to lower the curative success, and increased the side effects. Conventional dosage form also release drug immediately and it causes fluctuation of drug level in blood depending on dosage form. So now new technique novel drug delivery system is applied to overcome the problems by targeted action. Evolution of an existing drug molecule from a conventional form to novel drug delivery can be significantly improve in its performance in term of patient acceptance, safety and efficacy.
