ABSTRACT

Now day’s Recent advances in the understanding of pharmacokinetic & pharmacodynamic behaviour of drug have offer a more rational approach to the development of optimal drug delivery system. Now it's appreciable that future success in Drug delivery research will largely be result of multidisplinary efforts. If any therapeutic agent that can be the more efficacious and safe using and improved drug delivery system represent both lucrative marketing opportunities for pharmaceutical company and advancement in the treatment of diseases of mindkind. An ideally design drug delivery system delivers a specified amount of drug to target particular site at an appropriate time and rate as dictated or desired by the etiological and physiological needs of the body. Conventional Pharmaceutical Dosage forms are incapable of controlling the rate of drug delivery to target site. As a result the distribution of drug in non- target tissue and body fluids necessitate therapeutic doses that could far exceed the amount required in target cells, the higher doses often lead to serious adverse during treatment thus, the novel drug delivery systems (NDDS) are carriers which maintain the drug concentration in therapeutic range for longer period of time and also, in addition, may deliver the content to the site of action if so desired as per requirements.

Keywords: drug delivery systems, therapeutic agent, diseases, target site, body fluids, non- targeting tissues, drug etc.
