Drug targeting to specific organs and tissues has become one of the critical endeavors of the new century. The search for new drug delivery approaches and new modes of action represent one of the frontier areas which involves a multidisciplinary scientific approach to provide major advances in improving therapeutic index and bioavailability at site specific-delivery. The hard target tissues such as blood-brain barrier permeation, pulmonary, rectal, limitation can now be overcome allowing the use of therapies otherwise excluded by conventional dosage forms. In the treatment of health related dysfunctions, it is desirable that the drug reaches its site of action at a particular concentration and that this therapeutic dose range remains constant over a sufficiently long period of time to alter the process. So the knowledge of these drug delivery systems is very essential and important. Keeping this in mind the review is designed to cover most of the aspects of various drug delivery systems....
