Controlled drug delivery system

The purpose of this article brings out the fabrication and recent clinical research in osmotic drug delivery system. The technology of osmotic drug delivery system need to be modified for the conventionally control over their release and almost control the safe and effective concentration in the targeted sites. The certain phenomenon of molecule may have low bioavailability hence to be improve by the fabrication osmotic drug delivery system is most promising system for controlled drug delivery system. The pump and technique most is used to developed the research point of view. The number of marketed oral osmotically driven system (OCDDS) has doubled in the last 11 years. The osmotic pressure utilized for osmotic drug delivery system (OCDDS).

Liposome are the concentric bilayer means core of center in which aqueous volume entirely envelope by the phospholipids bilayer used to transfer enzymes, protein and drugs to targets cancer cell or tissue. These are chemical moieties in which action towards target organ. It was first discovered by 1965 and soon was proposed drug delivery system. There are numerous application like anti fungal, anti cancer, anti inflammatory and anesthetic drugs. The magic bullet concept of Paul Ehrlich through very late, offers a logical solution to the age old problem unrelated and unwanted effect of therapeutic agent and optimizing the drug therapy in its true sense. Drugs would be targeted by virtue of groups having affinity for specific cells, tissues or organs. Liposome having also its modifications or upgraded versions likes enzymosomes, hemosomes, virosomes, and erythrosomes. Liposome has emerged as a dynamic mode for targeted drug delivery. Ligands confer specificity on a non specific reagent. Although controlled and sustained drug delivery can be considered as the magic bullet concept. We can look forward to many more clinical products in the future.
