Targeted Drug Delivery Systems

Target drug delivery system is a different form of drug delivery system where the medicament is selectively transported only to its site of action or absorption and not to the non-target organs or tissues or cells. This system takes the active pharmaceutical ingredient to the pre identified target in therapeutic concentration, while limiting its access to non-target usual cellular linings, thus reducing toxic properties and increasing therapeutic index. Targeting of drugs to different cells and tissues of the body deprived of their becoming a part of systemic circulation is a very novel idea. If a drug can be administered in a form such that it reaches the receptor sites in sufficient concentration without distressing in unimportant tissue cells.
