Transdermal administration of drugs is an another way of administration that can significantly deliver larger molecules in potent quantities that overcome the problem with the oral administration such as poor bioavailability due to first pass metabolism and sometimes responsible for rapid blood level. Drugs that are given by transdermal route may enhance the potency as well as safety of drugs. One such advance has been the development of transdermal patch delivery systems. Transdermal drug technology specialists are continuing to search for new methods that can effectively and painlessly deliver larger molecules in therapeutic quantities to overcome the difficulties associated with the oral route. Transdermal drug delivery system is the system in which the delivery of the active ingredients of the drug occurs by the means of skin. Skin is an effective medium from which absorption of the drug takes place and enters the circulatory system. Various types of transdermal patches are used to incorporate the active ingredients into the circulatory system via skin. The patches have been proved effective because of its large advantages over other controlled drug delivery systems. New transdermal drug delivery system (TDDS) technologies now have been developed that is considered to be helpful in rate controlled delivery of drug that is difficult to administer.
