A transdermal drug delivery system was presented to overcome the difficulties of drug delivery, especiallythe oral route. These drug delivery systems are used in various skin disorders, also in the management of angina pectoris, pain, and smoking. This review discusses the overall introduction of transdermal patches, including types of transdermal patches, the method of preparation of transdermal patches and factors affecting etc. A transdermal patch is a medicated adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin and into the bloodstream. It promotes healing to an injured area of the body. An advantage of a transdermal drug delivery route over other types of delivery system such as oral, topical, i.v., i.m., etc. is that the patch provides a controlled release of the medication into the patient, usually through either a porous membrane covering a reservoir of medication or through body heat melting thin layers of medication embedded in the adhesive. The transdermal drug delivery method has several advantages over other routes of administration. The main disadvantage of transdermal delivery systems stems from the fact that the skin is a very effective barrier, as a result, only medications whose molecules are small can easily penetrate the skin, so it can be delivered by this method. The transdermal drug delivery systems have been designed as an alternative, safest and easiest route for systemic drug delivery.
