Abstract

The Transdermal drug delivery system (TDDS) also known as patches are the dosage form designed to deliver a therapeutic amount of drug across the patient’s skin. Throughout the last two decades transdermal patch has been proven technology that offers the variety of significant benefit over other dosage form. A skin patch uses a special membrane to control the rate at which liquid drug contained in the reservoir within the patch can pass through the skin and into the bloodstream. Transdermal delivery not only provides controlled, constant administration of the drug, but also allows continuous input of drugs with short biological half-lives, and eliminates pulsed entry into systemic circulation which often causes undesirable side effects.
