A Short Review on the Formulation of Transdermal Dermal Drug Delivery System (TDDS)

The transdermal drug delivery systems (TDDS) are drug delivery system that gives rapid, the immediate therapeutic effect of the drug across the patient's skin and its different layers. They are also called as patches. More than 75% of the drugs, now a day's, are taken orally and are not very much effective. To overcome these problems, the transdermal drug delivery system has been evolved. The advantage of transdermal patches is that they deliver the drugs for better systemic effects at a controlled and a predetermined rate. This drug delivery system also endorses the controlled release of drug medicament into the skin of the patients. The chief aim of this drug delivery system is to deliver the drug contents into the systemic circulation through the permeation of skin at a predetermined rate. This article is an overview of different types of transdermal patches, their various method of preparation as well as their various physicochemical evaluation methods. The present study is performed for the motivation of the graduates towards publication and research. Hence, we have encouraged the graduates to prepare an informative article on the present subject.
