Abstract

Transdermal Drug Delivery Systems- in the form of patch is treated as a special drug candidate to transdermal administration. The required properties of suitable drugs for patches were high hepatic- first pass effect, and its high lipophilicity, low molecular weight means i.e., having high capacity to cross the skin membrane. A matrix type design is suitable with patch- because of ease manufacturing. So, possible for transdermal patch to release the drug slowly via skin membrane for prolonged period of time and decreases the the frequency of dose administration, which is helpful for the treatment of various diseases. Thus, objective of this study is to provide knowledge on transdermal patches
