Recently, the most widely used conventional dosage form such as tablets capsules, and injections but due to some cases we are preferable to choose the transdermal drug delivery system (TDDS) because conventional oral dosage forms undergo first-pass metabolism. Delivery of drugs through the skin has been always a challenging area for research due to barrier properties exhibited by the outermost layer the of skin stratum corneum. Nowadays different types of skin penetration enhancement techniques are used for increasing the penetration. These types of techniques also increase bioavailability. The patient has more preferable to choose this type of drug delivery system because it has more advantages than the conventional dosage form. This article discusses the anatomy and physiology of skin and its drug penetration capacity. Polymers used in transdermal drug delivery of different types of TDDS and marketed.
