Types of Transdermal Drug Delivery Systems: A Literature Report of the Past decade

The work is aimed at giving an overview of transdermal drug delivery systems (TDDS). In TDDS, an effective amount of a drug is applied across the skin at a controlled rate for the systemic effect. TDDS has become increasingly popular. In the last 30 years, it has been proposed as a potential new drug delivery system. These comprise more efficacious treatments and a reduced risk of adverse events; ensure safety; maintain steady-state plasma levels of drugs, while incapacitating the significant hitches of conventional oral dosage forms and parenteral preparations. It is best suited for diseases that require long-term, frequent dosing treatment. This review deals with drugs, polymers, and methods adopted in making TDDS in recent years by referring to reputed journals and textbooks. The authors succeed in gathering the information and the literature on the TDDS. The study concludes that the literature so far will help the researchers with a quick reference on the attempts so far made on TDDS.
