Advancements in Transdermal Drug Delivery System

Transdermal drug delivery system has emerged apromising alternative to traditional oral and injectable methods for delivering therapeutics through the skin. This system facilitates controlled release of drugs over extended periods. Today about 74% of drugs are taken orally and are found not to be as effectual as long. To improve such character’s transdermal drug delivery system was become apparent. Advances in TDDS have been significantly made by developments in permeation enhancers, novel drug formulation and the use of micro needles nanoparticles to increase penetration. The gloopy of the TDDS is critical to the safety, efficacy and quality of a drug. In this review, we describe the different types of available TDDS methods, along with a critical discussion of the specific advantages and disadvantages, characterization methods, and potential of each method¹.
