Recent Trends on Transdermal Drug Delivery System

Transdermal drug delivery systems, or TDDS, are a cutting-edge, non-invasive method of systemic medication delivery. Bypassing first-pass metabolism and gastrointestinal breakdown, these systems administer therapeutic chemicals through the skin for a regulated and sustained release. The principles of TDDS, drug permeation mechanisms, formulation elements, transdermal system types, evaluation criteria, and recent developments are all covered in this overview. Compared to more conventional medication delivery methods, the transdermal route offers a number of benefits. These consist of stable medication plasma concentrations, no first-pass hepatic metabolism, good bioavailability, and non-invasive therapy. The stratum corneum, the skin's outermost layer, is the primary barrier to medication molecules penetrating it. It is explained how penetration enhancers and retarders work, as well as how they might be used in clinical settings.
