Abstract:
Transdermal Drug Delivery (TDD) has emerged as a promising alternative to conventional routes of administration, offering controlled drug release, improved bioavailability, and patient compliance. Recent advancements in formulation strategies, penetration enhancers, and novel carrier systems have significantly enhanced the efficacy of transdermal drug delivery. This review comprehensively discusses the fundamental principles, advantages, and limitations of TDD while exploring innovative approaches, including Microneedles (MN), nanoformulations, and iontophoresis, to overcome skin permeability barriers. Furthermore, we highlight recent advancements in polymeric systems and bioresponsive technologies that have revolutionized transdermal therapeutics. Despite notable progress, challenges such as drug stability, skin irritation, and limited drug permeability persist. Addressing these concerns through interdisciplinary research and technological innovations is crucial for further expanding the scope of TDD. This review provides an in-depth analysis of current trends, challenges, and future perspectives to advance transdermal therapeutic systems for enhanced clinical applications.
