RECENT ADVANCES IN TRANSDERMAL PATCHES

Transdermal drug delivery systems (TDDS) have gained significant attention in the field of pharmaceuticals due to their ability to provide a controlled and sustained release of drugs through the skin, thereby bypassing the oral route and its associated challenges.The primary objective of transdermal delivery is to enhance patient compliance by offering a non-invasive and painless mode of drug administration.Various techniques, such as patches, gels, and micro/nanoemulsions, have been developed to facilitate efficient drug permeation through the skin barrier.This review highlights the mechanisms underlying transdermal drug delivery, emphasizing the importance of formulation techniques, skin permeation enhancers, and the selection of appropriate drug candidates.Additionally, the review discusses challenges related to skin permeability, drug stability, and regulatory approval, underscoring the need for continuous research and innovation in formulation technologies.Furthermore, the impact of transdermal drug delivery on specific therapeutic areas, including pain management, hormone replacement therapy, and cardiovascular diseases, is explored.Looking forward, this examines emerging trends such as microneedle-based systems, smart patches, and personalized transdermal therapies, providing a glimpse into the future of drug delivery.As TDDS continue to evolve, they hold the promise of revolutionizing healthcare by improving patient outcomes, ensuring precise drug dosing, and minimizing adverse effects, ultimately leading to enhanced overall quality of life for patients.
