Next-Generation Transdermal Drug Delivery via Patch Technology

Transdermal drug delivery systems (TDDS) have emerged as a promising alternative to conventional routes of drug administration, offering numerous advantages such as bypassing the gastrointestinal tract, avoiding first-pass metabolism, and providing controlled and sustained drug release.Among these systems, transdermal patches represent a non-invasive and patient-friendly approach that enhances therapeutic efficacy and patient compliance.This review highlights the advancements in next-generation transdermal patch technologies, including the incorporation of novel materials, penetration enhancers, microneedles, iontophoresis, and nanocarrier-based systems to overcome the limitations of traditional patches.Emphasis is placed on the design considerations, mechanism of drug permeation, recent FDA-approved products, and potential future directions.As research progresses, next-generation transdermal patches are poised to revolutionize drug delivery, especially for chronic conditions requiring long-term therapy.
