This review highlights recent advancements in microneedle-based transdermal drug delivery systems, focusing on their potential for long-acting applications in wearable devices. It categorizes microneedles by delivery mechanism and emphasizes the use of biodegradable synthetic and natural polymers, such as PLA, PLGA, PCL, silk fibroin, and chitosan, for sustained drug release. The review also discusses the integration of advanced drug carriers like liposomes and polymeric nanoparticles to enhance drug-loading capacity and prolong release duration. Key challenges for clinical translation include ensuring manufacturing consistency, maintaining sterility, and validating long-term in vivo efficacy and safety.
