Diabetes mellitus, a widespread and chronic metabolic condition, creates significant challenges for healthcare systems due to complications from inadequate glycemic control, patient non-compliance, and the invasive nature of traditional treatments, including oral medications and insulin injections, which often lead to discomfort, variability in blood glucose levels, and low adherence.
To explore the potential of Transdermal Drug Delivery Systems (TDDS) as a non-invasive and effective alternative for diabetes management, highlighting their advantages, recent technological advancements, and associated challenges.
This review examines the role of TDDS in diabetes treatment, with an emphasis on recent innovations, including microneedles, hydrogels, and sonophoresis. The study also discusses the benefits of TDDS in maintaining stable plasma drug levels, reducing first-pass metabolism, and integrating with continuous glucose monitoring systems.
Emerging TDDS technologies improve drug permeability, enhance bioavailability, and offer sustained drug release, potentially addressing limitations of conventional delivery methods. However, barriers such as skin permeability, high manufacturing costs, and patient variability remain significant challenges.
Multi-drug patches and microneedle-based systems represent innovative approaches that enhance therapeutic efficacy and patient compliance by enabling painless, targeted, and combination drug delivery. With support from nanotechnology and pharmacogenomics, these platforms are evolving toward personalized medicine, offering optimized dosing and reduced side effects.
TDDS presents a promising alternative for diabetes management by improving patient adherence, ensuring controlled drug release, and reducing discomfort associated with injections. While further research is required to overcome existing limitations, advancements in biomaterials and personalized medicine approaches hold the potential to optimize TDDS for widespread clinical application. This research aims to summarize the advancements and address existing challenges for future development.
