Innovation in Menstrual Pain Management: A Systematic Review of 3D-Printed Personalized Patches for Dysmenorrhea

This article discusses the potential of 3D printed, patient-tailored transdermal patches in the treatment of dysmenorrhea. Dysmenorrhea occurs in 45% - 95% of individuals of reproductive age and is often inadequately recognized and sub optimally treated. The article consolidates mechanisms of the disease, clinical presentation and available therapeutic options, highlighting their shortfalls. It is followed by a section presenting 3D printing applications in pharmaceutical sciences and focuses on the part played by these in the field of personalized drug delivery. Different Additive Manufacturing strategies (filament deposition, resin injection, powder sintering machine and powder fusion process) are compared in terms of opportunities and threats: Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS) and Direct Energy Deposition (DED). Formulation, material selection and analytical aspect for 3D printed patch are discussed. Advantages of these patches are a personalized fitting, possibility for complex geometries, and precise control over dose and release-kinetics. Applications go beyond menstrual pain to vaccine delivery and personalized medicine. The review also contrasts 3D-printed patches with therapeutic options such as heat therapy, herbal agents and systemic medications along with the limitations that accompany them. Obstacles to adoption —costly equipment and materials, regulatory uncertainty, challenges scaling production — are recognized. Future prospects are with the use of biosensors, AI-driven personalization and 4D printing for responsive release. The conclusion emphasizes the disruptive potential of 3D-printed patches in clinical applications and advocates for additional research, development and regulations to bridge this platform technology from bench-to-bedside for better patient outcomes.
