Abstract :
Transdermal microneedle array technology has emerged as a promising innovation in drug delivery, addressing the limitations of conventional transdermal systems by enhancing skin permeability while maintaining a minimally invasive approach. Microneedles, which are tiny needles ranging from 50 to 900 micrometers in length, create microchannels in the skin’s stratum corneum, the primary barrier to drug penetration. This allows for the effective delivery of various therapeutic agents, including large molecules and biologics, that would otherwise be unable to permeate the skin. There are several types of microneedles, including solid, coated, dissolving, and hollow microneedles, each with distinct mechanisms for drug delivery. Solid microneedles create pathways for subsequent drug application, while coated and dissolving microneedles deliver drugs directly through dissolution or degradation within the skin. Hollow microneedles facilitate the direct injection of liquid formulations into the dermis. These designs enable precise dosing, targeted delivery, and controlled release, making them suitable for a wide range of applications, including vaccine administration, diabetes management, cancer therapy, and cosmetic treatments. Microneedle arrays offer significant advantages such as improved patient compliance due to their painlessness, reduced risk of infection, and the potential for self-administration. However, challenges such as manufacturing complexity, variability in skin penetration, and drug stability remain. Ongoing research and development are focused on overcoming these obstacles, with future directions exploring the integration of microneedles with wearable devices and smart drug delivery systems. Transdermal microneedle technology represents a significant advancement in drug delivery, offering a versatile and patient-friendly alternative to traditional methods.
