Microneedles: An Efficient Technique to Increase Transdermal Drug Delivery System

Abstract: Transdermal Drug Delivery Systems (TDDS) have gained attention as a viable substitute for traditional drug administration methods because of their controlled release capabilities and non-invasive design. Microneedles are a new and effective technology that has attracted a lot of attention recently to enhance the capabilities of TDDS further. The study on microneedles and their potential to improve transdermal medication delivery is thoroughly reviewed in this review article. The study initiates by clarifying the difficulties linked to traditional medication delivery techniques and the benefits provided by transdermal channels. The article then explores the development of microneedle technology, outlining the several kinds of microneedles—solid, hollow, and dissolving—as well as their uses. Because of their special capacity to penetrate the skin's protective layer painlessly and their ability to distribute drugs precisely and precisely, microneedles are a highly useful instrument in pharmaceutical research. The materials, geometry, and manufacturing processes that affect the design and creation of microneedles are critically analyzed and presented. The manuscript delves into the latest developments in microneedle technology, encompassing the utilization of biodegradable polymers, smart materials, and sensing components for in-the-- moment monitoring. This analysis concludes by highlighting the noteworthy advancements in the field of microneedles and their potential to transform transdermal drug delivery systems. This thorough knowledge seeks to further the current discussion in pharmaceutical research, encouraging creativity and opening the door for the creation of safer, more effective drug delivery systems.
