The transdermal route is employed as an alternate method in many therapeutic applications to get over the important drawbacks of oral medication delivery. Transdermal microneedle arrays have been used for drug administration via the skin for a very long time. Microneedles are devices with a reputation for being highly efficacious and flexible. Microneedles are devices with a reputation for being highly effective and flexible. Intellectual and industrial groups are interested in this technology because of its remarkable properties, which include painless penetration, low cost, excellent medicinal productivity, and relative protection. Microneedles exhibit remarkable properties for a range of biological applications, including the transport of extremely large molecules exhibiting ionic and polar physical-chemical characteristics. In several biological fields, such as immunization delivery, diagnosis, and therapy, microneedles are helpful A new class of instruments with great promise for the biomedical industry is microneedles. In the years to come, transdermal microneedle innovations are expected to become a preferred method of administering medication as they are affordable, painless, and effective.  We describe current breakthroughs in microneedles for therapeutic uses in this study. We investigate the constituent materials and manufacturing technologies that improve the administration of important medicinal compounds through the skin. We also examine the utility of improved microneedles as medication delivery techniques.
