A REVIEW ON MICRO NEEDLE BASED TRANSDERMAL DRUG DELIVERY SYSTEM

Kotha Mounika and Dr. M. Swetha*

Micro needle could be a metric linear unit sized needle its height of 10- 2000μm and also the dimension has 10-50μm, which might penetrate through the cuticle layer to dermal tissue directly while not pain. Microneedles are the wide utilized in the transcutaneous drug delivery system they're painless, efficient, safe, convenient, less invasive, and simple to self-administer with a high drug bioavailability. They're divided in to 4types solid microneedles, coated microneedles, dissolving microneedles, hollow microneedles. Differing kinds of microneedles play totally different roles in numerous analysis fields. Within the recent years, microneedles have oftentimes wont to deliver medication, genes, proteins, RNA & vaccines & have achieved wonderful therapeutic result. In addition, recent biological applications & clinical trials are introduced. Small needles are often improved 3D printing & digital technology contribute to the development of microneedle fabrication technology.
