COMPREHENSIVE REVIEW: MICRONEEDLE PATCHES - A PAINLESS REVOLUTION IN TRANSDERMAL DRUG DELIVERY

Microneedles are distributed into several types similar as solid microneedle, carpeted microneedle, concave microneedle, dissolvable microneedle, hydrogel microneedle, swellable microneedle, and pervious microneedle. Microneedles can be made of different accoutrements, and may vary in size and forms. They may also vary in design depending on composition, manufacturing process and area of operation. Silicon, polymers, coating accoutrements, biodegradable accoutrements, several crosslinking ways and biosensing bias are used to fabricate microneedles. The new drug delivery method based on Microneedle (MN) technology provides a painless way to administer medications through the skin while bypassing traditional drug administration methods. The skin microchannels created by MNs enable drug and vaccine and biomolecule delivery with minimal discomfort. The paper examines microneedle technology through its classification systems and production methods and current scientific developments. The paper includes experimental data and results and analysis and future research directions. The creation of microneedle patches will change how drugs are given with improving delivery effectiveness, treatment safety and patient compliance.
