Estimating the term…
The present invention relates to a drug-coated microneedle and a method of manufacturing the same, and more particularly to a drug-coated microneedle that delivers a drug by physically piercing the stratum corneum of the skin and a method of manufacturing the same. The drug-coated microneedle is represented by Chemical Formula 1 below, and is capable of releasing a drug through a redox reaction after penetration into the skin. The drug-coated microneedle according to the present invention is capable of effectively delivering a drug having excellent functionality but low skin permeability, and is thus useful as a material for functional cosmetics for whitening, wrinkle reduction, inflammation reduction and the like. [Chemical Formula 1] MN-S—S-D. In Chemical Formula 1, MN is a silica-(SiO2)-containing microneedle, S—S is a disulfide bond, and D is a drug.
A method of manufacturing a drug-coated microneedle, which is represented by Chemical Formula 1 below and in which a drug is released through a redox reaction after penetration into a skin, comprising:
A drug-coated microneedle, which is represented by Chemical Formula 1 below and in which a drug is released through a redox reaction after penetration into a skin:
