摘要：
The present disclosure provides a microneedle array for administering various drugs, a microneedle structure including the microneedle array, a method of fabricating the microneedle array, and a method of fabricating the microneedle structure. The microneedle array of the present disclosure includes a plurality of microneedles, the surfaces of which are coated with a liquid drug and a base for supporting the microneedles. According to the present disclosure, the microneedles are divided into two or more areas, and the surfaces of microneedles disposed in each of the divided areas are coated with different liquid drugs. In this case, the ingredient of a liquid drug coated on microneedles disposed in one of the divided areas is different from the ingredients of liquid drugs coated on microneedles disposed in the remainder of the divided areas.The microneedle structure of the present disclosure includes a plurality of microneedle arrays, some of the surfaces of which are coated with a liquid drug and a body for supporting the microneedle arrays. According to the present disclosure, the microneedle arrays are coupled to the body so that the microneedle arrays are divided into two or more areas, and the microneedle arrays are coated with different liquid drugs. In this case, the ingredient of a liquid drug coated on at least one of the microneedle arrays is different from the ingredients of liquid drugs coated on the remainder of the microneedle arrays.
