Short melting microneedle

摘要

According to the present invention, a microneedle material capable of dissolving in a short-time and being absorbed quickly in order to shorten the application time of the microneedle is provided. A mixture of a water-soluble polymer and one or more saccharides selected from monosaccharides and disaccharides is used as the microneedle material. A systhetic polymer, protein, polysaccharide or a mixture thereof can be preferably used as the water-soluble polymer. Glucose, fructose, sucrose, lactose, trehalose, or a mixture thereof can be preferably used as the saccharides.
