摘要
To provide a composition of a coating liquid for microneedle which is optimal for coating a microneedle with a medicinal ingredient.;The coating liquid for microneedle of the present invention is an aqueous solution containing, as essential components of a base, a water-soluble polysaccharide, a monosaccharide and/or a disaccharide and a surfactant, characterized in that a ratio of the water-soluble polysaccharide to the base is 2 to 60 mass %, and the hardness after being dried is 10 N or more. The coating liquid for microneedle may further contain a water-soluble polyalcohol, and preferably a monosaccharide and/or a disaccharide is 30 to 95 mass %, a surfactant is 0.05 to 5 mass %, and a water-soluble polyalcohol is 10 mass % or less in the base. As the water-soluble polysaccharide, hydroxypropyl cellulose, hyaluronic acid, or carboxymethyl cellulose is preferable.
