Abstract:
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.

Claim (Index 16):
The microneedle-coating material according to  claim 13 , wherein\n the water-soluble polysaccharide is at least one kind of compound selected from a group consisting of hydroxypropyl cellulose, hyaluronic acid, chondroitin sulfate, and carboxymethyl cellulose, the monosaccharide is glucose, and the disaccharide is sucrose or trehalose, the surfactant is at least one kind of compound selected from a group consisting of polysorbate 80, polysorbate 20, and polyoxyethylene polyoxypropylene glycol, and the water-soluble polyalcohol is at least one kind of compound selected from a group consisting of glycerin, ethylene glycol, propylene glycol, butylene glycol, and polyethylene glycol with a molecular weight of 500 or less.
