PROBLEM TO BE SOLVED: To provide eye drops blended with pranoprofen, having stability over a long period without precipitating the crystal of the pranoprofen even on being preserved under a low temperature environment. SOLUTION: The eye drops are provided by blending dipotassium salt of glycyrrhizinic acid with an aqueous liquid agent of the pranoprofen to increase the solubility of the pranoprofen without precipitating the crystal of the pranoprofen even on preserving under the low temperature environment and further capable of keeping it clear for a long period even in an acidic region.
