ABSTRACT OF THE DISCLOSURE An aqueous agent comprising at least one arginine amide selected from the group consisting of (2R,4R)-4-methyl-1-[N2- ((RS)-3-methyl-1,2,3,4-tetrahydro-8-quinolinesulfonyl)-L- arginyl]-2-piperidinecarboxylic acid, monohydrate thereof and pharmacologically acceptable salts thereof, and at least one compound selected from the group consisting of cyclodextrin and caffeine; a method for improving the solubility of arginine amide in water, comprising adding at least one compound selected from the group consisting of cyclodextrin and caffeine; and a method for stabilizing arginine amide in water, comprising adding caffeine. According to the present invention, the solubility of arginine amide in water can be enhanced to, for example, a concentration permitting inhibition of fibrin formation at the time of entoptic operation. In addition, the stability of arginine amide in water can be enhanced with less irritation of the eye.
