PURPOSE:To provide the titled composition composed of an antiallergic agent and/or an antihistaminic agent and an aqueous solution of a carboxyvinyl polymer, having a specific viscosity, free from drooping phenomenon and accordingly effective to administer a definite amount of the drug component surely, and giving no undesirable feeling to the body. CONSTITUTION:The titled composition is composed of (A) an antiallergic agent (e.g. sodium cromoglycate) and/or an antihistaminic agent [e.g. 4-oxo-10-(2,3- dimethylpentanamido)-4H-pyrimido[1,2-C]-quinazoline-3-carboxylic acid sodium salt monohydrate] and (B) an aqueous solution of a carboxyvinyl polymer, and has a viscosity of 60-2,000cps (preferably 300-1,500cps) at 25 deg.C. The con centration of the carboxyvinyl polymer is generally 0.05-0.1%, and when the drug is Na salt, etc., it is 0.1-1%. The viscosity of the composition is preferably adjusted according to the kind of the sprayer, etc.
