ABSTRACT:
A method for stabilizing an arylcarboxylic acid, which comprises adding a heterocyclic base to the arylcarboxylic acid or a pharmacologically acceptable salt thereof, a stabilizer thereof and an aqueous solution containing a stabilized arylcarboxylic acid. According to the stabilization method of the present invention, arylcarboxylic acid and pharmacologically acceptable salts thereof, particularly pranoprofen, can be stabilized at every temperature range, particularly at lower temperatures, thereby making the production of an aqueous solution to be used as an eye drop, nasal drop, ear drop and the like possible.
