Since loxoprofen or an alkali addition salt thereof contains a specific amount of malic acid as a pH adjusting agent, loxoprofen or an alkali addition salt thereof is uniformly dissolved and dispersed in an adhesive base, and loxoprofen or an alkali addition salt thereof is obtained. An object of the present invention is to provide an anti-inflammatory analgesic that prevents crystallization of the composition and is excellent in stability over time in an adhesive. SOLUTION: 0.5 to 1.5% by mass of malic acid is contained in 100% by mass of an adhesive base containing loxoprofen or an alkali addition salt thereof. [Selection] Figure 1 |
