It is intended to provide a combination drug for preventing and/or treating an autoimmune disease. More specifically speaking, a combination drug for preventing and/or treating an autoimmune disease which contains a CaMKII inhibitor and a disease-modifying antirheumatic drug; a medicinal composition, a commercial package, a kit, etc. for the combination; an enhancer for the effect of preventing and/or treating an autoimmune disease of a disease-modifying antirheumatic drug which contains a CaMKII inhibitor as the active ingredient; a method of screening a CaMKII inhibitor appropriately usable in combination, and so on.
3-[(1S)-1-(2-fluorobiphenyl-4-yl)ethyl]-5-[[amino(morpholin-4-yl)methylene]amino]isoxazole is an isoxazole compound useful as a therapeutic agent for an autoimmune disease. The isoxazole compound can be stabilized by using an antioxidant such as a metabisulfite, bisulfite, sulfite or dibutylhydroxytoluene. A pharmaceutical composition for oral administration comprising the isoxazole compound and the antioxidant is an excellent pharmaceutical composition, since the isoxazole compound contained in the composition is stabilized.
