A solid dispersion composition characterized by containing 2-benzyl-5-(4-chlorophenyl)-6-[4-(methylthio)phenyl]-2H-pyridazin-3-one, hydroxypropyl methyl cellulose, and polyoxyethylene polyoxypropylene glycol. The solid dispersion composition highly dissolves in water, and a concentration of the 2-benzyl-5-(4-chlorophenyl)-6-[4-(methylthio)phenyl]-2H-pyridazin-3-one which has dissolved is maintained for a certain time. Thus, the compound has improved absorbability in blood. |
