| 摘要 |
The main purpose of the invention is to provide a new specific crystal of 2-methyl-c-5-[4-[5-methyl-2-(4-methylphenyl)-1,3-oxazol-4-yl]butyl]-1,3-dioxane-r-2-carboxylic acid. The invention includes, for example, a crystal of 2-methyl-c-5-[4-[5-methyl-2-(4-methylphenyl)-1,3-oxazol-4-yl]butyl]-1,3-dioxane-r-2-carboxylic acid, which has peaks at the angles of diffraction of at least 12.4°, 17.1°, and 20.8° in a powder X-ray diffraction spectrum, and a preventive or therapeutic agent comprising the crystal as an active ingredient for use in coronary artery diseases, cerebral infarction, hyperlipemia, arteriosclerosis, diabetes mellitus, hypertension, or obesity.
