Disclosed herein are a novel
dicarboxylic acid salt of N,N-dimethylimidodicarbonimidic diamide, a preparation method thereof and a pharmaceutical composition comprising the same. More specifically, disclosed herein are a novel
dicarboxylic acid salt of N,N-dimethylimidodicarbonimidic diamide, a crystalline acid addition salt prepared by allowing N,N-dimethylimidodicarbonimidic diamide to react with a specific
dicarboxylic acid, which has improved physical and chemical properties including
solubility, stability, non-hygroscopicity and anti-
adhesive properties, and
low toxicity, and thus is very effective in the prevention and treatment of not only diabetes and its complications in patients with so-called metabolic syndromes, in which diabetes,
obesity,
hyperlipidemia,
fatty liver,
coronary artery disease,
osteoporosis,
polycystic ovary syndromes, etc. appear in combination, but also p53
gene-deficient cancers, muscular pain,
muscle cytotoxicity and rhabdomyolysis, as well as a preparation method thereof and a pharmaceutical composition comprising the same.
