PROBLEM TO BE SOLVED: To provide medicaments for promoting wound healing and reducing scar formation.SOLUTION: Provided is a pharmaceutical composition comprising pharmaceutically acceptable relaxin in an amount effective for promoting healing of an injury or wound.EFFECT: The composition suppresses formation of TGF-β collagen and collagen that induce proliferation of fibroblast, promotes healing of a wound or cut, promotes wound re-epithelialization, reduces or prevents scarring during wound healing, where LGR7 and LGR receptors are activated by binding of relaxin to trigger nitrogen monoxide (NO) formation.SELECTED DRAWING: None【課題】創傷の治癒を促進し、瘢痕形成を低減するための医薬品の提供。【解決手段】外傷又は創傷の治癒を促進するのに有効な量の薬学的に許容可能なリラキシンを含む医薬組成物。【効果】繊維芽細胞増殖を誘導するＴＧＦ－βコラーゲン及びコラーゲンの生成の抑制し、創傷又は切傷の治癒の促進、創傷の再上皮化を促進、創傷の治癒時の瘢痕化の低減又は防止を行い、ＬＧＲ７及びＬＧＲ受容体が、リラキシンの結合により、活性化し、一酸化窒素（ＮＯ）の生成を引き起す。【選択図】なし
