Description
項1、プロスタグランジンD2産生抑制剤を有効成分とする、サルコペニアの予防剤及び/又は治療剤。
本発明における「プロスタグランジンD2産生抑制剤」は、プロスタグランジンD2(本明細書においてはPGD2と記載する場合もある)の合成を阻害する薬剤であれば特に制限されない。
サルコペニアとは、進行性および全身性の骨格筋量および筋力の低下を特徴とする疾患である。European Working Group on Sarcopenia in Older People(EWGSOP)が提唱する分類において、筋肉量の低下の所見のみ見られる場合を「プレ・サルコペニア」、筋肉量の低下の所見、並びに、筋力の低下又は身体能力の低下のいずれか1つの計2つの所見が見られる場合を「サルコペニア」、筋肉量の低下の所見、筋力の低下の所見及び身体能力の低下の所見の3つの所見が見られる場合を「重症サルコペニア」とそれぞれ称する。本明細書においていう「サルコペニア」には、「プレ・サルコペニア」、「サルコペニア」、「重症サルコペニア」のいずれもが含まれる。
本明細書において、「治療」とは、通常、サルコペニアに伴う症状の治癒又は改善、或いは症状の抑制を意味する。「予防」とは、サルコペニアに伴う症状の発現を未然に防ぐことを意味する。
