prednisone
プレドニン
解説 Definition
prednisone は、炎症や免疫反応を抑えるために使われるステロイド薬の一種を指す名詞です。日本語の「プレドニン」は商品名として使われることがありますが、英語の prednisone は成分名として広く使われます。
Prednisone is a synthetic corticosteroid medicine used to reduce inflammation and suppress immune-system activity in a range of medical conditions. It is the generic name of an active drug ingredient and should be distinguished from brand names and from the related medicine prednisolone.
覚え方のコツ Memory Tip
prednisone は商品名ではなく薬の有効成分を表す一般名で、炎症や免疫反応を抑える corticosteroid の一種。prescribe prednisone、take prednisone のような医療場面で覚える。似た prednisolone は別成分なので、語尾の -sone と -solone を混同しない。
Remember prednisone as the generic drug name, not as the name of the whole steroid class or a particular brand. Place it in typical medical combinations: a doctor prescribes prednisone, a patient takes prednisone, and a pharmacist explains a prednisone dose. Its main role is to reduce inflammation or suppress an excessive immune response. The most useful distinction is from prednisolone: the names look very similar, and the medicines are closely related, but they are not identical ingredients. Focus on the ending -sone in prednisone versus -solone in prednisolone, and always preserve the exact name when reading a prescription or label.

prednisone の類義語・関連語
prednisone の語源・成り立ち Etymology
20世紀の薬学造語で、steroid 骨格を示す pregnane、二重結合2本を表す diene、cortisone を縮めて作られました。化学名の部品をつないだ語なので「コルチゾン系の合成ステロイド」と分かりやすく、関連語に prednisolone, cortisone があります。
Prednisone is a twentieth-century pharmaceutical coinage created within the naming system for synthetic corticosteroids. Its form reflects chemical naming elements associated with the pregnane steroid framework, diene structure, and cortisone-related compounds. It was coined as a technical drug name rather than inherited as an ordinary vocabulary word. The similar form prednisolone names a closely related compound, with the additional element reflecting a chemical difference between the two medicines.
