also: メディシン
noun
Loanword from English, used in contexts such as music, sports, or brand names rather than as the standard Japanese word for medical treatment (which is 薬 or 医学).
彼の新しいアルバムは「メディスン」というタイトルだ。
His new album is titled 'Medicine'.
このバンドの曲はメディスン・ロックと呼ばれることがある。
This band's music is sometimes called medicine rock.
Borrowed from English 'medicine'. The exact derivation is uncertain; it may have entered Japanese through music, brand names, or specific cultural references rather than as a general medical term.
