如題 Ketorolac的結構分類? 維基百科寫說 Although its name does not suggest similarity with propionic acid derivatives (e.g. ketoprofen, flurbiprofen, naproxen, ibuprofen, carprofen etc.), ketorolac is an isostere of ketoprofen. More precisely, it is a dihydropyrrolizine carboxylic acid derivative structurally related to indomethacin. 所以Ketolor是和ketoprofen, flurbiprofen, naproxen, ibuprofen 同類屬propionic acid類衍生物, 還是和Diclofenac,Etodolac,Indomethacin,Sulindac屬Acetic acids類衍生物 (因為有ac結尾) ? 謝謝
