Phenaridine (2,5-Dimethylfentanyl) is an opioid analgesic that is an analogue of fentanyl. It was developed in 1972,〔Riley NT, Hale DB, Wilson MV. 4-Anilidopiperidine Analgesics I: Synthesis and Analgesic Activity of Certain Ring-Methylated 1-Substituted 4-Propananilidopiperidines. ''J. Pharm. Sci'' 62(6): 983 (1973)〕 and is used for surgical anasthesia.〔Osipova NA, Petrova VV, Novikov GA, Dolgopolova TV, Zhukova OI, Mel'nikova ZL, Smolina TA. The new Soviet narcotic analgesic phenaridine as a component of general anesthesia during cancer surgery. (Russian).

The evaluation of the analgesic action of phenaridine when combined with agents used in anesthesiological practice. (Russian). ''Farmakologiia i Toksikologiia''. 1991 May-Jun;54(3):17-20.〕 Phenaridine has similar effects to fentanyl. It is slightly less potent than fentanyl in rats.〔 Side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening. Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear. ==See also== * 3-Methylfentanyl * 4-Fluorofentanyl * α-Methylfentanyl * Acetylfentanyl * Furanylfentanyl * List of Fentanyl analogues 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phenaridine」の詳細全文を読む スポンサード リンク
