非甾体类抗炎药物萘丁美酮是一个前体药物,经肝脏转化为活性代谢产物后,通过抑制前列腺素合成而产生抗炎、解热、镇痛作用。 C 萘丁美酮在大鼠和兔体内无致畸作用,但可产生胚胎毒性作用,如延迟分娩、难产、胎儿生长缓慢等,而且减少胎仔存活率。在孕期前列腺素合成酶抑制剂的使用,增加胎儿动脉导管狭窄,如抑制分娩,孕期延长,损害胎儿肾功能。所以,建议孕妇不要使用任何前列腺素合成酶抑制剂,包括萘丁美酮。因为发现在多种动物模型上,这些药物能阻止胚泡植入,而且能引起自发性流产。动物试验证实,萘丁美酮的活性代谢产物经哺乳大鼠的乳汁分泌。一些认为是较安全的非甾体类抗炎药物中,其中包括布洛芬,但未提及萘丁美酮。 [1]ht p://www.rxlist.com/cgi/generic/nabume_wcp.htm [2]Nielsen GL,Sorensen HT,Larsen H,et al.Risk of adverse birth out come and miscarriage in pregnant users of non-steroidal anti-inflammatory drugs:population based observational study and case-control study.Br Med J 2001;322∶266-70 [3]Levin DL.Ef ects of inhibition of prostaglandin synthesis on fetal devel opment,oxygenation,and the fetal circulation.Semin Perinatol 1980;4∶35-44 [4]Mat DW,Borzel eca JF.Toxic ef ects on the female reproductive system during pregnancy,parturition,and lactation.In Witorsch RJ,editor.
