非那西汀(Phenacetinum)及其合剂(如A.P.C)在市场上可以随便购买,因此,有些有慢性疼痛症状(如头痛、关节痛等)的病人,长期自己服用此药。在这些长期大量服用非那西汀的病人中,发现不少人肾脏受到损害,肾功能减退,甚致有的发生尿毒症而死亡。由此看来,在临床实际工作中,对长期应用非那西汀予以预防性限制是必要的。 Phenacetinum and its combination (such as A.P.C) are readily available on the market, so some patients with chronic pain symptoms (headache, joint pain, etc.) take their medicine on a long-term basis. In these long-term use of phenacetin in large numbers of patients, found that many people suffered damage to the kidneys, renal dysfunction, and even some died of uremia. In view of this, in clinical practice, the long-term use of phenacetin prophylactic restrictions is necessary.
