One hundred and eighty-five patients with ulcerative colitis have been studied serially while receiving regular maintenance treatment with sulphasalazine (SASP) in a dose of 0.5 g four times daily. The circulating levels of the drug and its principal metabolites during remission do not influence the liability to relapse. When relapse does occur, the circulating level of sulphapyridine falls and remains depressed until remission occurs. This fall during a relapse is most pronounced when the patient suffers from universal colitis and is least marked in cases of distal colitis.
对185例溃疡性结肠炎患者进行了连续研究,这些患者在接受柳氮磺胺吡啶(SASP)常规维持治疗,剂量为每日4次,每次0.5克。缓解期药物及其主要代谢产物的循环水平不会影响复发倾向。当复发确实发生时,磺胺吡啶的循环水平下降并一直保持在低水平,直到缓解出现。复发期间的这种下降在全结肠炎患者中最为明显,在远端结肠炎患者中最不明显。
