Methotrexate (MTX) is now the most popular drug worldwide for the treatment of rheumatoid arthritis. Low-dose, weekly MTX (10 to 25 mg/wk) used as either monotherapy or in combination with other drugs has a superior efficacy profile as defined in placebo-controlled trials and comparable efficacy to other drugs including anti-TNF therapy. At 1 year, one third of patients on MTX have no radiographic progression and even greater effects are seen when combined with targeted biological therapies. MTX is well tolerated; gastrointestinal toxicity is the most common toxicity with rarely bone marrow, lung, or liver toxicity. MTX therapy has been a major advance in the treatment of rheumatoid arthritis and is now the cornerstone of therapy.
甲氨蝶呤(MTX)是目前全球治疗类风湿性关节炎最常用的药物。低剂量、每周一次的MTX(10至25毫克/周),无论是作为单一疗法还是与其他药物联合使用,在安慰剂对照试验中都具有卓越的疗效,并且与包括抗TNF治疗在内的其他药物疗效相当。在1年时,接受MTX治疗的患者中有三分之一没有影像学进展,与靶向生物疗法联合使用时效果更佳。MTX耐受性良好;胃肠道毒性是最常见的毒性,很少出现骨髓、肺部或肝脏毒性。MTX疗法是类风湿性关节炎治疗的一项重大进展,现在是治疗的基石。
