最近一项研究显示,一种治疗类风湿性关节炎的药物对于治疗某种类型的脱发有效果。研究者在66例接受了托法替尼(Xeljanz,tofacitinib citrate)治疗的患者中发现,有50%患者在治疗3个月内长出了新头发。耶鲁大学医学院的皮肤医学助理教授Brett King医师称,托法替尼的作用机制是体制免疫系统攻击发根毛囊。King补充道,对于最常见的脱发类型(男性型态性秃发),这种药物很可能无效果,因为这种类型的脱发并不是自身免疫系统疾病。在这项研究中,King和同事对患者进行了为期3 A recent study showed that a drug that treats rheumatoid arthritis has an effect on the treatment of some type of hair loss. The researchers found that in 66 patients treated with Xeljanz (tofacitinib citrate), 50% found new hair within 3 months of treatment.

King added that the drug is likely to have no effect on the most common type of alopecia (male pattern baldness) because this type of hair loss is not an autoimmune disease. In this study, King and colleagues conducted a 3-year period on patients
