他克莫司是一种免疫抑制剂。它被用于降低器官移植后的排斥风险, 也可以被用作外用药物来治疗T细胞介导免疫产生的疾病,例如异位性皮肤炎牛皮藓. 它还可以用于治疗骨髓移植后的虹彩炎微小病变的恶化、木村氏症白癜风和猫狗的干眼症[2][3]

他克莫司可抑制钙调磷酸酶, 从而影响白细胞介素-2的产生。这种白细胞介素是获得性免疫系统中的一部分,可以促进T细胞的发育和增殖。

它是一种在1987年于一份来自日本的含有的土壤样本中被首次发现的大环内酯[4]

医疗用途

器官移植

他克莫司具有和环孢素相似的免疫抑制性,但效果远强于环孢素. 在一项研究中他克莫司与环孢素相比可以显著降低发生急性排斥反应的概率(30.7%vs46.4%)。[5]在肝移植的第一年中他克莫司的疗效也优于环孢素。[6][7]长期疗效则不及环孢素。他克莫司通常作为器官移植后药物的一种,另外还有 皮质类固醇, 霉酚酸和如 [[en:basiliximab|巴利昔单抗]的白细胞介素-2受体抑制剂]. Dosages are titrated to target blood levels.

溃疡性结肠炎

近几年他克莫司已被用于抑制溃疡性结肠炎。尽管现在它几乎尽在试验中使用,但已经显示出很好的疗效。[8][9]

皮炎

他克莫司可作为软膏来治疗皮肤炎特别是特异性皮炎, . 它以和类固醇相似的方式抑制炎症,效果和中效类固醇相似。他克莫司与类固醇相比具有不会引起萎缩和类固醇的其他副作用[10]

狼疮性肾炎

与其他药物相比他克莫司可以降低狼疮性肾炎严重感染的风险。[11]
