The anion exchange resin cholestyramine binds methotrexate (MTX) effectively in vitro. The binding capacity exceeds that of activated charcoal by a factor of 5.4. On two patients undergoing high-dose MTX therapy it is also shown that cholestyramine binds MTX in vivo. This leads to an enhanced non-renal excretion of MTX. Therefore, cholestyramine may be of clinical value in patients who develop renal function impairment whilst undergoing MTX therapy.
阴离子交换树脂消胆胺在体外能有效结合甲氨蝶呤(MTX)。其结合能力比活性炭高出5.4倍。在两名接受大剂量MTX治疗的患者中也表明,消胆胺在体内能结合MTX。这导致MTX的非肾排泄增加。因此,消胆胺对于在MTX治疗期间出现肾功能损害的患者可能具有临床价值。
