Tranylcypromine, like most monoamine oxidase inhibitors, can cause transient serum aminotransferase elevations in a proportion of patients. These elevations are usually mild, asymptomatic and self-limited and do not require dose modification. Tranylcypromine has also been associated with rare cases of acute, clinically apparent liver injury. The few cases described have resembled those caused by other MAO inhibitors. The time to clinical onset is typically 1 to 4 months and the usual pattern of serum enzyme elevations is hepatocellular (Case 1), although cholestatic injury has also been described. Immunoallergic features (rash, fever, eosinophilia) are uncommon as is autoantibody formation.
Tranylcypromine与其他大多数单胺氧化酶抑制剂一样,可能会在部分患者中引起短暂的血清转氨酶升高。这些升高通常是轻微的、无症状的,并且是自限性的,不需要调整剂量。Tranylcypromine还与罕见的急性、临床上明显的肝损伤病例有关。描述的少数病例与其他MAO抑制剂引起的病例相似。临床发病时间通常为1到4个月,血清酶升高的通常模式是肝细胞性的(案例1),尽管也描述了胆汁淤积性损伤。免疫过敏特征(皮疹、发热、嗜酸性粒细胞增多)不常见,自身抗体的形成也不常见。
