毒理性
在多种条件的多个临床试验中,熊去氧胆酸尚未发现会导致血清酶升高、加重基础肝病或临床上明显的肝损伤。尽管如此,有罕见报道称,在开始使用熊去氧胆酸的晚期肝病和肝硬化患者中出现了临床失代偿的情况,但这类反应的原因尚不清楚。至少在一个实例中,重新开始使用熊去氧胆酸后出现了黄疸复发。因此,熊去氧胆酸对多种形式的肝病有有益效果,并且尚未在没有肝硬化的患者中与临床上明显的急性肝损伤病例有确凿的联系。有一些担忧认为,熊去氧胆酸可能对晚期肝病(Childs B级和C级)患者有害,这类患者可能不应该接受熊去氧胆酸治疗。
n multiple clinical trials in a variety of conditions, ursodiol has not been found to cause increases in serum enzyme elevations, worsening of underlying liver disease or clinically apparent liver injury. Nevertheless, there have been rare reports of clinical decompensation in patients with advanced liver disease and cirrhosis started on ursodiol, but the reason for such reactions is not known. In at least one instance, there was recurrence of jaundice on restarting ursodiol. Thus, ursodiol has beneficial effects on several forms of liver disease and has not been convincingly linked to cases of clinically apparent acute liver injury in patients without cirrhosis. There is some concern that ursodiol may be harmful in patients with advanced liver disease (Childs class B and C) and such patients probably should not receive ursodiol.
