毒理性
关于司替戊醇的安全性数据有限,主要基于开放标签和儿童德朗综合症的小型安慰剂对照临床试验。在这些研究中,将司替戊醇添加到慢性氯巴占治疗中,并未增加血清转氨酶升高的频率,并且没有出现临床上明显的肝损伤。长期使用司替戊醇与低比率的ALT和碱性磷酸酶升高有关,但在高达38%的病例中伴有γ-谷氨酰转肽酶(GGT)的增加。自从其广泛可用以来,尚未有关于司替戊醇肝毒性的已发表案例报告。因此,如果确实发生,由于司替戊醇引起的临床上明显的肝损伤必须很罕见。
Limited data are available on the safety of stiripentol, based mainly on open-label and small, placebo controlled clinical trials in children with Dravet syndrome. In these studies, addition of stiripentol to chronic clobazam therapy was not associated with an increased frequency of serum aminotransferase elevations, and there were no instances of clinically apparent liver injury. Long term therapy with stiripentol has been linked to low rates of ALT and alkaline phosphatase elevations but with increases in gamma glutamyl transpeptidase (GGT) in up to 38% of cases. Since its general availability, there have been no published case reports of stiripentol hepatotoxicity. Thus, clinically apparent liver injury due to stiripentol must be rare, if it occurs at all.
