代谢
在肝脏中通过细胞色素P450同工酶可变地代谢为活性三嗪代谢物,环桂酸。这种前瞻素的变量代谢在亚洲和非洲易患疟疾的人群中可能具有深远的重要临床意义。使用前瞻素预防可能对这些人无效,因为他们可能无法达到足够的治疗水平,即使是在多次剂量之后。
Variably metabolized in the liver by cytochrome P450 isoenzymes to the active triazine metabolite, cycloguanil. This variable metabolism of proguanil may have profound clinical importance in poor metabolizers such as the Asian and African populations at risk for malaria infection. Prophylaxis with proguanil may not be effective in these persons because they may not achieve adequate therapeutic levels of the active compound, cycloguanil, even after multiple doses.
