BALB/c mice with established visceral infection caused by the intracellular protozoan Leishmania donovani were treated with oral atovaquone for 7 days. Treatment with 100 mg/kg of body weight per day was optimal and halted parasite replication in the liver. In mice treated with atovaquone, the effect of a suboptimal dose of pentavalent antimony was converted from partially leishmanistatic to leishmanicidal. These results demonstrate the in vivo antileishmanial effect of atovaquone and suggest a potential role for this oral agent in visceral leishmaniasis as an adjunct to conventional antimony treatment.
对已建立由细胞内原生动物杜氏利什曼原虫引起的内脏感染的BALB/c小鼠,口服阿托伐醌治疗7天。每天100 mg/kg体重的治疗剂量最佳,可使肝脏中的寄生虫复制停止。在用阿托伐醌治疗的小鼠中,次优剂量的五价锑的作用从部分抑制利什曼原虫转变为杀利什曼原虫。这些结果证明了阿托伐醌的体内抗利什曼原虫作用,并表明这种口服药物在内脏利什曼病中作为传统锑治疗辅助药物的潜在作用。
