Six patients with uncomplicated falciparum malaria received artesunate for 5 days. Plasma concentrations of artesunate and dihydroartemisinin were determined by high-performance liquid chromatography with electrochemical detection. The concentrations of dihydroartemisinin in plasma 2 h after a dose showed a time-dependent decline. Concentrations of artesunate in plasma especially after the last dose, were very low. Despite this, all patients responded with a fast recovery.
6例无并发症的恶性疟患者接受了5天的青蒿琥酯治疗。采用高效液相色谱-电化学检测法测定血浆中青蒿琥酯和双氢青蒿素的浓度。给药后2小时血浆中双氢青蒿素浓度呈时间依赖性下降。血浆中青蒿琥酯浓度,尤其是最后一剂后浓度非常低。尽管如此,所有患者均迅速康复。
