Mean plasma concentration-time profiles of artesunate (AS, left) and dihydroartemisinin (DHA, right), an active metabolite of AS, measured by LC-MS/MS (markers) and computer pharmacokinetic fitting curves (solid-line) following multiple intravenous dosage with 2 min short-term infusion of AS at 2 (top), 4 (middle), and 8 (bottom) mg/kg in healthy volunteers. (n = 6 for each dose cohort).
