title: Comparison of antimalarial efficacy of artemisinin (qinghaosu) and arteether against Plasmodium cynomolgi B infection in monkeys.
abstract: Arteether (30:70 mixture of alpha and beta epimers) used as injectable intramuscular preparation (in neutralized ground-nut oil) had curative action at 5 mg/kg x 3 d against blood-induced Plasmodium cynomolgi B infection in rhesus monkeys, while the curative dose of artemisinin (qinghaosu) oil suspension was 10 mg/kg x 7 d or 20 mg/kg x 3 d. Parasite clearance with arteether was achieved within 24 h. Neither arteether nor artemisinin exhibited any causal prophylactic or radical curative action up to dose levels of 20 mg/kg against sporozoite-induced P. cynomolgi B infection in rhesus monkeys.
