Dose findings of dihydroartemisinin in treatment of falciparum malaria. The Southeast Asian Journal of Tropical Medicine and Public Health. 1999 Mar; 30(1): 17-9http://imsear.searo.who.int/handle/123456789/32186The Southeast Asian Journal of Tropical Medicine and Public Health.Forty patients with uncomplicated P. falciparum malaria were respectively treated in an open randomized comparative study of dihydroartemisinin tablets given at total doses of 480 mg over 5 days and 640 mg over 7 days in a drug-resistant malaria endemic area in Hainan, China. The result showed that all patients were clinically cured. In 5-day and 7-day groups, the mean fever clearance times (FCT) were 26.1+/-10.2 and 21.1+/-11.8 hours respectively; the mean parasite clearance times (PCT) were 58.7+/-20.9 and 59.4+/-20.9 hours respectively, which showed no significant difference. 28-day follow-ups were accomplished on 39 and 37 cases respectively in two groups, the recrudescence rates were 20.5% (8/39) in 5-day group, while 2.7% (1/37) in 7-day group with significant difference (chi2=4.19, p<0.05). No clinical drug-related side effect was found in two groups during treatment.engAdministration, OralAdolescentAdultAgedAntimalarials --administration & dosageArtemisininsChildChinaDose-Response Relationship, DrugDrug ResistanceFever --parasitologyFollow-Up StudiesHumansMalaria, Falciparum --bloodMiddle AgedSesquiterpenes --administration & dosageTime FactorsClinical Trial
