title: A comparative study of the schizontocidal efficacy and safety of artemether versus chloroquine in uncomplicated malaria.
abstract: Forty-seven patients with uncomplicated falciparum malaria were randomly assigned to receive either artemether (n = 24), 9.6 mg/kg body weight intramuscularly over five days or chloroquine (n = 23), 25 mg/kg body weight orally. Patients were kept in hospital for seven days followed by review on days 14, 21 and 28. Five patients on chloroquine were withdrawn before day seven due to treatment failure. Of the remaining patients, parasite clearance time was 33.0 +/- 13.6 hours for the artemether group and 63.3 +/- 14.7 hours for patients on chloroquine (p < 0.001). No significant difference was recorded in fever clearance time between the two groups of patients. Recrudescence rate for patients on artemether was 14.3 pc compared to 57.1 pc for the chloroquine group (p < 0.05). No major adverse events were recorded for either treatment group although five patients on artemether had a transient spike of temperature after clearance of parasitaemia. In conclusion, our study has shown that no major adverse events were experienced by patients on artemether and the rate of parasite clearance for the artemether group was superior to that of patients on chloroquine.
