| Summary: | Thirty-three female patients suffering from acute uncomplicated falciparum malaria were treated with intramuscular artemether for 5 days during May-October 1990. Fourteen patients received 160 mg as an initial dose, followed by 80 mg daily for 4 days. Nineteen patients with low body weight (mean weight of 36.5 kg) were given artemether at 3.2/kg as a loading dose and followed by 1.6 mg/kg/dose for another 4 days. The geometric mean of parasitemia was 17.378/μl (range 640-234,720). The mean fever (FCT) and parasite clearance time (PCT) were 41.8 and 49.4 hours, respectively. Two patients had probable intercurrent infection with FCT of over 7 days. Thirty-one patients had completed the 28-day follow-up. The cure rate was 90.3% (28/31). Three patients had RI type of response. Mild and transient adverse effects were experienced in eleven patients; these consisted of pain at the injection sites, vomiting, dizziness, abdominal pain, palpitation and diarrhea. These symptoms may in part be due to symptom complex of malaria. The MC of chloroquine, quinine, quinidine and mefloquine was performed in all patients but only 25 isolates were successfully cultured and tested. The MIC of all tested drugs were shown to be higher than that of previous studies, suggesting that there is a rapid increase of mefloquine resistant strains of falciparum malaria. In conclusion, artemether proves to be effective against multiple drug resistant falciparum malaria (including mefloquine resistant strains) and can be considered as an alternative antimalarial to mefloquine. The drug was well tolerated in female patients with mild and transient side-effects. Further studies should be carried out to find the optimum dosage regmen to achieve the cure rate of 100% which is needed in areas with multiple drug resistant strains of falciparum. |
