Peak plasma mefloquine concentrations in three patients who vomited within 2 h of treatment were 725, 9 ng ml-1. There was no significant difference between plasma and whole blood mefloquine concentrations during the first 48 h of treatment.

    Chloroquine is rapidly and almost completely absorbed from the bowel following oral administration. Peak plasma concentrations of chloroquine are reached within 4–12 hours, but it takes 4–6 weeks for plasma concentrations to stabilise; therefore, it will take 2–3 months to see a therapeutic effect. Peak level was reached in 1-8 h after the first dose of 10 mg/kg and the peak concentrations ranged between 65 and 263 ng/ml. Chloroquine concentration declined slowly in plasma after stopping drug administration so that the concentration at the seventh day was 37.5% of the concentration on the third day. The apparent half-life was 3-4 days. Chloroquine 600 mg base was administered orally and timed blood samples were obtained for determination of plasma concentrations. The results suggest that the AUC and peak plasma levels were significantly higher when chloroquine was administered together with food, although the rate of absorption was not different.
