110 patients with P. falciparum malaria and no complications from the Brazilian Amazon region were treated with the association tetracycline hydrocloride (1 g/d during 7 days) and quinine sulphate (1.5 or 2 g/d during 3 or 4 days) at the beginning of treatment. All patients were followed for at least 7 days and no blood parasites were detected ont the 7th day. Seventy- five patients could be followed for 28 days or longer and 4 of them (5.3%) showed parasitemia again. These results support the efficacy of the association quinineplus tetracycline in the treatment of P. falciparum malaria infections from the Amazon region.
