Primaquine, introduced in 1950, for preventing relapse and sterilizes infectious sexual plasmodia. Methods: A retrospective study was performed for 610 patients (250 were male and 360 were female), (all ages) to study the efficacy of Primaquine in the treatment of falciparum malaria after receiving this drug for five days. Results: Five hundred and ninety three patients (97.2 %) were completely recovered from malaria within 3 to 5 days after receiving Primaquine tablets. Conclusion: In our opinion Primaquine should become the first line as antimalarial drug soon later for uncomplicated malaria, because of its high efficiency against infections with Plasmodiumfalciparum and P.vivax active stages.other
