Artemether + Lumefantrine is a fixed-dose combination antimalarial medication used to treat uncomplicated Plasmodium falciparum malaria. Artemether, a fast-acting artemisinin derivative, quickly reduces the number of parasites in the blood, while Lumefantrine, a longer-acting antimalarial, clears remaining parasites and helps prevent recurrence. The combination is effective, well-tolerated, and recommended by the WHO as a first-line treatment in areas with drug-resistant malaria.
