Mechanism of action

Artemether, an artemisinin derivative, rapidly reduces parasite biomass by generating reactive oxygen species that damage parasite membranes and proteins. Lumefantrine, a biguanide-like compound, inhibits parasite heme polymerization and prevents detoxification of toxic heme, providing sustained parasite suppression. Together they achieve fast initial parasite clearance followed by complete elimination.
