Artesunate + Mefloquine

Armed Forces Research Institute of Medical Sciences, Thailand · FDA-approved active Small molecule

Artesunate kills malaria parasites by generating reactive oxygen species that damage parasite proteins and membranes, while mefloquine inhibits parasite heme polymerization and disrupts mitochondrial function.

Artesunate kills malaria parasites by generating reactive oxygen species that damage parasite proteins and membranes, while mefloquine inhibits parasite heme polymerization and disrupts mitochondrial function. Used for Uncomplicated malaria caused by Plasmodium falciparum, Malaria treatment in endemic regions, particularly Southeast Asia.

Mechanism of action

Artesunate, a semi-synthetic artemisinin derivative, acts as a fast-acting blood schizonticide that rapidly reduces parasite biomass through oxidative stress mechanisms. Mefloquine is a slower-acting quinoline antimalarial that concentrates in the parasite's food vacuole and prevents detoxification of heme, leading to parasite death. The combination provides complementary rapid and sustained parasite clearance with reduced risk of resistance.
