How Artesunate + Mefloquine Tablet works

Artesunate works quickly by creating unstable molecules inside the malaria parasite that damage its proteins and other essential parts, killing it fast. Mefloquine works more slowly by interfering with how the parasite breaks down a substance called haem, causing toxic byproducts to build up and kill the parasite. Together they clear the parasite from the blood and lower the chance the infection will come back or become drug-resistant.
