Mechanism of action

Mefloquine acts as a blood schizonticide, disrupting the malaria parasite's ability to metabolize hemoglobin and maintain ion balance within infected red blood cells. Artesunate, a fast-acting artemisinin derivative, generates reactive oxygen species that damage parasite proteins and DNA. The combination leverages their different mechanisms and pharmacokinetics to provide rapid parasite clearance and reduce the emergence of drug-resistant strains.
