Antimalarial medication multi-drug resistant "P. falciparum". It is a very potent blood schizonticide with a long half-life. It is thought to act by forming toxic heme complexes that damage parasitic food vacuoles. Mefloquine is effective in prophylaxis and for acute therapy. It is now used solely for the prevention of resistant strains of "P. falciparum" (usually combined with Artesunate) despite being effective against "P. vivax", "P. ovale" and "P. marlariae". Chloroquine/proguanil or sulfa drug-pyrimethamine combinations should be used in all other plasmodia infections. The major commercial manufacturer of mefloquine-based malaria treatment is Roche Pharmaceuticals, which markets the drug under the trade name
