Mefloquine, sold under the brand names Lariam among others, is a medication used to for the treatment of mild to moderate acute malaria caused by Mefloquineuine-susceptible strains of Plasmodium falciparum (both chloroquine-susceptible and resistant strains) or by Plasmodium vivax. Also for the prophylaxis of Plasmodium falciparum and Plasmodium vivax malaria infections, including prophylaxis of chloroquine-resistant strains of Plasmodium falciparum. Mefloquine acts as a blood schizonticide. Mefloquine is active against the erythrocytic stages of Plasmodium species. However, the drug has no effect against the exoerythrocytic (hepatic) stages of the parasite. Mefloquine is effective against malaria parasites resistant to chloroquine. Mefloquine is a chiral molecule. According to some research, the (+) enantiomer is more effective in treating malaria, and the (-) enantiomer specifically binds to adenosine receptors in the central nervous system, which may explain some of its psychotropic effects.

Artenimol (dihydroartemisinin) is a derivate of antimalarial compound artemisinin. Artenimol (dihydroartemisinin) is able to reach high concentrations within the parasitized erythrocytes. Its endoperoxide bridge is thought to be essential for its antimalarial activity, causing free-radical damage to parasite membrane systems including: • Inhibition of falciparum sarcoplasmic-endoplasmic reticulum calcium ATPase, • Interference with mitochondrial electron transport • Interference with parasite transport proteins • Disruption of parasite mitochondrial function. Dihydroartemisinin in combination with piperaquine tetraphosphate (Eurartesim, EMA-approved in 2011) is indicated for the treatment of uncomplicated Plasmodium falciparum malaria. The formulation meets WHO recommendations, which advise combination treatment for Plasmodium falciparum malaria to reduce the risk of resistance development, with artemisinin-based preparations regarded as the ‘policy standard’. However, experimental testing demonstrates that, due to its intrinsic chemical instability, dihydroartemisinin is not suitable to be used in pharmaceutical formulations. In addition, data show that the currently available dihydroartemisinin preparations fail to meet the internationally accepted stability requirements.
