Mef Q
Mef Q is an antimalarial drug that is used to prevent or treat malaria. It is a synthetic mescaline-related compound classified as a 4-quinolinemethanol group.

It is especially used to prevent and treat malaria caused by Plasmodium falciparum, the parasite that causes the most severe form of malaria in humans.
