GENERAL DESCRIPTION & APPLICATIONS

Mefloquine is a modified 4-quinolonemethanol compound with the chemical designation of DL-erythro-alpha-2-Piperidyl-2,8-bis(trifluoromethyl)-4-quinolinemethanol. Malaria is one of leading re-emerging infectious disease due to murative malarial parasite developed resistance to chloroquine. It is effective against chloroquine-resistant strains such as Plasmodium falciparum and P. vivax malaria. Mefloquine hydrochloride is a white to almost white crystalline compound, slightly soluble in water; administered orally. Mefloquine molecules include:
Mefloquine
