Description Malaria is a protozoan disease that places an enormous burden on human health in endemic areas around the world. The 2020 World Health Organization malaria report indicates a 60% decrease in the global malaria fatality rate between 2000 to 2019.[L30618] Despite this, malaria remains a significant cause of morbidity and mortality; 90% of deaths from malaria occur in Africa. Individuals at the highest risk for malaria are those in disease naïve populations, children under age 5, refugees in Central and Eastern Africa, nonimmune civilian and military travelers, pregnant women, and immigrants traveling to their place of origin.[L30623] Mefloquine, commonly known as Lariam, is an antimalarial drug used for the prevention and treatment of malaria caused by infection with Plasmodium vivax and Plasmodium falciparum. The drug was initially discovered by the Walter Reed Army Institute of Research (WRAIR) during a malaria drug discovery program between 1963 until 1976. It was approved by the FDA in 1989, and was first marketed by Hoffman Laroche.[A226838] This drug has been the subject of widespread controversy due to concerns regarding neurotoxic effects; product information warns of potential serious neuropsychiatric effects.[A226838,L8953]
Indications and Usage Mefloquine is indicated for the treatment of mild to moderate cases of malaria caused by Plasmodium falciparum and Plasmodium vivax. It is effective against chloroquine-resistant forms of Plasmodium falciparum. Mefloquine is also indicated for the prophylaxis of malaria caused by Plasmodium falciparum and Plasmodium vivax, including chloroquine-resistant forms of Plasmodium falciparum.[L8953]
