The drug combination atovaquone/proguanil (INNs, trade names Malarone, Malanil) is an antimalarial medication used in both the treatment and prevention of malaria. Atovaquone alone is not indicated for treatment or prevention of malaria as monotherapy (i.e., without proguanil). Atovaquone/proguanil has been commercially available from GlaxoSmithKline since 2000, and its patent expired in 2013. Malarone has applications for treating chloroquine-resistant malaria.
