Tafenoquine is anti-malaria drug originated in Walter reed army institute of research and developed by GSK and 60 Degrees Pharmaceuticals. In 2018 United States Food and Drug Administration (FDA) approved single dose tafenoquine for the radical cure (prevention of relapse) of Plasmodium vivax malaria.
Tafenoquine, an 8-aminoquinoline antimalarial, is active against all the stages of Plasmodium species that include the hypnozoite (dormant stage) in the liver. Studies in vitro with the erythrocytic forms of Plasmodium falciparum suggest that tafenoquine may exert its effect by inhibiting hematin polymerization and inducing apoptotic like death of the parasite. In addition to its effect on the parasite, tafenoquine causes red blood cell shrinkage in vitro. Tafenoquine is active against pre-erythrocytic (liver) and erythrocytic (asexual) forms as well as gametocytes of Plasmodium species that include P. falciparum and P. vivax. The activity of tafenoquine against the pre-erythrocytic liver stages of the parasite, prevents the development of the erythrocytic forms of the parasite.
