Metabolism: It undergoes metabolism in the liver. [1] Prior to this, it was understood that patients with vivax malaria would suffer from relapses, but there was no treatment that could prevent the relapses from occurring. Xm ng Nng - X Din Lm - Huyn Din Chu - Ngh An Hotline . Primaquine, an 8-aminoquinoline, is the only medication approved by the World Health Organization to treat the hypnozoite stage of Plasmodium vivax and P. ovale malaria. The early plasma half life varies from 3-10 days, because of tighttissue binding small amounts persist in body with terminal half life of 1-2 months. Capable of clearing the intra-hepatic schizonts and hypnozoites of Plasmodium vivax: //dailymed.nlm.nih.gov/dailymed/lookup.cfm?
