It has been measured to be >99% in humans, rats, and dogs. Mechanism of Action of Primaquine Primaquine damage the mitochondria; the power house of parasite. It is believed that it is converted in the liver to an active quinone metabolite and probably exerts its activity by interfering with parasite mitochondrial function . Each of these metabolites were observed in the urine. [13], As of 2016, the US Centers for Disease Control and Prevention recommends the use of primaquine for primary prophylaxis prior to travel to areas with a high incidence of P. vivax, and for terminal prophylaxis (anti-relapse therapy) after travel.
