How does Primaquine treat malaria?

Malaria is caused by parasites transmitted into a host, usually from a mosquito bite. When the parasites enter the body, they first enter the liver cells where they multiply before entering the red blood cells. Known as the blood form of the parasite, this stage causes malaria's symptoms as the organism enters and destroys the red blood cells while releasing more offspring into the blood. Primaquine works by killing some of these parasites, primarily Plasmodium vivax and Plasmodium ovale, before they reach the blood form.
