The life cycle of malaria parasites. Sporozoites are introduced by a mosquito bite. They migrate to the liver, where they multiply into thousands of merozoites. The merozoites infect red blood cells and replicate, infecting more and more red blood cells. Some parasites form gametocytes, which are taken up by a mosquito, continuing the life cycle.

Primaquine is a medication used to treat and prevent malaria and to treat Pneumocystis pneumonia.

- Primaquine

The derivatives primaquine, tafenoquine and pamaquine have been tested for anti-malaria activity.

- 8-Aminoquinoline

Primaquine is an analog of pamaquine which was the first drug of the 8-aminoquinoline class; tafenoquine is another such drug.

- Primaquine

Treatment of P. vivax requires both treatment of blood stages (with chloroquine or artemisinin-based combination therapy) and clearance of liver forms with an 8-aminoquinoline agent such as primaquine or tafenoquine.
