Primaquine

Primaquine is an antimalarial medication primarily used to treat and prevent relapses of malaria caused by Plasmodium vivax and Plasmodium ovale. It is also effective in preventing malaria transmission by targeting the liver stage of the parasite. Primaquine is usually prescribed in combination with other antimalarial drugs to ensure complete eradication of the infection. It works by disrupting the parasite's life cycle in the liver, preventing recurrence. This medication is essential in malaria elimination programs and is widely recommended by health organizations for its effectiveness in clearing dormant parasites from the body.
