    THE COMPLETE CONTENTS OF THIS LEAFLET BEFORE PRESCRIBING PRIMAQUINE PHOSPHATE. DESCRIPTION. Primaquine phosphate is 8-4-Amino-1-methylbutyl amino-6-methoxyquinoline phosphate, a synthetic compound with potent antimalarial activity. Each tablet contains 26.3 mg of Primaquine phosphate equivalent to 15 mg of primaquine base. Dec 12, 2011 Primaquine, an 8-aminoquinoline, has been approved for treatment of malaria since 1952 by the Food and Drug Administration FDA, United States. Six decades after its official licensing, primaquine still holds a unique and unchallenged place in anti-malarial regimens of cure and prophylaxis. Primaquine phosphate is an 8-amino-quinoline compound which eliminates tissue exoerythrocytic infection. Thereby, it prevents the development of the blood erythrocytic forms of the parasite which are responsible for relapses in vivax malaria. Primaquine phosphate is also active against gametocytes of Plasmodium falciparum. INDICATIONS AND USAGE
