CLINICAL PHARMACOLOGY
Primaquine phosphate is an 8-aminoquinoline 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
Primaquine phosphate is indicated for the radical cure (prevention of
relapse) of vivax malaria.
CONTRAINDICATIONS
Primaquine phosphate is contraindicated in acutely ill patients
suffering from systemic disease
manifested by tendency to granulocytopenia, such as rheumatoid
arthritis and lupus erythematosus. The
drug is also contraindicated in patients receiving concurrently other
potentially hemolytic drugs or
depressants of myeloid elements of the bone marrow.
Because quinacrine hydrochloride appears to potentiate the toxicity of
antimalarial compounds which

patients receiving primaquine is
contraindicated. Similarly, Primaquine should not be administered to
patients who have receiv
