Biochem/physiol Actions

Tafenoquine has been generally generated for oral administration and drug absorption increases when taken along with food. It is known to possess a longer half life.
Tafenoquine is an antimalarial primaquine analog being investigated to treat and prevent Plasmodium vivax infections. It can eliminate both blood and liver stages of Plasmodium vivax. Tafenoquine has also been tested as a therapy for leishmaniasis.
