Guide to Malaria Pharmacology Comments
Primaquine is effective against all exoerythrocytic forms of the malaria parasite, including the hypnozoite and is also active against the sexual blood stage (gametocytes). Primaquine was, until the approval of tafenoquine in 2018, the only licensed drug available for terminal prophylaxis to prevent relapse or delayed-onset clinical presentation of P. vivax and P. ovale malaria.
