It contains tertiary amino group and when it is converted into . Now customize the name of a clipboard to store your clips. I. [3], Primaquine has not been studied extensively in people 65 and older so it is not known if dosing should be adjusted for this population. A: Bacterial vaginosis is also known as nonspecific vaginitis. Inhibition of protein synthesis is also observed, evidently as a secondary effect. The antimalarial activity of PQ against liver stages depends on host CYP2D6 status, whilst OH-PQm display direct, CYP2D6-independent, activity. Plasmodium vivax is more geographically dispersed than Plasmodium falciparum, with transmission occurring over a wider range of temperatures than for P.falciparum [], and at latitudes as far as 64 North [].

[2], Primaquine is primarily used to prevent relapse of malaria due to Plasmodium vivax and Plasmodium ovale. [6] Liver hypnozoites aside, primaquine can possibly eliminate P. vivax merozoites in bone marrow as a result of accumulation there of hydrogen peroxide. Pamaquine is more toxic and less efficacious than primaquine; therefore, pamaquine is no longer routinely used, and of the two, only primaquine is currently recommended by the World Health Organization.
