If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder sym Radical cure in P. vivax infection is, killing of exoerythrocytic stage of parasites known as hypnozoites, which are responsible for relapse of malaria. If only chloroquine or other agents for clinical cure is used, it will have no effects on hypnozoites and lead to recurrence of malaria again, later on, without new infection by mosquito bite. Primaquine was officially licensed as an anti-malarial drug by the FDA in 1952. It has remained the only FDA licensed drug capable of clearing the intra-hepatic schizonts and hypnozoites of Plasmodium vivax. This update and review focuses on five major aspects of primaquine use in treatment of vivax malaria, namely a evidence of efficacy of primaquine for its current indications; b.

    Plasmodium vivax is the most widespread malaria parasite. It has a dormant stage in the human liver, which makes it difficult to eradicate. It is proposed that a relapse of vivax malaria, besides being genetically determined by the specific strain, is induced by the bites of uninfected vectors. Chloroquine is an anti-malaria medicine that works by interfering with the growth of parasites in the red blood cells of the human body. Parasites that cause malaria typically enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia. Chloroquine is used to treat and to prevent. The hypnozoites are insensitive to atovaquone-proguanil, which is active against liver stage schizonts and to chloroquine 4. Relapses indicating a dormant stage occur also in Plasmodium ovale and in the simian Plasmodium cynomolgi, Plasmodium fieldi, Plasmodium simiovale and Plasmodium schwetzi infections 5 – 7.
