    Chloroquine. used in areas with low drug resistance; mefloquine. used in areas with high rates of chloroquine resistance; atovaquone/proguanil. used in areas with high rates of chloroquine resistance; primaquine. used to kill latent hypnozoites in Plasmodium vivax and Plasmodium ovale infection; intravenous quinidine or artesunate A chloroquine dose of 600 mg base = 1,000 mg salt should be given initially, followed by 300 mg base = 500 mg salt at 6, 24, and 48 hours after the initial dose for a total chloroquine dose of 1,500 mg base =2,500 mg salt. 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.

    Approved indication: For acute attacks of malaria due to P vivax, P malariae, P ovale, and susceptible strains of P falciparum CDC Recommendations: Chloroquine-sensitive uncomplicated malaria (Plasmodium species or species not identified): 600 mg base (1 g salt) orally at once, followed by 300 mg base (500 mg salt) orally at 6, 24, and 48 hours Total dose: 1.5 g base (2.5 g salt) Comments: -For the treatment of uncomplicated malaria due to chloroquine-sensitive P vivax or P ovale, concomitant treatment with primaquine phosphate is recommended. 60 kg or more: 1 g chloroquine phosphate (600 mg base) orally as an initial dose, followed by 500 mg chloroquine phosphate (300 mg base) orally after 6 to 8 hours, then 500 mg chloroquine phosphate (300 mg base) orally once a day on the next 2 consecutive days Total dose: 2.5 g chloroquine phosphate (1.5 g base) in 3 days Less than 60 kg: First dose: 16.7 mg chloroquine phosphate/kg (10 mg base/kg) orally Second dose (6 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Third dose (24 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Fourth dose (36 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Total dose: 41.7 mg chloroquine phosphate/kg (25 mg base/kg) in 3 days Comments: -Concomitant therapy with an 8-aminoquinoline compound is necessary for radical cure of malaria due to P vivax and P malariae.

  5. 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.

    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. Towards an in vitro model of Plasmodium hypnozoites suitable for drug discovery. Failure to detect hypnozoites in hepatic tissue containing exoerythrocytic schizonts of Plasmodium knowlesi. In this stage, some species of Plasmodium can form hypnozoites, which can remain hidden in the liver for many weeks or years. Emerging resistance to chloroquine CQ by Plasmodium vivax threatens the health of the hundreds of millions of people routinely exposed to the risk of infection with this organism. CQ has been the first-line therapy for vivax malaria since 1946 32, 115. Plasmodium falciparum developed resistance to CQ in the 1950s, and today it occurs globally.
