    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.

Usual Adult Dose for Malaria. 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. 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 a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. It is also occasionally used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. P vivax and P ovale have dormant stages hypnozoites in the liver, and the treatment of an episode of malaria must include eradication of these. The classic treatment is a 3-day course of chloroquine, followed by a 14-day course of primaquine. A shorter course of 5 days of primaquine, started with chloroquine. 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.
