    -Suppressive therapy should continue for 8 weeks after leaving the endemic area.

    Chloroquine is extensively distributed with an enormous total apparent volume of distribution Vd more than 100 L/kg, and a terminal elimination half-life of 1 to 2 months. As a consequence, distribution rather than elimination processes determine the blood concentration profile of chloroquine in patients with acute malaria. 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. In order to determine the pharmacokinetic disposition of chloroquine CQ and its active metabolite, desethylchloroquine DECQ, when administered as intermittent presumptive treatment in pregnancy IPTp for malaria, 30 Papua New Guinean women in the.

    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.

    Before the administration of chloroquine, the patient had only a mild skin erythema in the irradiated area, which was consistent with the radiotherapy dose she had received. On day 3 of chloroquine therapy, she developed localized brisk bullous eruptions in the irradiated area, which developed into a patch of fulminant moist desquamation. The kinetics of uptake of chloroquine into isolated rat hepatocytes were studied to further investigate whether they are consistent with accumulation of chloroquine at therapeutic concentrations that is predominantly due to lysosomal trapping. Eight healthy volunteers who had not taken chloroquine 2 to 12 months previously participated in a single dose study designed to evaluate the pharmacokinetics of chloroquine and some of its metabolites. Each subject received two tablets of chloroquine sulfate 300 mg base only.
