Chloroquine itself can cause reduced kidney function of up to 10% of patients, especially in those over 60 years of age. Chloroquine and hydroxychloroquine have the same indications and usage, although the dosage regimens are different. Chloroquine african Plaquenil and valley fever Chloroquine paludisme In this study, the rate of absorption of chloroquine was unaffected by the presence of food in the GI tract however, peak plasma concn of chloroquine and areas under the plasma concentration-time curves were higher when 600 mg of the drug was administered with food than when the same dose was administered without food. Parenteral administration of chloroquine should be considered when there is no expectation of resistance, when the patient is unable to take drugs orally and when neither quinine nor quinidine is available. Excessively rapid administration results in toxic peak plasma concentrations and a danger of fatal cardiovascular collapse. Plasma and packed red‐cell concentrations of chloroquine, electrocardiographic intervals, arterial blood pressure and pulse were measured at frequent intervals. 3. Peak plasma concentrations at the end of the infusion ranged from 979 to 2,900 ng ml‐1 in the malaria patients. In the group of healthy subjects the range was 550‐2,200 ng. Chloroquine should be used with caution in patients with known porphyria cutanea tarda. Renal impairment results in higher blood levels of chloroquine and therefore an increased toxicity risk. Chloroquine peak plasma concentrations Chloroquine analogues in drug discovery new directions of., WHO Model Prescribing Information Drugs Used in Parasitic. Chloroquine ovarian cancer We compared the pharmacokinetics of chloroquine in pregnant and nonpregnant women treated for Plasmodium vivax malaria. Twelve pregnant women and 15 nonpregnant women of child-bearing age with acute P. vivax malaria were treated with 25 mg chloroquine base/kg over 3 days on the northwestern border of Thailand. Blood concentrations of chloroquine and desethylchloroquine were measured. Chloroquine pharmacokinetics in pregnant and nonpregnant women with.. Pharmacokinetics of chloroquine in Thais plasma and red‐cell.. Pharmacokinetics of chloroquine in Thais plasma and red-cell.. Linear pharmacokinetics is so-called because the graph of the relationship between the various factors involved dose, blood plasma concentrations, elimination, etc. gives a straight line or an approximation to one. For drugs to be effective they need to be able to move rapidly from blood plasma to other body fluids and tissues. The peak plasma concentration after an oral dose of chloroquine is 3–12 h 10, 32, 67. Thirty-three to 70 % of the drug in plasma is protein-bound 2, 32, 38, 75, 79, 80. The effects of hypoalbuminemia and altered immunoglobulin composition in patients taking 4AQs are not well understood 80.
