    Metabolism of chloroquine


    Please review the following URL and make sure that it is spelled correctly. The administration of chloroquine or hydroxychloroquine to albino and pigmented (hooded) rats at a daily dosage of 40 mg/kg produces a rapid rise in tissue concentrations of the drugs during the first month of medication, but comparatively little further rise when the medications are continued for two additional months.

    Chloroquine undergoes appreciable degradation in the body. The main metabolite is desethylChloroquine, which accounts for one fourth of the total material appearing in the urine;bisdesethylChloroquine, a carboxylic acid derivative, and other metabolic products as yet uncharacterized are found in small amounts. The development of an analytic method which determines all of the known acidic and basic metabolites of chloroquine made possible a study of its metabolism in man during and after oral dosage at 310 mg/day for 14 days. Plasma levels and urinary excretion reached apparent plateaus at 125 µg/day, respectively, within 10 days. When medication was terminated, plasma levels and urinary excretion.

    However, rats degrade the latter compound more extensively, so that their total mean tissue content of 4-aminoquinoline bases is greater than 30 mg/kg at that time. The mean tissue concentration of chloroquine at 1 month is about 100 mg/kg, compared to about 30 mg/kg for hydroxychloroquine.

  3. Chloroquine and ammonium chloride, by virtue of their basic properties, have been shown to raise endocytic and lysosomal pH and thereby interfere with normal iron metabolism in a variety of cell types, including mononuclear phagocytes.

    Abstract. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. The present study concerns the effect of the lysosomotropic drug chloroquine on the uptake and metabolism of 35Scystine in vitro by normal human fibroblasts and those from patients suffering from the lysosomal storage disease cystinosis. When the cells were cultured with 35Scystine for periods in excess of 4 h, it was found that chloroquine considerably increased up to 30-fold the. 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 second or third trimester of pregnancy and 30 age-matched nonpregnant women were administered three daily doses of 450 mg CQ 8.5 mg/kg of body.

    Plaquenil Dosage Guide - In a small percentage of patients, side effects may require temporary reduction of the initial dosage. Maintenance adult dosage When a good response is obtained, the dosage may be reduced by 50 percent and continued at a maintenance level of 200 mg to 400 mg 155 to 310 mg base daily, administered as a single daily dose or in two divided doses.

This multitiered approach should lead to diagnosis or exclusion of the diagnosis of AIHA in patients with SLE. Patients with AIHA present with constitutional signs and symptoms of anaemia, including fatigue and dyspnoea on exertion.
