    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.

Denis Projean, Bruno Baune, Robert Farinotti, Jean-Pierre Flinois, Philippe Beaune, Anne-Marie Taburet and Julie Ducharme. 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. Cimetidine can inhibit the metabolism of chloroquine, increasing its plasma level. Concomitant use of cimetidine should be avoided. Ampicillin. In a study of healthy volunteers, chloroquine significantly reduced the bioavailability of ampicillin. An interval of at least two hours between intake of this agent and chloroquine should be observed.

    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.

    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. Abstract. In humans, the antimalarial drug chloroquine CQ is metabolized into one major metabolite, N-desethylchloroquine DCQ. Using human liver microsomes HLM and recombinant human cytochrome P450 P450, we performed studies to identify the P450 isoforms involved in the N-desethylation of CQ. 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.

    Let me tell you what weaning down from Plaquenil is like. Anita- I had always heard that too - that even if you stopped it, it would take a long time before it was out of your system. I still believe this to be true, but I am convinced now that plaquenil must have multiple modes of action, one being long term effects, and one being something happening in the short term.
