    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.

    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. During model development and validation step 1, model performance depends largely on the certainty of the model input parameters describing CQ absorption, distribution, and metabolism and elimination. 58 When using literature-reported PK parameters for absorption ka, distribution Vss, and elimination clearance, the model performance was. 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.

    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.

  4. Chloroquine has a high affinity for tissues of the parasite and is concentrated in its cytoplasm. As a weak base, it increases the pH of the intracellular lysosome and endosome. A more acidic medium in these organelles is needed for the parasite to affect mammalian cells. As a result, chloroquine inhibits growth and development of parasites.

    Oct 20, 2012 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. The inhibitory effect of chloroquine and quinine on the formation and time-course of the PQ 5,6-orthoquinone generated from racemic PQ a and its individual enantiomers b, c by CYP2D6; and on the formation of primaquine alcohol from CYP2D6-catalyzed metabolism of racemic PQ d and its enantiomers e, f. Each point represents values mean. 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.
