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. Hydroxychloroquine 200 mg oral tab Will plaquenil help osteoarthritis Coming off hydroxychloroquine Chloroquine also is taken up into the acidic food vacuoles of the parasite in the erythrocyte. It increases the pH of the acid vesicles, interfering with vesicle functions and possibly inhibiting phospholipid metabolism. In suppressive treatment, chloroquine inhibits the erythrocytic stage of development of plasmodia. 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. This paper presents the current state of knowledge on chloroquine disposition, with special emphasis on stereoselectivity and microsomal metabolism. In addition, the impact of the patient’s physiopathological status and ethnic origin on chloroquine pharmacokinetics is discussed. In humans, chloroquine concentrations decline multiexponentially. The drug is extensively distributed, with a. 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.

SULLIVAN" Sections of Biochemistry and Pathology, Sterling-Winthrop Research Institute, Rensselaer, New York 12144 Received July 10, 1964 Chloroquine3 CQ was first prepared in this country in quantity 20. Chloroquine was a potent inhibitor of metoprolol metabolism mediated by CYP2D in rat and human liver microsomes though in human microsomes the drug was two orders of magnitude less potent as an inhibitor. Also, chloroquine, at doses comparable with humans on a per weight basis, inhibited this activity in anesthetized rats.
