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. Plaquenil and scleroderma Opthamologist plaquenil eye exam montgomery al Plaquenil heartburn 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. Chloroquine is a 9-aminoquinoline known since 1934. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections. Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best. 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.

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. 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.
