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 phosphate during pregnancy Plaquenil and sunburn Plaquenil and diarrhea 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 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. IN VITRO METABOLISM OF CHLOROQUINE IDENTIFICATION OF CYP2C8, CYP3A4, AND CYP2D6 AS THE MAIN ISOFORMS CATALYZING N-DESETHYLCHLOROQUINE FORMATION. Denis Projean, Bruno Baune, Robert Farinotti, Jean-Pierre Flinois, Philippe Beaune, Anne-Marie Taburet and Julie Ducharme. 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.

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. Recommendations on Screening for Chloroquine and.. IN VITRO METABOLISM OF CHLOROQUINE IDENTIFICATION OF.. Dose Optimization of Chloroquine by Pharmacokinetic Modeling.. 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. Find patient medical information for Chloroquine Oral on WebMD including its uses, side effects and safety, interactions, pictures, warnings and user ratings. 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.
