    What is the half life of chloroquine


    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 volume of distribution of 200 to 800 L/kg when calculated from plasma concentrations and 200 L/kg when estimated from whole blood data (concentrations being 5 to 10 times higher).

    Half-life T ½ In healthy individuals, the plasma half-life of chloroquine is 72 to 120 hours. One study indicated that chloroquine declines in a biphasic manner, with the terminal phase half-life increasing with increasing doses, as follows 3.1 hours after a single 250-mg oral dose, 42.9 hours after a single 500-mg oral dose, and 312 hours after a single 1-g oral dose. 10 Keep in mind that, depending on the used cell line, autophagy will have a rather hyperbolic character meaning that even when using chloroquine, depending on the time you end the experiment autophagy may seem more or less. This is why a small time course pre-study is advised 2, 4, 8, 16, 24, 48 hours. The shorter half-life of S +-chloroquine appears secondary to its faster clearance. Blood concentrations of the S +-forms of desethylchloroquine always exceeded those of the R −-forms, pointing to a preferential metabolism of S +-chloroquine.

    Following administration chloroquine is rapidly dealkylated via cytochrome P450 enzymes (CYP) into the pharmacologically active desethylchloroquine and bisdesethylchloroquine. Chloroquine is 60% bound to plasma proteins and equally cleared by the kidney and liver.

  2. 3-hydroxychloroquine
  3. Feb 17, 2015 A metabolite of chloroquine – hydroxycloroquine – has a long half-life of 32–56 days, so it's not a good idea to use a single dosage past one month anyway. Using CP in a display tank or any tank with rock/substrate almost always fails to eradicate the parasites. I believe this to be due to absorption.

    Oct 01, 2018 Chloroquine overdose is a life-threatening emergency and should be managed with cardio-respiratory and hemodynamic support, monitoring of potassium along with management of arrhythmias and convulsions, as necessary. Half-life. Usually 72–120 hours. a. Serum concentrations decline in a biphasic manner and terminal half-life increases with increasing doses. a Terminal half-life is 3.1 hours after a single 250-mg oral dose, 42.9 hours after a single 500-mg oral dose, and 312 hours after a single 1-g oral dose. a. Stability Storage Oral Tablets Prolonged half life of several weeks 50% of chloroquine is excreted unchanged; Resuscitation Coma Prompt intubation and ventilation, if acidaemia exists, give sodium bicarbonate 1 – 2 mmol/Kg IV to prevent further toxicity during intubation. End goals should be a narrow QRS 100ms and a pH 7.45

    Chloroquine Indications, Side Effects, Warnings - If a child takes chloroquine by accident, get medical help right away. If you are 65 or older, use chloroquine with care. You could have more side effects. Tell your doctor if you are pregnant or plan on getting pregnant. You will need to talk about the benefits and risks of using chloroquine while you are pregnant.
