    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).

    For chloroquine, the estimates of absorption rate constant, the total apparent volume of distribution, and elimination half-life of chloroquine are in agreement with previously reported values. The apparent elimination clearance is lower compared to previous studies. This is probably due to the use of different sample matrixes 26–41. 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 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

    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.

    In one study, serum concentrations of chloroquine appeared to decline in a biphasic manner and the serum half-life of the terminal phase increased with higher dosage of the drug. In this study, the terminal half-life of chloroquine was 3.1 hr after a single 250 mg oral dose, 42.9 hr after a single 500 mg oral dose. 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.
