    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).

    It takes about 5.5 half life's before the drug is totally out of your system so if we used 3 days as the elimination half life it being the maximum time given, then it would take 16.5 days 5.5 x 3 days for both the ingredients of Malarone to be cleared from your system. 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. The plasma half-life of chloroquine in healthy individuals is generally reported to be 72-120 hr. 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.

    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.

    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 In the same study, the plasma peak concentration was. 50.3 ng/mL reached in 3.74 hours with a half-life of 2963 hours 123.5 days. Urine hydroxychloroquine levels were still detectable after 3 months with approximately 10% of the dose excreted as the parent drug. Summary. Chloroquine is an anti-malarial drug available at pharmacies for people traveling to area with malaria risks. Note based on a RGCC chemosensitivity analysis I have seen at a German clinic, Hydroxychloroquine has been effective in killing the cancer cells of 5 out 7 patients that were tested.
