    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).

    Desethylchloroquine and bisdesethylchloroquine concentrations reach 40 and 10% of chloroquine concentrations, respectively; both chloroquine and desethylchloroquine concentrations decline slowly, with elimination half-lives of 20 to 60 days. Both parent drug and metabolite can be detected in urine months after a single dose.

Dec 23, 2012 Given what we know about chloroquine, we can now determine its half-life. Chloroquine has an extremely high volume of distribution 12,950 L. It also has a high clearance rate of 45 L/hour. This means its half-life is roughly 200 hours! If you have been taking chloroquine and your blood has reached a steady state concentration, it will take over 8 days for the plasma concentration to decrease by 50%. In the world of medicine, this is a very long time.

    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.

Hydroxychloroquine HCQ is nearly identical in structure to CQ and has a similar mechanism of action and therapeutic efficacy in rheumatological and infectious diseases. Like CQ, it also has a long half-life, and a very high volume of distribution.

    Chloroquine combined with primaquine has been the standard radical curative regimen for Plasmodium vivax and Plasmodium ovale malaria for over half a century. In an open-label crossover pharmacokinetic study, 16 healthy volunteers 4 males and 12 females aged 20 to 47 years were randomized into two groups of three sequential hospital admissions to receive a single oral dose of 30 mg base primaquine, 600 mg base chloroquine, and the two drugs together. Desethylchloroquine and bisdesethylchloroquine concentrations reach 40 and 10% of chloroquine concentrations, respectively; both chloroquine and desethylchloroquine concentrations decline slowly, with elimination half-lives of 20 to 60 days. 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.

    I don't know if I'm getting paranoid, or finally realizing that there are often connections to off the wall symptoms with lupus and AI issues. It finally subsided today, so i didn't press my luck. I have had problems with my left ear since about a year after I was diagnosed.

I too have this ear pain and never related it to Lupus, and cannot remember if the mouth sores were present at the time i have the ear pain. the side of my face will be sore to the touch, and ache, and my ear hurts, and sometimes there is sore throat. to be able to eat in peace and without pain would be wonderful. I went to the Ent on Friday and am currently waiting for Blood work to come back to see if i have it. I dont have it today but usually have it a few times a week.
