    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).

    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 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. A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen.

    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 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 I understand that the drug chloroquine has a "half-life" in the human body of 45-55 days. means that if you take a pill, the concentration of chloroquine will be at 1/2 of that level about 50 days later.

    I am wondering if anyone else in the UK has been given a hydroxychloroquine injection before starting on meds? Methotrexate or Plaquenil? DailyStrength Ask the Expert Plaquenil and Sjögren’s Plaquenil Oral Uses, Side Effects, Interactions, Pictures.

    Chloroquine and HydroxyChloroquine Toxicity ROQUE Eye. Many reports on chloroquine retinopathy exist. In contrast, only a few cases of hydroxychloroquine toxicity have been reported. Pathophysiology Chloroquine has an affinity for pigmented melanin-containing structures, which may explain its toxic properties in the eye. Melanin serves as a free-radical stabilizer and as an agent that can bind.
