    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).

    In contrast to quinine which has a relatively limited apparent volume of distribution approximately 2.51/kg in healthy adults and short elimination half-life 11 hours in healthy subjects, 16 hours in cerebral malaria, chloroquine has an enormous total apparent volume of distribution 100–10001/kg and a terminal elimination half-life of approximately one month White et al. 1985. The pharmacokinetic properties of chloroquine are complex; distribution rather than elimination processes. Half-life time of this drug is approximately 18 hours in vivo due to the degradation by the liver, but the stability of chloroquine in vitro experiments is expected to be longer. 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.

    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.

    A metabolite of chloroquine – hydroxychloroquine – has a long half-life 32–56 days in blood and a large volume of distribution 580–815 L/kg. The therapeutic, toxic and lethal ranges are usually considered to be 0.03 to 15 mg/l, 3.0 to 26 mg/l and 20 to 104 mg/l, respectively. An analog of chloroquine – hydroxychloroquine – has a long half-life 32–56 days in blood and a large volume of distribution 580–815 L/kg. The therapeutic, toxic and lethal ranges are usually considered to be 0.03 to 15 mg/l, 3.0 to 26 mg/l and 20 to 104 mg/l, respectively. The half-life of a drug is an estimate of the period of time that it takes for the concentration or amount in the body of that drug to be reduced by exactly one half 50%. The symbol for half-life is T½.
