    The presences of diethyl diamino pentane as a side chain is optimum for activity as in chloroquine OH group addition in side chain at ethyl group the Hydroxy chloroquine, which is less toxic and produce the high blood levels but slightly lowers the activity Hydroxychloroquine has similar pharmacokinetics to chloroquine, with rapid gastrointestinal absorption and elimination by the kidneys. Cytochrome P450 enzymes CYP2D6, 2C8, 3A4 and 3A5 metabolize hydroxychloroquine to N-desethylhydroxychloroquine. Pharmacodynamics. Antimalarials are lipophilic weak bases and easily pass plasma membranes. Hydroxychloroquine HCQ and chloroquine CQ are well absorbed 0.7-0.8 bioavailability when given orally. Severe malnutrition such as kwashiorkor effects absorption but diahrrea does not. Both HCQ and CQ have prolonged half-lives, between 40 and 50 days, and low blood clearance e.g. hydroxychloroquine's blood clearance is 96 ml/min.

    The absorption, distribution and elimination of chloroquine were studied in rabbits upon oral administration of chloroquine with aspirin. 2. The time-lag, half-life of absorption and absorption rate constant obtained in both cases were significantly different P 0.01 whereas the half-life of elimination and the elimination rate constant. The ability of activated charcoal to prevent the absorption of chloroquine was investigated in healthy volunteers, and the effect of the charcoal-chloroquine ratio on the completeness of binding was studied in vitro.2 After an overnight fast, six subjects ingested 500 mg of chloroquine phosphate with water, and another group of six subjects ingested 25 g of charcoal suspension within 5 min. Apr 02, 2019 Antacids and kaolin Antacids and kaolin can reduce absorption of chloroquine; an interval of at least 4 hours between intake of these agents and chloroquine should be observed. Cimetidine. Cimetidine can inhibit the metabolism of chloroquine, increasing its plasma level. Concomitant use of cimetidine should be avoided. Ampicillin

    a dormant stage [hypnozoites] can persist in the liver and cause relapses by invading the bloodstream weeks, or even years later.) After this initial replication in the liver (exo-erythrocytic schizogony ), the parasites undergo asexual multiplication in the erythrocytes (erythrocytic schizogony ).
