Can you take plaquenil with antibiotics Is plaquenil considered a steroid How often is plaquenil taken in the population Chloroquine has similar pharmacokinetics to hydroxychloroquine. After identical doses, the tissue levels of chloroquine are 2.5 times those seen with hydroxychloroquine. Chloroquine is rapidly and almost completely absorbed from the bowel following oral administration. Professional guide for Chloroquine. Includes pharmacology, pharmacokinetics, contraindications, interactions, adverse reactions and more. Oct 20, 2012 Chloroquine is extensively distributed with an enormous total apparent volume of distribution Vd more than 100 L/kg, and a terminal elimination half-life of 1 to 2 months. As a consequence, distribution rather than elimination processes determine the blood concentration profile of chloroquine in patients with acute malaria. For all uses of chloroquine: WARNING/CAUTION: Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug. Do not start, stop, or change the dose of any drug without checking with your doctor.

Chloroquine Pharmacology & Usage Details Medicine India. Pharmacology Pharmacokinetics. 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 Chloroquine is deposited in the tissues in considerable amounts. In animals, from 200 to 700 times the plasma concentration may be found in the liver,spleen, kidney, and lung; leukocytes also concentrate the drug. The brain and spinal cord, in contrast, contain only 10 to 30 times the amount present in plasma. The pharmacokinetics of hydroxychloroquine were found to be enantioselective. The concentrations of −‐R‐hydroxychloroquine were higher than those of the +‐S‐antipode in all patients at all time points, although the ratios of the two enantiomers did display a two to three fold variability between patients.
