    Chloroquine blood plasma ratio


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    Stability of chloroquine and desethylchloroquine in whole blood, plasma and DBS was investigated by exposing the samples to five freeze and thaw cycles. The samples were frozen at -80°C for 24 h for the first freeze cycle and 12–24 h for the following freezing cycles and thawed at room temperature for 2–3 h. Our upper and lower plasma concentrations, 2 μM and 0.3 μM, respectively, were based on the assumption that a 10- to 30-fold greater brain concentration exists when compared to plasma concentrations for CQ.49, 50 We used the average of this range, a 20-fold lower plasma concentration compared with the reported range of inhibitory concentration of 6-40 μM.17, 48 While not being able to directly verify human fetal brain concentrations, our range of predicted peak plasma concentrations 0.1. Readout Blood-to-Plasma ratio % Controls Verapamil. Assay Description Fresh blood EDTA-K2 is incubated in a humidified atmosphere of 5% CO 2 at 37 °C. 1 mL blood is removed into a 1.5 mL tube and centrifuged. A stock solution of the test compound and verapamil working solution with DMSO are spiked into 4 mL blood, respectively, and vortexed gently.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

  7. The packed cell volume PVC of the test blood is determined. Once the blood-drug dilutions are made the samples are incubated for 24 hours at 37°C. After incubation, plasma and RBCs are separated by centrifugation of whole blood samples at 1200 rpm for 10 minutes.

    The blood to plasma ratio determines the concentration of the drug in whole blood compared to plasma and provides an indication of drug binding to erythrocytes. At blood to plasma ratios of greater than 1 usually as a consequence of the drug distributing into the erythrocyte. Oct 01, 2018 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. Chloroquine and desethylchloroquine accumulate in erythrocyte cells giving higher concentrations in whole blood compared with plasma 17,18,55. Therefore, the concentration range and ULOQ values were lower in the plasma method compared with the whole blood or DBS methods.
