Knowing a drug’s potential for partitioning is critical in situations where the test drug has a high Log P (lipophilic). In this situation a significant portion of the drug may be taken up and held by red blood cells (RBCs).

This is a list of compounds that are in the BPP dataset. BPP Assay Compounds partial list Acebutolol. Acetophenetidine Chloroquine concentrations in packed red blood cells consistently exceeded those in plasma and showed no consistent change with time throughout the period of study in either group. The median value for the red cell to plasma ratio was between 3 and 4 in each group. ABSTRACT TRUNCATED AT 250 WORDS Chloroquine is rapidly and almost completely absorbed from the gastrointestinal tract, and only a small proportion of the administered dose is found in the stools. Approximately 55% of the drug inthe plasma is bound to nondiffusible plasma constituents. Excretion of Chloroquine is quite slow,but is increased by acidification of the urine. When the combined knowledge of protein binding and blood partitioning is understood investigators can make a better determination about whether they should collect whole blood, plasma, or serum for assaying pharmacokinetic behavior of the drug if animal or clinical ADME studies. For this reason, more informative data describing drug distribution in blood can be obtained by determining both the blood partitioning ratios and direct protein binding.

Prediction of human blood‐to‐plasma drug concentration ratio.. 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, the plasma clearance significantly overestimates blood clearance. Separate plasma by centrifugation. Transfer the serum, plasma or whole blood to a plastic transport tube see Pediatric Specimen Tubes below. To prevent injury and exposure to potentially infectious material, do not ship frozen serum, plasma, or whole blood received in glass tubes or SST glass or plastic. 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.
