TERMS AND UNITS Unit of drug concentration: μg/mL or ng/mL. C p plasma drug concentration at any time t 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 and could exceed hepatic blood flow. Overview. Pharmacokinetics describes how the body affects a specific xenobiotic/chemical after administration through the mechanisms of absorption and distribution, as well as the metabolic changes of the substance in the body (e.g.

We previously used their approach to estimate the steady-state infusion rate to maintain 50% twitch depression (IR 50) with vecuronium.

A dose in mass units, maybe in mg. To calculate Cp 0 we need to know the volume that the drug is distributed into. But if you know the plasma concentration and the rate at which the material is appearing in the urine, you can always calculate its urinary or external ‘Clearance‘: Urine removal rate = plasma concentration times ‘clearance’. We Need To Formalize the Equation. If you cannot say it in words, you do not understand the idea.

Fresh Frozen Plasma. FFP contains 250 mL of plasma and 500 mg of fibrinogen in a citrate anticoagulant.

The elimination is proportional to the drug concentration.” Description. Zero-order elimination kinetics : The plasma concentration – time profile during the elimination phase is linear (Fig. 1). intervals (or continuously infused) to achieve a target steady-state plasma concentration. When drugs are administered at an interval that greatly exceeds their elimination half-life, large fluctuations in the plasma concentration, above and below the steady-state target concentration, will be achieved.
