Since modern drug development, drug concentration assays have almost exclusively used plasma as a matrix rather than whole blood. Various theories about assay sensitivity, matrix interference, protein binding, and free drug movement have been put forth to explain why it is “best” to measure drug concentrations in plasma. PubMed The mechanisms that determine this plasma-concentration profile ( absorption, distribution, metabolism and excretion) are characterized by pharmacokinetic parameters.

Plasma concentration formula

Maintenance dose = [desired plasma concentration at steady state] x [clearance] / [bioavaliability of the drug]. NOTE: Medications obeying first-order kinetics reach steady-state concentration in 4-5 half-lives. Additional Readings: Basic Pharmacology. 1. The Formula of Osmolarity: Osmolarity= (number of moles of dissolved particles) / (numbers of liters of solution) How to Calculate Osmolarity from Molarity? To calculate Osmolarity multiply the Molarity by the number of Osmoles that each solute produces.

By that drug concentrations in these fluids are in equilibrium with the drug concentration at the receptor. It should be noted that the measured drug concentrations in plasma or serum are often referred to as drug levels, which is the term that will be used throughout the text.
