WebHuman Model. Plasma concentration (Cp) is directly proportional to the dose rate, and inversely proportional to the clearance (CL). i.e. Cp = Dose rate/CL. The steady state concentration (Cpss) is thus determined by the maintenance dose rate and the clearance. Adjust the dose rate and the clearance to see what happens to the plasma concentration. Drug elimination is usually divided into two major components: excretion and biotransformation. Drug excretion is the removal of the intact drug. Nonvolatile drugs are excreted mainly by renal excretion, a process in which the drug passes through the kidney to the bladder and ultimately into the urine. … See more Drugs are removed from the body by various elimination processes. Drug elimination refers to the irreversible removal of drug from the body by all routes of elimination. … See more Drug elimination in the body involves many complex rate processes. Although organ systems have specific functions, the tissues within the … See more The advantage of the clearance approach is that clearance applies to all elimination rate processes, regardless of the mechanism for elimination. In addition, for first-order elimination processes, clearance is a … See more
