Clearance is especially important for insuring appropriate long-term drug dosing -- correct steady-state drug concentrations in Basic and Clinical Pharmacology
Clearance relates the rate of elimination to the concentration measured in the body. Clearance is a function of organ function, and efficiency and is different for each drug. Many physiological changes are associated with obesity and can potentially impact on pharmacokinetics.
The quantity reflects the rate of drug elimination divided by plasma concentration. clearance Pharmacology The elimination of a drug, therapeutic agent, or other substance from the body or other biologic system; clearance is expressed as a hypothetical volume that is completely removed in a given unit of time; in terms of pharmacokinetics, clearance is the product of the volume of distribution and the elimination rate constant; much of a drug's elimination is via the kidneys and clearance is commonly expressed in mL/min or L/hr. Clearance: the drug's rate of elimination (by all routes) normalized to the concentration of drug C in some biological fluid: CL = Rate of elimination / C Clearance (pharmacology) clearance cleared elimination metabolic clearance rate renal clearance renal excretion clear drug clearance eliminated plasma clearance In pharmacology, clearance is a pharmacokinetic measurement of the volume of plasma from which a substance is completely removed per unit time. wikipedia Clearance is another index of the ability of the body to eliminate drug.
Thus plasma drug concentrations are determined by the rate at which drug is administered, its clearance, and V d. Clearance: the drug's rate of elimination (by all routes) normalized to the concentration of drug C in some biological fluid: CL = Rate of elimination / C http://usmlefasttrack.com/?p=5021 Clearance, (CL), -, Pharmacology, , Findings, symptoms, findings, causes, mnemonics, review, what is, video, study, Rapid General Principles of Drug Therapy Marc Imhotep Cray, M.D. Drug Clearance (Cl) 33 Drug clearance (from plasma) is defined as: volume of plasma cleared of drug per unit time; or A constant relating rate of elimination to plasma concentration (Cp) i.e. rate of elimination = Cl * Cp Units: vol/time (e.g. L/h) 34. Clearance (pharmacology) clearance cleared elimination metabolic clearance rate renal clearance renal excretion clear drug clearance eliminated plasma clearance In pharmacology, clearance is a pharmacokinetic measurement of the volume of plasma from which a substance is completely removed per unit time. wikipedia In pharmacology, clearance is a pharmacokinetic measurement of the volume of plasma from which a substance is completely removed per unit time.

Clearance (Pharmakologie) - Clearance (pharmacology) Aus Wikipedia, der freien Enzyklopädie In der Pharmakologie ist die Clearance eine pharmakokinetische Messung des Plasmavolumens, aus dem eine Substanz pro Zeiteinheit vollständig entfernt wird.
Augmented renal clearance is associated with suboptimal exposure to critical medications, including β‐lactams and vancomycin, increasing the risk of treatment failure. Although definitive screening tools are not yet known, critical care pharmacists must be vigilant in recognizing when ARC may be a contributing factor affecting expected treatment outcomes in individual patients.
Usually, clearance is measured in L/h or mL/min. The quantity reflects the rate of drug elimination divided by plasma concentration. In pharmacology, clearance is a pharmacokinetic measurement of the volume of plasma from which a substance is completely removed per unit time. Usually, clearance is measured in L/h or mL/min. The quantity reflects the rate of drug elimination divided by plasma concentration.
Renal excretion of the drug is the neat result of glomerular filtration, active tubular secretion and tubular reabsorption. Rare drugs may undergo renal metabolism (e.g.

If clearance is altered in a drug interaction, the steady state concentration will change. An enzyme inducer will increase the clearance, by providing more enzyme. Drug concentrations will decrease.

Clearance is related with volume of distribution as Drug clearance from the body is the result of elimination by renal excretion and by extrarenal pathways (no renal clearance), usually by liver metabolism. The unbound moiety of the drug can be eliminated, so an increase in the plasma level of free drug, commonly observed in critically ill patients, may significantly reduce the clearance mainly for highly protein-bound antibiotics, such as ceftriaxone. clearance Pharmacology The elimination of a drug, therapeutic agent, or other substance from the body or other biologic system; clearance is expressed as a hypothetical volume that is completely removed in a given unit of time; in terms of pharmacokinetics, clearance is the product of the volume of distribution and the elimination rate constant; much of a drug's elimination is via the kidneys and clearance is commonly expressed in mL/min or L/hr. Clearance represents the capacity for drug removal by various organs and is defined as the volume of blood from which all drug is removed per minute (mL/minute). Both clearance and distribution volume are model-independent parameters.
