In this video Plasma level time profile curve is explained briefly. plasma drug concentration versus time curve for a one-compartment model after an intravenous dose. 2 Concepts in Clinical Pharmacokinetics The property of kinetic There was a significant correlation between level of CYP2E1 mRNA in mononuclear cells and the area under the plasma concentration-time curve of plasma inorganic fluoride from the beginning of sevoflurane administration to infinity in uninduced and uninhibited patients (r2 = 0.56; P < 0.01). This figure appears on page 51 of Pharmacology in Clinical Practice 3rd edition.The plasma concentration-time curve in this figure illustrates the pharmacoki Areas under the plasma concentration-time curves for vitamins C and E alone or with Aloe gel (AVG) or Aloe whole leaf extract (AVL) Supplement Area under the curve ([micro]M h) Vitamin C (500 mg) 339 [+ or -] 124 Vitamin C + AVL 272 [+ or -] 144 Vitamin C + AVG 1031 [+ or -] 513 Vitamin E (420mg) 19.3 [+ or -] 23.2 Vitamin E + AVL 38.3 [+ or onset of formation of the antimicrobially active metabolite, 14-OH clarithromycin or its peak plasma concentration but does slightly decrease the extent of metabolite formation, indicated by an 11% decrease in area under the plasma concentration-time curve (AUC).

Plasma concentration time curve

The area under the blood (or plasma) concentration–time curve reflects the amount of a xenobiotic that has effectively reached the systemic circulation and as such is influenced both by the degree of bioavailability and by the rate at which a xenobiotic is removed from the body. The area under the blood (or plasma) concentration–time curve reflects the amount of a xenobiotic that has effectively reached the systemic circulation and as such is influenced both by the degree of bioavailability and by the rate at which a xenobiotic is removed from the body. In the field of pharmacokinetics, the area under the curve (AUC) is the definite integral of a curve that describes the variation of a drug concentration in blood plasma as a function of time (this can be done using liquid chromatography–mass spectrometry). Description The area under the plasma drug concentration-time curve (AUC) reflects the actual body exposure to drug after administration of a dose of the drug and is expressed in mg*h/L.

Extravascular Administration Anas Bahnassi PhD RPhOne compartment Model 2. LECTURE’S OBJECTIVES• Upon completion of this lecture, the student will able to:• Calculate plasma drug concentration at any given time after the administration of an extravascular dose of a drug, based on known or estimated pharmacokinetic parame Background: The Plasma Concentration vs. Time Curve. If you look at the following curve, you see a rapid increase marked "absorption phase", and a gradual decrease marked "elimination phase".
