The plasma concentration time-curve represents distribution phase (α) followed by an elimination phase (β) after the tissue compartment has also been diffused with the drug. ADVERTISEMENTS: The distribution phase may take minutes and may be missed entirely if the blood is sampled too late after administration of the drug.

In nonfasting healthy human subjects (males and females), peak plasma concentrations were attained within 2 to 3 hours after oral dosing.

Scanned plots of the published plasma concentrations vs. time curves were used to obtain the plasma concentration data points and to calculate the AUC(0,24 h) best estimates, by means AUC is defined as plasma concentration-time curve from time zero to time infinity rarely. AUC stands for plasma concentration-time curve from time zero to time infinity. Printer friendly.

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. 2017-04-11 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). 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.

Pharmacodynamic parameters. A typical plasma drug concentration-time curve obtained after a single oral dose of a drug and showing various pharmacokinetic.

This figure appears on page 51 of Pharmacology in Clinical Practice 3rd edition.The plasma concentration-time curve in this figure illustrates the pharmacoki Figure 7 shows the mean plasma concentration-time curves for buprenorphine obtained from six patients after receiving, in two different sessions approximately 7 days apart: buprenorphine 8 g/L in 1 mL of 300 mL/L ethanol, held sublingually for 5 min; and a prototype buprenorphine 8-mg tablet, also held sublingually for 5 min. From Wikipedia, the free encyclopedia 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).

Where , C− = back extrapolated plasma concentration values φ A plot of log C versus t yield a biexponential curve with a terminal linear phase having slope –KE/2.303 φ Back extrapolation of this straight line to time zero yields y-intercept equal to log A. 70

Time Curve. If you look at the following curve, you see a rapid increase marked "absorption phase", and a gradual decrease marked "elimination phase".

Time Data Using PROC SGPLOT, continued 4 Figures A Mean Plasma Concentration vs. Time curve of Drug A (n = 3) Figure 1: Linear Plot of Mean Plasma Concentrations versus Time Curves of Drug A to healthy, adult, male human subjects under fasting condition. The maximum plasma concentration ([C.sub.max]) for digoxin was obtained by visual inspection of the plasma concentration-time curve, whereas the initial drug concentration (the extrapolated concentration at zero time) of the drug after intravenous injection was calculated by back-extrapolation of the plasma concentration-time curve to the y-axis.

Note that in steady state and in linear pharmacokinetics AUCτ=AUC∞. Steady state is reached after about 5 × 12 = 60 hours. The graph depicts a typical time course of drug plasma concentration and illustrates main pharmacokinetic metrics centration of drug in plasma increases, the concentration of drug in most tissues will increase proportionally.
