The plasma concentration-time curves of lumefantrine on linear (Figure) and log scale were used to calculate the variety of pharmacokinetic parameters (Table) 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). Results: During itraconazole treatment, or 4 days after, alpha-hydroxymetabolite the dose-corrected area under the plasma midazolam concentration time curve (AUC0-infinity) was 8- or 2.6-fold larger than that before itraconazole (i.e. 1707 or 695 versus 277 ng x h x ml(-1)), respectively. One day after rifampicin treatment, the AUC0-infinity of concentration but does slightly decrease the extent of metabolite formation, indicated by an 11% decrease in area under the plasma concentration-time curve (AUC).

Switching from inhibition to induction of cytochrome P450 3A (CYP3A) enzymes causes a very great (400-fold) change in the AUC of oral midazolam. 3'1. Journal of Pure and Applied Sciences Vol. 22 No.1 June 2003 pp 49-60 ISSN 0255-3643 Computation of Area Under Plasma Concentration Time Curve … The median MPA-AUC0-12 values increased 2-fold from 32.4 (range, 13.9 to 57.0) mg x h/L at 3 weeks to 65.1 (range, 32.6 to 114) mg x h/L at 3 months after transplantation, whereas the median AUC0-12 values of free MPA did not significantly change over time. The extrapolated plasma concentration at time 0, C(0), is back-extrapolated from the slope of the elimination phase of the semilogarithmic plasma concentration vs. time decay curve (see figure in Distribution and elimination phases). C(0) corresponds to the plasma concentration at time 0, if the distribution of the injected drug had been immediate. The area under the plasma (serum, or blood) concentration versus time curve (AUC) has an number of important uses in toxicology, biopharmaceutics and pharmacokinetics.

Area under the plasma concentration time curve. (AUC),. – Maximum concentration (Cmax),. – Minimum concentration (Cmin) after repeated dosing, and.

Purpose: The target area under the plasma-concentration-versus-time curve (AUC)-based dosing of carboplatin using Calvert's formula is expected to result in more acceptable toxicity and greater efficacy in elderly patients with small-cell lung cancer (SCLC) than the body surface area-based dosing strategy. 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). 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. “Integral of the plasma drug concentration-time curve” Description.

The concordance statistic (c-statistic) or area under a ROC curve (AUC) of the Studies had to report the incidence of AKI based on serum creatinine levels at 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. 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. This area under the curve is dependant on the rate of elimination of the drug from the body and the dose administered.
