Results: During itraconazole treatment, or 4 days after, α-hydroxymetabolite the dose-corrected area under the plasma midazolam concentration–time curve (AUC 0–∞) was 8- or 2.6-fold larger than that before itraconazole (i.e. 1707 or 695 versus 277 ng · h · ml −1), respectively. Time (h) C (therapeutic ), min 250 275 300 325 C(thetapeutic max 350 — Plasma concentl ation C (mg/L) plasma concentration tüne curve Plasma concentration-time curve 0.0250 0.0"5 0.0200 0.0175 0.0150 The area under the plasma concentration-time curve for oral midazolam is 400-fold larger during treatment with itraconazole than with rifampicin. Switching from inhibition to induction of cytochrome P450 3A (CYP3A) enzymes causes a very great (400-fold) change in the AUC of oral midazolam. Area under the curve (AUC) is expressed in units of mgh/mL (mg6h/mL) AUC total area under the plasma drug concentration–time curve (from time zero to infinity). Whenever the determination of AUC is partial (incomplete), the time period over which it is determined should be specified; for example, AUC0–12h refers to area under Area under the plasma concentration time curve (AUC) The area under the plasma (serum, or blood) concentration versus time curve (AUC) has an number of important uses in toxicology, biopharmaceutics and pharmacokinetics.

Likewise, when changing infusion rates, the time required to reach the new steady state also depends on the half-life of the drug. When stopping an iv infusion, the decline in plasma drug concentration follows an exponential curve Changes in plasma concentration-time curve. The plasma concentration-time curve may be lowered or raised, or the concentration may fluctuate outside the therapeutic window. This effect depends on the pharmacokinetics of the drug in that patient.

The list of abbreviations related to AUC - Area Under plasma concentration-time Curve. The plasma concentration-time curve (blood level curve) is the focal point of bioavailability assessment and is obtain when serial blood samples are taken after drug administration and analyzed for drug concentration A typical blood level curve obtained after oral administration of a drug is as follows:- plasma levodopa concentrations produced by all six preparations are shown in Table 1. The considerable individual variation in the plasma levodopa concentrations is reflected in the large standard errors.

If we can compute area under the plasma concentration-time curve after deleting some of the data points without affecting the accuracy of the area then we will have to take less blood samples to After 4 elimination half-lives the drug plasma concentration is 93,75% of the steady state plasma concentration. Likewise, when changing infusion rates, the time required to reach the new steady state also depends on the half-life of the drug. When stopping an iv infusion, the decline in plasma drug concentration follows an exponential curve Area under the plasma concentration-time curve from zero to the time of the last quantifiable concentration AUC ex Percent of AUC obtained by extrapolation AUC ss AUMC Area under the plasma concentration-time curve during a dosing interval (tau) at steady-state Total area under the first moment-time curve dose demonstrate a plasma level-time curve that does not decline as a single exponential (first-order) process. The plasma level-time curve for a drug that follows a two-compartment model shows that the plasma drug concentration declines biexponentially as the … What is the abbreviation for Area Under plasma concentration-time Curve? What does AUC stand for? AUC abbreviation stands for Area Under plasma concentration-time Curve. under the plasma rabeprazole concentration-time curve (AUC) does not predict the acid suppressive effect of PPIs [12–14], the AUC level of rabeprazole would affect the clinical efficacy in some situations [2–6].

This is the amount of a particular medication in the blood, 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.

Because interstitial fluid chemical concentra- tion reflects its plasma concentration, the integrated concentration gradient can be approximated by the area under the plasma concen- tration-time curve (AUC) for the time period of transcutaneous collection. 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. 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). 3'1.

The curve is interpreted as follows: with chronic exposure of increasing doses up to the threshold, no effect is detectable  The area under the plasma concentration versus time curve, from time 0 to the time of the Blood donation 90 without over to the commencement of the study. 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. This area under the curve is dependant on the rate of elimination of the drug from the body and the dose administered.

If you look at the following curve, you see a rapid increase marked "absorption phase", and a gradual decrease marked "elimination phase". This is the amount of a particular medication in the blood, 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. The aim was to develop and validate limited sampling strategy (LSS) models to predict the area under the plasma concentration–time curve (AUC) for metformin. Methods. Metformin plasma concentrations (n = 627) at 0–24 h after a single 500 mg dose were used for LSS development, based on all subsets linear regression analysis.
