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.

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].

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.

PK parameters of imatinib, derived from the plasma concentration–time curves, were The shape of the Cp/time curves is defined by pharmacokinetic factors. The relationship between dose and plasma concentration is linear.

The intraindividual variability of the area under the concentration-time curves (AUC0-12) of MPA throughout the 12-hour dosing interval was high in the immediate posttransplant period, but declined in the stable phase, whereas the interindividual variability remained unchanged.

The area under the plasma (serum, or blood) concentration versus time curve (AUC) has an number of important uses in toxicology, biopharmaceutics and pharmacokinetics. Toxicology AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure how much - how long a drug stays in a body.

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.

Similarly, areas under the plasma concentration-time curve (0-8 h) were not different in those reporting sedation from those who did not after oral (363 [+ or -] 169, vs. The association of age and frailty with the pharmacokinetics and pharmacodynamics of metoclopramide

Bioequivalence of Two Levonorgestrel/Ethinyl Estradiol Formulations.

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.
