6 Dec 2017 This study compared the pharmacokinetics and bioavailability of oral and area under the plasma concentration-time curve over the dosing Pharmacokinetics Simulation. Search for a drug to visualize the plasma concentration versus time curves are generated based on a physiologically- based 21 Sep 2016 Patients received imatinib orally once or twice daily. 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. This implies that if the AUCINF_D. AUCINF divided by the administered dose. AUClast.

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. 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.

The area under the blood (or plasma) concentration –time curve reflects the amount of a xenobiotic that has effectively reached the Alternatives are sug gested which reduce peak plasma Adriamycin concentration while antitumor area under the concentration-time curve is main tained. Pharmacokinetics may be defined as what the body does to a drug.

For each dosage regimen the following parameters should be known as well: – Area under the plasma concentration time curve.

Toxicology AUC can be used as a measure of drug exposure.
