AUC t Amount · time/volume Area under the plasma concentration-time curve from time zero to time t Note: AUC 24, not AUC 0–24 or AUC 24h; however, if time periods >24 hours are used, these will have to be specified, e.g. if measured over 36 hours or 8 days or 3 weeks, AUC 36h, AUC 8d or AUC 3wk,respectively

Both formulations showed similar pharmacokinetic profiles. Mean (SD) AUC(last), AUC(∞) and C(max) were 1436 (341) ng · h/mL, 1595 (381) ng · h/mL and 32.3 (5.9) ng/mL, respectively, for the test formulation (AUC) of absorption of drug from a test formulation (vs.

Historically, AUC was calculated using Area under the curve (AUC) is expressed in units of μg · h/mL (μg × h/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, AUC 0–12 h refers to area under the curve from time 0 to 12 h after drug administration The present study examines the pharmacokinetics and bioavailability of sulfamonomethoxine in Japanese ell Anguilla japonica that is the most popular cultured fish in Japan. 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 AUC t Amount · time/volume Area under the plasma concentration-time curve from time zero to time t Note: AUC 24, not AUC 0–24 or AUC 24h; however, if time periods >24 hours are used, these will have to be specified, e.g.

Single IV doses (25–600 mg) increased the AUC 0–24 from 0.9 to 24.9 µg × hour/mL in a dose-dependent manner. Over the same dose range, C max ranged from 0.3 to 4.5 µg/mL. Pharmacokinetics (PK) is the analysis and description of the disposition of a drug in the body, encompassing development of the mathematical description of all dispositional processes in the body, defined as ADME – absorption, distribution, metabolism, and elimination.

the pharmacokinetics can be adequately described. This is chosen by the kineticist and statistician jointly Following loge-transformation, dose normalised AUC and Cmax will be analysed using a mixed model appropriate to the study design. Each dose will be compared with the reference dose on a pairwise basis.

AUC t Amount · time/volume Area under the plasma concentration-time curve from time zero to time t Note: AUC 24, not AUC 0–24 or AUC 24h; however, if time periods >24 hours are used, these will have to be specified, e.g. if measured over 36 hours or 8 days or 3 weeks, AUC 36h, AUC 8d or AUC 3wk,respectively The "area under the curve," or AUC, is calculated by adding up the area under the curved line that charts the peak and trough levels of a drug.
