Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Plasma Pharmacokinetics (PK) of Furosemide: Area Under the Plasma Concentration-time Curve (AUC)
Time Frame: pre-dose, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10 and 24 hours post dose
|
Pharmacokinetic (PK) parameters were determined from the plasma concentration time profile of furosemide using a non-compartmental method: AUCtau: Area under the plasma concentration-time curve from time zero to the end of the dosing interval AUC (0-24): Area under the plasma concentration-time curve from time zero to 24 hours AUClast: Area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration. AUClast was calculated as the sum of linear trapezoids using non-compartmental analysis. AUCinf: Area under the plasma concentration-time curve from time zero to infinity. AUCinf was calculated by adding AUClast and the value obtained from dividing the last measurable plasma concentration by λz, where λz was determined from automated linear regression of the last three time points with non-zero concentrations in the terminal phase of the log-transformed concentration-time profile |
