What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Maximum Plasma Concentration (Cmax)
Time Frame: plasma samples were obtained from blood drawn at 0 (within 60 minutes prior to dose), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 20 and 24 hours (18 samples) after administration of the dose.
The maximum or peak concentration that the drug reaches in the plasma
plasma samples were obtained from blood drawn at 0 (within 60 minutes prior to dose), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 20 and 24 hours (18 samples) after administration of the dose.
Area Under the Concentration Versus Time Curve From Time 0 to Time t [AUC(0-t)]
Time Frame: plasma samples were obtained from blood drawn at 0 (within 60 minutes prior to dose), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 20 and 24 hours (18 samples) after administration of the dose.
The area under the plasma concentration versus time curve, from time 0 to the time of the last measurable concentration (t)
plasma samples were obtained from blood drawn at 0 (within 60 minutes prior to dose), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 20 and 24 hours (18 samples) after administration of the dose.
The Area Under the Plasma Concentration Versus Time Curve From Time 0 to Infinity AUC(0-∞)
Time Frame: plasma samples were obtained from blood drawn at 0 (within 60 minutes prior to dose), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 20 and 24 hours (18 samples) after administration of the dose.
The area under the plasma concentration versus time curve from time 0 to infinity. AUC(0-∞) was calculated as the sum of AUC(0-t) plus the ratio of the last measurable plasma concentration to the elimination rate constant.
plasma samples were obtained from blood drawn at 0 (within 60 minutes prior to dose), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 20 and 24 hours (18 samples) after administration of the dose.
