What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]
Time Frame: 7 days
AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).
7 days
Maximum Observed Plasma Concentration (Cmax)
Time Frame: 7 days
7 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)
Time Frame: 7 days
Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)
7 days
Apparent Oral Clearance (CL/F)
Time Frame: 7 days
Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.
7 days
Plasma Decay Half-Life (t1/2)
Time Frame: 7 days
Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
7 days
Apparent Volume of Distribution (Vz/F)
Time Frame: 7 days
Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.
7 days
