Apparent Oral Clearance (CL/F)
Zeitfenster: 0-48 hours post-final dose on Day 14
|
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.
Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.
|
0-48 hours post-final dose on Day 14
|
|
Apparent Volume of Distribution (Vz/F)
Zeitfenster: 0-48 hours post-final dose on Day 14
|
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.
|
0-48 hours post-final dose on Day 14
|
|
Plasma Decay Half-Life (t1/2)
Zeitfenster: 0-48 hours post-final dose on Day 14
|
Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

0-48 hours post-final dose on Day 14
|
|
