What researchers measure

Primary outcomes

  1. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

    Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

    Time frame: 48 hours

  2. Maximum Observed Plasma Concentration (Cmax)

    Maximum Observed Plasma Concentration

    Time frame: 48 hours

Secondary outcomes

  1. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

    Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

    Time frame: 48 hours

  2. Time to Reach Maximum Observed Plasma Concentration (Tmax)

    Time to Reach Maximum Observed Plasma Concentration

    Time frame: 48 hours

  3. Plasma Decay Half-Life (t1/2)

    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

    Time frame: 48 hours

  4. Apparent Oral Clearance (CL/F)

    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.

    Time frame: 48 hours

  5. Apparent Volume of Distribution (Vz/F)

    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.

    Time frame: 48 hours
