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 PK modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.
