WebThe time delay prior to the commencement of first-order drug absorption is known as lag time. The lag time for a drug may be observed if the two residual lines obtained by feathering the oral absorption plasma level time curve intersect at a point greater than t = 0 on the x axis. The time at the point of intersection on the x axis is the lag time. WebPharmacokinetic–pharmacodynamic modeling Roflumilast pharmacokinetics have been studied using a two-compartment model with first-order absorption and a lag time [34 C]. A one-compartment model with zero-order absorption was used for roflumilast N-oxide.
