This is the first in a series of five models used to illustrate different types of pharmacokinetic-based drug-drug interactions (DDI). The model demonstrates the characteristics of time dependent inhibition (TDI) or mechanism based enzyme inhibition. It demonstrates how the inhibitor’s potency parameter, KI (concentration that results in half-maximal inhibition) and the inhibitor’s parameter representing its destructive power, kinact (the maximal rate constant of inactivation) impact the extent of inhibition. It also demonstrates the relationship between kobs and kinact . Finally the model shows how the enzyme’s degradation rate constant controls recovery from a TDI.
