Strong inhibitor is one that causes a ≥ 5-fold decrease in the plasma AUC values or more than 80% decrease in clearance.
Moderate inhibitor is one that causes a 2 fold to < 5-fold decrease in the plasma AUC values or 50-80% decrease in clearance.
Weak inhibitor is one that causes a ≥ 1.25-fold but < 2-fold decrease in the plasma AUC values or 20-50% decrease in clearance.
