In Vitro Enzyme Inhibition Experiment
Inhibition of CYP2D6 by mitragynine
Inhibition was detected. Cutoff used — High probability of interaction if their IC50 values are less than 1 µM. If IC50 values are between 1 and 10 µM, they have moderate possibility in interaction. Low drug-drug interactions if their IC50 values are greater than 10 µM.
