In Vitro Enzyme Inhibition Experiment

No inhibition of CYP3A4 by mitragynine

Negligible 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.
