Fluoxetine cyp2d6 inhibition

Fluoxetine inhibits the activity of the cytochrome p450 isoenzyme system of cyp2d6 and thus changes the normal metabolic activity of the isoenzyme to a level similar to that of slow metabolizers. Inhibition of cyp2d6 activity in patients undergoing treatment with fluoxetine or other serotonin uptake inhibitors could contribute to toxicity or attenuated response from concurrent medications that.
