More information
- Bupropion slows the metabolism of amitriptyline via CYP2D6.
-
- Due to CYP inhibition a longer period of time is needed to reach steady state concentration. Please keep in mind when monitoring plasma levels
- The concomitant use of bupropion and tricyclic antidepressants (TCAs) may potentiate the risk of seizures. These agents are all epileptogenic and may have additive effects on the seizure threshold.
