Interactions between your drugs
timolol ophthalmic rizatriptan
Applies to: Timoptic-XE (timolol ophthalmic), rizatriptan
Coadministration with rizatriptan may alter the plasma concentrations of drugs that are primarily metabolized by CYP450 2D6. Rizatriptan has been shown to be a competitive inhibitor of CYP450 2D6 in vitro, but only at high, clinically irrelevant concentrations and a clinically significant inhibitory effect on CYP450 2D6 has not been demonstrated in clinical drug interaction studies. Based on these observations, rizatriptan may be administered with CYP450 2D6 substrates without the need for increased clinical monitoring
