Effects of Ranolazine on Other Drugs
- Drugs Metabolized by CYP2D6: Ranexa 750 mg twice daily increased the plasma concentrations of a single dose of immediate-release metoprolol (100 mg), a CYP2D6 substrate, by 1.8-fold. The exposure to other CYP2D6 substrates, such as tricyclic antidepressants and antipsychotics, may be increased during co-administration with Ranexa, and lower doses of these drugs may be required.
