Paroxetine significantly inhibits the metabolism of both metoprolol IR and ER, resulting in an increase in the magnitude and duration of [H9252]-blockade. The potential risk of adverse effects from excessive β-blockade may be greater with metoprolol IR than with metoprolol ER because of the significantly higher peak S-metoprolol plasma concentrations achieved with the IR formulation. Thus, if paroxetine treatment is indicated in patients receiving metoprolol, use of the ER formulation may reduce the risk of adverse effects.
