मेटोप्रोलोल और प्रोपाफेनोन का इंटरैक्शन

CYP2D6 Inhibitors Monitor patients closely when the combination use of CYP2D6 inhibitor and metoprolol cannot be avoided.

CYP2D6 Inhibitors are likely to increase metoprolol concentration.

Drugs that are strong inhibitors of CYP2D6 such as quinidine, fluoxetine, paroxetine, and propafenone were shown to double metoprolol concentrations.

In 4 patients, administration of metoprolol with propafenone increased the metoprolol plasma concentrations at steady state by 100% to 400%.

In clinical trials using propafenone immediate-release tablets, patients who were receiving beta-blockers concurrently did not experience an increased incidence of side effects.

The pharmacokinetics of propafenone was not affected by the coadministration of either propranolol or metoprolol.
