प्रोपाफेनोन और प्रोप्रानोलोल का इंटरैक्शन

Propafenone: Co-administration of propranolol increases the plasma concentrations of propafenone.

Monitor patients for symptoms of excessive exposure to propafenone including bradycardia and postural hypotension [see Clinical Pharmacology ( 12.7 )] .

Impact of Other Drugs on Propranolol CYP2D6, CYP1A2 and CYP2C19 Inhibitors: CYP2D6 inhibitors (e.g. bupropion, fluoxetine, paroxetine, quinidine), CYP1A2 inhibitors (e.g., ciprofloxacin, enoxamine, fluvoxamine) and CYP2C19 inhibitors (e.g., fluconazole, fluvoxamine, ticlopidine) increase exposure to propranolol when co-administered with INNOPRAN XL.

Beta-Antagonists Concomitant use of propafenone and propranolol in healthy subjects increased propranolol plasma concentrations at steady state by 113%.

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.
