Amiodarone · more major-labeled pairs than Carvedilol
SPL labels Amiodarone + Carvedilol as minor; Amiodarone 29 / Carvedilol 12 in that band.
Mechanism on file: Amiodarone blocks the proteins that normally break down carvedilol, which can cause carvedilol to build up and slow your heart rate too much.
FDA SPL severity: Minor

Amiodarone blocks the proteins that normally break down carvedilol, which can cause carvedilol to build up and slow your heart rate too much.
Minor band excerpt · Amiodarone with Carvedilol
( 7.4 ) Amiodarone may increase carvedilol levels resulting in further slowing of the heart rate or cardiac conduction. 7.6 Amiodarone Amiodarone and its metabolite desethyl amiodarone, inhibitors of CYP2C9, and P-glycoprotein increased concentrations of the S(-)-enantiomer of carvedilol by at least 2 fold [see Clinical Pharmacology ( 12.5 )] . The concomitant administration of amiodarone or other CYP2C9 inhibitors such as fluconazole with carvedilol may enhance the β-blocking activity, resulting in further slowing of the heart rate or cardiac conduction.
