What the FDA labels say
From the Nebivolol (Bystolic) label · effective 2024-08-01
Use with CYP2D6 Inhibitors Nebivolol exposure increases with inhibition of CYP2D6 [see Drug Interactions ( 7 ) ] .
CYP2D6 Inhibitors Use caution when BYSTOLIC is co-administered with CYP2D6 inhibitors (quinidine, propafenone, fluoxetine, paroxetine, etc.) [see Clinical Pharmacology ( 12.5 )] .
Calcium Channel Blockers BYSTOLIC can exacerbate the effects of myocardial depressants or inhibitors of AV conduction, such as certain calcium antagonists (particularly of the phenylalkylamine [verapamil] and benzothiazepine [diltiazem] classes), or antiarrhythmic agents, such as disopyramide.
From the Quinidine (Quinidine Gluconate) label · effective 2024-08-27
The effects (if any) of coadministration of other β-blockers on quinidine pharmacokinetics have not been adequately studied.
Coadministration of propranolol usually does not affect quinidine pharmacokinetics, but in some studies the β-blocker appeared to cause increases in the peak serum levels of quinidine, decreases in quinidine's volume of distribution, and decreases in total quinidine clearance.
