Esmolol ve Verapamil etkileşimi

IV administration of cardiodepressant calcium-channel antagonists (e.g., verapamil) and BREVIBLOC in close proximity (i.e., while cardiac effects from the other are still present); fatal cardiac arrests have occurred in patients receiving BREVIBLOC and intravenous verapamil.

Coadministration of IV cardiodepressant calcium-channel antagonists (e.g. verapamil) in close proximity to BREVIBLOC injection (4, 7)

Antihypertensive agents clonidine, guanfacine, or moxonidine: Beta blockers also increase the risk of clonidine-, guanfacine-, or moxonidine-withdrawal rebound hypertension.

Antihypertensive agents: Risk of rebound hypertension (7)

If, during concomitant use of a beta blocker, antihypertensive therapy needs to be interrupted or discontinued, discontinue the beta blocker first, and the discontinuation should be gradual.

Beta blockers: reports of excess bradycardia and AV block, including complete heart block; monitor closely ( 7.4 )

Beta Blockers Concomitant therapy with beta-adrenergic blockers and verapamil may result in additive negative effects on heart rate, atrioventricular conduction, and/or cardiac contractility.

Antihypertensive Agents Verapamil administered concomitantly with oral antihypertensive agents (e.g., vasodilators, angiotensin-converting enzyme inhibitors, diuretics, beta blockers) will usually have an additive effect on lowering blood pressure.

Avoid verapamil in patients with severe left ventricular dysfunction (e.g., ejection fraction less than 30% or moderate to severe symptoms of cardiac failure) and in patients with any degree of ventricular dysfunction if they are receiving a beta-adrenergic blocker [see Drug Interactions ( 7.4 )].

The combination of extended-release verapamil and beta-adrenergic blocking agents has not been studied.
