डिल्टियाज़ेम और एस्मोलोल का इंटरैक्शन

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.

Concomitant use of diltiazem with beta-blockers or digitalis may result in additive effects on cardiac conduction.

• Beta-blockers, digitalis, and other agents known to impair cardiac contractility and conduction may increase risk for hypotension, bradycardia, and heart failure.

Experience with the use of diltiazem in combination with beta-blockers in patients with impaired ventricular function is limited.
