डिल्टियाज़ेम और डोरज़ोलामाइड और टिमोलोल का इंटरैक्शन

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.

Oral or intravenous calcium antagonists may cause atrioventricular conduction disturbances, left ventricular failure, and hypotension.

Digitalis and calcium antagonists may have additive effects in prolonging atrioventricular conduction time.

Calcium Antagonists Caution should be used in the coadministration of beta-adrenergic blocking agents, such as COSOPT PF, and oral or intravenous calcium antagonists because of possible atrioventricular conduction disturbances, left ventricular failure, and hypotension.

Digitalis and Calcium Antagonists The concomitant use of beta-adrenergic blocking agents with digitalis and calcium antagonists may have additive effects in prolonging atrioventricular conduction time.
