التداخل بين بريمونيدين وتيمولول ونيكارديبين

However, titrate slowly when using CARDENE I.V. in combination with a beta-blocker in heart failure patients [see Warnings and Precautions (5.2) ].

Exacerbation of Heart Failure Titrate slowly when using CARDENE I.V., particularly in combination with a beta-blocker, in patients with heart failure or significant left ventricular dysfunction because of possible negative inotropic effects.

Beta-Blockers In most patients, CARDENE I.V. can safely be used concomitantly with beta blockers.

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.

Antihypertensives/Cardiac Glycosides Because brimonidine tartrate/timolol maleate ophthalmic solution may reduce blood pressure, caution in using drugs such as antihypertensives and/or cardiac glycosides with brimonidine tartrate/timolol maleate ophthalmic solution is advised.

Calcium Antagonists Caution should be used in the co-administration of beta-adrenergic blocking agents, such as brimonidine tartrate/timolol maleate ophthalmic solution, 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.
