एटेनोलोल और क्लोरथैलिडोन और निकार्डिपिन का इंटरैक्शन

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.

Because of its relative beta 1 -selectivity, however, atenolol and chlorthalidone may be used with caution in patients with bronchospastic disease who do not respond to or cannot tolerate, other antihypertensive treatment.

Drug Interactions Atenolol and chlorthalidone may potentiate the action of other antihypertensive agents used concomitantly.

Calcium channel blockers may also have an additive effect when given with atenolol and chlorthalidone.

Concomitant Use of Calcium Channel Blockers Bradycardia and heart block can occur and the left ventricular end diastolic pressure can rise when beta- blockers are administered with verapamil or diltiazem.
