التداخل بين أتينولول وكلورثاليدون وديجوكسين

Serum potassium levels should be carefully monitored when digoxin is given to patients at high risk of hypokalemia ( e.g. , those receiving diuretics, corticosteroids, or other drugs that commonly lead to potassium loss; those with gastrointestinal losses through diarrhea, vomiting, or nasogastric suction; or those with potassium-losing endocrinopathies or nephropathies).

Beta-adrenergic Blockers and Calcium Channel Blockers Additive effects on AV node conduction can result in complete heart block.

Amiodarone is an antiarrhythmic agent with negative chronotropic properties that may be additive to those seen with beta-blockers.

Both digitalis glycosides and beta-blockers slow atrioventricular conduction and decrease heart rate.

(See WARNINGS .) Disopyramide is a Type I antiarrhythmic drug with potent negative inotropic and chronotropic effects.
