التداخل بين كلونيدين وبروبرانولول

Abrupt discontinuation of QLONILIK can cause rebound hypertension with elevated plasma catecholamines, especially with higher doses or concomitant beta-blocker use.

Rebound Hypertension Abrupt discontinuation of QLONILIK can cause rebound hypertension with elevated plasma catecholamines, especially with higher doses or concomitant beta-blocker use.

Drugs that affect sinus node function or AV node conduction (e.g., digitalis, calcium channel blockers, beta blockers) Clinical Implication Concomitant use of drugs that affect sinus node function or AV node conduction with clonidine potentiate bradycardia and risk of AV block [see Warnings and Precautions (5.1) ].

When discontinuing concurrent beta-blocker therapy, withdraw the beta-blocker several days before beginning clonidine taper.

The concomitant use of beta-adrenergic blockers and non-dihydropyridine calcium channel blockers (e.g., verapamil and diltiazem), digoxin or clonidine increases the risk of significant bradycardia.

Pharmacodynamic Drug-Drug Interactions Adrenergic Agonists: Beta-blockers may antagonize the antihypertensive effects of clonidine, and rebound hypertension may result if clonidine is withdrawn abruptly.

If clonidine and a beta-blocker are co-administered, withdraw the beta-blocker several days before the withdrawal of clonidine.
