التداخل بين كلونيدين وميتوبرولول وهيدروكلوروثيازيد

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.

Digitalis, Clonidine, and Calcium Channel Blockers: Digitalis glycosides, clonidine, diltiazem and verapamil slow atrioventricular conduction and decrease heart rate.

Digitalis glycosides, clonidine, diltiazem and verapamil: Bradycardia.

Clonidine: Rebound hypertension following clonidine withdrawal.

If clonidine and a beta blocker, such as metoprolol are coadministered, withdraw the beta- blocker several days before the gradual withdrawal of clonidine because beta-blockers may exacerbate the rebound hypertension that can follow the withdrawal of clonidine.

If replacing clonidine by beta-blocker therapy, delay the introduction of beta-blockers for several days after clonidine administration has stopped.
