Sintesi

Both lower heart rate and blood pressure, and the combination can cause significant bradycardia and hypotension. If clonidine is stopped while a beta blocker continues, rebound hypertension can be exaggerated because unopposed alpha stimulation occurs.

Cosa significa questa interazione in parole semplici

Atenolol and Clonidine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Atenolol belongs to Cardiovascular; Clonidine belongs to Cardiovascular.

Livello di evidenza: High

Perché avviene

Additive sympatholytic effects (central alpha-2 agonism plus beta blockade); beta blockade worsens clonidine withdrawal rebound.
