概要
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.
この相互作用をわかりやすく説明すると
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.
