概要
Atenolol blocks the beta effects of epinephrine, leaving alpha-mediated vasoconstriction unopposed, which can cause marked hypertension with reflex bradycardia. Beta-blockers may also reduce the effectiveness of epinephrine in anaphylaxis. Chlorthalidone-induced hypokalemia may add to arrhythmia risk.
この相互作用をわかりやすく説明すると
Atenolol-chlorthalidone and Epinephrine 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-chlorthalidone belongs to Cardiovascular; Epinephrine belongs to Endocrine.
なぜ起こるのか
Beta-1 blockade by atenolol antagonizes epinephrine's cardiac and bronchodilator effects while unopposed alpha stimulation increases vascular resistance.
対処法
Monitor blood pressure and heart rate when epinephrine is given. In anaphylaxis unresponsive to epinephrine in a beta-blocked patient, consider glucagon.
