      Mechanism 3 Potentiate the bradycardia effect of beta blocker Bradycardia
Beta adrenergic receptor  Antagonist
      Key Mechanism Factor 3
Factor Name Adrenergic receptor beta Structure Sequence
Protein Family G-protein coupled receptor 1 family
Protein Function
Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. This receptor binds epinephrine and norepinephrine with approximately equal affinity. Mediates Ras activation through G(s)-alpha- and cAMP-mediated signaling. Involved in the regulation of sleep/wake behaviors (PubMed:31473062).

Recommended Action
      Management Caution is advised if beta-blockers, including ophthalmic formulations, are prescribed in combination with sympathetic ganglion-blocking or catecholamine-depleting agents. Patients should contact their doctor if they experience dizziness, lightheadedness, syncope, bradycardia, shortness of breath, difficulty breathing, edema, and/or chest pain.
