    22 de ago. de 2023 · Objectives: Summarize the mechanism of action of the beta-blocker class of medications, including the difference between selective and non-selective agents. Identify the indications for beta-blocker therapy. Review the adverse events, contraindications, toxicities, and interactions of beta-blockers.

    Beta blockers are competitive antagonists that block the receptor sites for the endogenous catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline) on adrenergic beta receptors, of the sympathetic nervous system, which mediates the fight-or-flight response.

    Beta-blockers are widely used molecules that are able to antagonize β-adrenergic receptors (ARs), which belong to the G protein-coupled receptor family and receive their stimulus from endogenous catecholamines.

    In this review, the molecular mechanisms of β-adrenergic action in the heart, the cellular and tissue level cardiac responses to β-adrenergic stimulation, and the clinical use of β-blockers as antiarrhythmic agents are reviewed.

    Beta-blockers are a heterogeneous group of antihypertensive agents. What they have in common is competitive antagonistic action on beta-adrenoreceptors (B1, B2 and B3). They differ in their receptor selectivity, intrinsic sympathomimetic activity (ISA), vasodilating properties and metabolism.

    Beta-blockers are drugs that block beta-adrenoceptors and inhibit sympathetic effects on the heart and blood vessels. They can decrease blood pressure, heart rate, contractility, and conduction velocity, and are used to treat hypertension, angina, arrhythmias, and heart failure.
