Beta blocker - Wikipedia
https://en.wikipedia.org/wiki/Beta_blocker
WebBeta blockers are known primarily for their reductive effect on heart rate, although this is not the only mechanism of action of importance in congestive heart failure. Beta blockers, in addition to their sympatholytic β 1 activity in the heart, influence the renin–angiotensin system at the kidneys.

WebJan 30, 2023 · Mechanism of Action. Beta-1 receptors are primarily found in cardiac nodal tissue, cardiac myocytes, other heart conduction pathway tissues, and kidneys. Beta-1 blockers exert their effect by binding to the beta-1 receptor sites selectively and inhibiting the action of epinephrine and norepinephrine on these sites.

https://pubmed.ncbi.nlm.nih.gov/31178382/
WebBeta-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. Upon β-AR stimulation, numerous intracellular cascades are activated, ultimately leading …

WebAug 22, 2023 · Beta blockers are medicines that lower blood pressure. They also may be called beta-adrenergic blocking agents. The medicines block the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause the heart to beat more slowly and with less force. This lowers blood pressure.

https://pubmed.ncbi.nlm.nih.gov/21125979/
WebAbstract. 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.
