Do beta agonists increase blood pressure
WebDo beta agonists increase blood pressure? Overall, the effect of -agonists is cardiac stimulation (increased heart rate, contractility, conduction velocity, relaxation) and systemic vasodilation. Arterial pressure may increase, but not necessarily because the fall in systemic vascular resistance offsets the increase in cardiac output. WebAug 13, 2024 · Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause the heart to beat more slowly and with less force, which lowers blood pressure.
