What is the mechanism of action of antihypertensive drugs?
Centrally-acting antihypertensives decrease blood pressure by diminishing sympathetic outflow from the vasomotor centre. Peripherally-acting antihypertensives act by depleting or inhibiting the release of catecholamines from the peripheral nerve ending or altering the response at alpha 1- and alpha 2-receptor sites.

What are beta blockers used for?
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.
