What is the 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.
