Which of the following adrenergic inhibitors acts directly on the
blood vessels, producing vasodilation?
a) Prazosin hydrochloride (Minipress)
Minipress is a peripheral vasodilator acting directly on the blood
vessel. It is not used in angina and coronary artery disease, however,
because it induces tachycardia if not preceded by administration of
propranolol and a diuretic.
b) Reserpine (Serpasil)
Serpasil impairs synthesis and reuptake of norepinephrine.
c) Propranolol (Inderal)
Inderal blocks the beta-adrenergic receptors of the sympathetic
nervous system, especially the sympathetics to the heart, producing a
slower heart reate and lowered blood pressure.
d) Clonidine hydrochloride (Catapres)
Catapres acts through the central nervous system, apparently through
centrally mediated alpha-adrenergic stimulation in the brain, producing
blood pressure reduction.
