text: Mechanism of Action: Selective & competitive antagonist of α1 adrenergic receptors (~1000-fold selectivity) (Robertson & Biaggioni, 2015) block of α1-mediated sympathetic tone relaxes smooth muscle of both resistance vessels (arterioles) & veins (Robertson & Biaggioni, 2015) hypotensive effects are not accompanied by a reflex tachycardia (e.g. as compared to a non-selective α-blocker, or direct arterial vasodilators) (see Tables 1 & 2)
