None (5) · Selective alpha-1 adrenergic receptor antagonist. Lowers peripheral vascular resistance via vasodilation; in the CNS, blunts noradrenergic hyperarousal thought to drive trauma-related nightmares. (1) · The d-enantiomer is a highly β1-selective antagonist; the l-enantiomer triggers endothelial nitric-oxide–mediated vasodilation. Unique among beta blockers for this NO mechanism.
