None (5) · 5-HT1A agonist, 5-HT2A antagonist, with weaker activity at D4 and other receptors. Net effect involves enhanced prefrontal dopaminergic/noradrenergic tone with decreased serotonergic inhibition of sexual desire. (1) · Selective alpha-1 adrenergic receptor antagonist. Lowers peripheral vascular resistance via vasodilation; in the CNS, blunts noradrenergic hyperarousal thought to drive trauma-related nightmares.
