None (4) · 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) · Selective inverse agonist at 5HT2A receptors with weaker activity at 5HT2C. Has no significant dopamine D2 affinity, unique among approved antipsychotics. Inverse agonism (rather than antagonism) reduces constitutive 5HT2A receptor activity below baseline. (1) · Synthetic T4 (thyroxine); peripherally deiodinated to T3 (triiodothyronine), the active hormone.
