None (9) · Partial agonist at D2 and 5HT1A. Antagonist at 5HT2A, α1A, α1B, α2C. More potent 5HT2A antagonism, 5HT1A partial agonism, and α1 antagonism (relative to D2 partial agonism) than aripiprazole, proposed to reduce akathisia and enhance affective/cognitive effects. (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) · Selective NET inhibitor (no significant DAT activity, distinguishes from amphetamine/methylphenidate). Also: 5HT1A receptor partial agonism, 5HT2B and 5HT7 receptor antagonism. The serotonergic actions may underlie better tolerability and possibly different efficacy spectrum than atomoxetine.
