Nefazodone hydrochloride (BMY-13754) is a phenylpiperazine antidepressant with a mechanism of action that is distinct from those of other currently available drugs. Nefazodone hydrochloride potently and selectively blocks postsynaptic serotonin (5-hydroxytryptamine; 5-HT) 5-HT2A receptors and moderately inhibits serotonin and noradrenaline (norepinephrine) reuptake. Nefazodone hydrochloride is also an inhibitor of the hepatic P-450 isoenzyme CYP3A4.
