Triazoledione (developmental code name BMS-180492) is a phenylpiperazine compound and a major metabolite of the antidepressant nefazodone.^[2]^[3] It is active, but with substantially reduced potency compared to nefazodone (approximately one-seventh).^[3]^[2] As such, it has been suggested that it is unlikely that triazoledione contributes significantly to the pharmacology of nefazodone.^[3] However, triazoledione may reach concentrations as great as 10 times those of nefazodone, and hence could still be a significant contributor to its therapeutic effects.^[2]

H₁	11	Guinea pig	^[5]
mAChTooltip Muscarinic acetylcholine receptor	>100,000	Rat	^[5]
Values are K_i (nM). The smaller the value, the more strongly the drug binds to the site.

Triazoledione shows significant affinity for the serotonin 5-HT_1A and 5-HT_2A receptors, the α₁-adrenergic receptor, and the histamine H₁ receptor.^[3]^[5] It shows negligible affinity for the serotonin and norepinephrine transporters and the muscarinic acetylcholine receptors.^[3]^[5]
