Lubazodone (developmental code names YM-992, YM-35995) is an experimental antidepressant which was under development by Yamanouchi for the treatment for major depressive disorder in the late 1990s and early 2000s but was never marketed. It acts as a serotonin reuptake inhibitor (Ki for SERT = 21 nM) and 5-HT2A receptor antagonist (Ki = 86 nM), and hence has the profile of a serotonin antagonist and reuptake inhibitor (SARI). The drug has good selectivity against a range of other monoamine receptors, with its next highest affinities being for the α1-adrenergic receptor (Ki = 200 nM) and the 5-HT2C receptor (Ki = 680 nM). Lubazodone is structurally related to trazodone and nefazodone, but is a stronger serotonin reuptake inhibitor and weaker as a 5-HT2A receptor antagonist in comparison to them and is more balanced in its actions as a SARI. It reached phase II clinical trials for depression, but development was discontinued in 2001 reportedly due to the "erosion of the SSRI market in the United States".
