Tedatioxetine (developmental code name Lu AA24530) is an experimental antidepressant that was discovered by scientists at Lundbeck; in 2007 Lundbeck and Takeda entered into a partnership that included tedatioxetine but was focused on another, more advanced Lundbeck drug candidate, vortioxetine.[1]

Tedatioxetine is reported to act as a triple reuptake inhibitor (serotonin > norepinephrine > dopamine) and 5-HT2A, 5-HT2C, 5-HT3, and α1A-adrenergic receptor antagonist.[2][3][4][5]

As of 2009, it was in phase II clinical trials for major depressive disorder,[5] but there have been no updates since then, and as of August 2013 it was no longer displayed on Lundbeck's product pipeline.[6][7]

On May 10, 2016, all work on tedatioxetine stopped.[8]

A Chinese patent shows that there has been interest in this compound outside of Lundbeck.[9]
