SEP-4199 is a non-racemic amisulpride engineered to have higher binding affinity for the 5-HT7 receptor and lower affinity for the D2 receptor compared to conventional racemic amisulpride.[1][2] It contains the R- and S-enantiomers of amisulpride in an 85:15 ratio rather than a 50:50 ratio. The modification is hoped to give the compound improved efficacy and fewer side effects.[3] It is under development for the treatment of depression in people with bipolar disorder. If approved, it would be the first amisulpride approved in the US for psychiatric indications.[2] It is in a phase III trial as of 2023.[4]
