The molecule has been used in trials studying the treatment of Lewy Body Dementia, Visual Hallucinations, Dementia With Lewy Bodies, and REM Sleep Behavior Disorder. It is a highly selective antagonist at the 5-HT2A serotonin receptor. It increases non-REM sleep, the most restorative phase of the sleep cycle, without sacrificing REM or dream sleep.
