Used in pharmaceutical research as a selective serotonin reuptake inhibitor (SSRI) for the treatment of depression and anxiety disorders. It acts by enhancing serotonergic neurotransmission in the brain, leading to improved mood and emotional stability. Its chiral structure contributes to higher potency and fewer side effects compared to racemic counterparts. Investigated for use in central nervous system (CNS) therapies due to its ability to cross the blood-brain barrier effectively. Also explored in the development of novel antidepressants with faster onset of action.
