Mechanism of action

As the active S-enantiomer of citalopram, escitalopram oxalate is a selective serotonin reuptake inhibitor (SSRI) that blocks the serotonin transporter (SERT), preventing the reabsorption of serotonin from the synapse. This increases serotonin concentration and enhances neurotransmission, which is thought to improve mood and reduce anxiety symptoms. The oxalate salt formulation provides improved bioavailability and stability compared to the racemic mixture.
