Mechanism of action
Escitalopram is the active S-enantiomer of citalopram and works as a selective serotonin reuptake inhibitor (SSRI). By blocking the serotonin transporter protein, it prevents the reabsorption of serotonin from the synaptic cleft back into the presynaptic neuron, thereby increasing serotonin concentration and enhancing neurotransmission. This mechanism is thought to improve mood and reduce anxiety symptoms in depression and anxiety disorders.
