Mechanism of action

Citalopram selectively inhibits the reuptake of serotonin at the serotonin transporter (SERT), leading to increased serotonin concentration in the synaptic cleft. This enhanced serotonergic neurotransmission is thought to improve mood and reduce symptoms of depression and anxiety. The placebo component in this study design serves as a control to assess the true pharmacological effect of citalopram versus placebo response.
