Mechanism of Action

Escitalopram, like other selective serotonin re-uptake inhibitors, enhances serotonergic activity by binding to the orthosteric (i.e. primary) binding site on the serotonin transporter (SERT), the same site to which endogenous 5-HT binds, and thus prevents the re-uptake of serotonin into the presynaptic neuron. Escitalopram, along with [paroxetine], is also considered an allosteric serotonin re-uptake inhibitor - it binds to a secondary allosteric site on the SERT molecule to more strongly inhibit 5-HT re-uptake. Its combination of orthosteric and allosteric activity on SERT allows for greater extracellular 5-HT levels, a faster onset of action, and greater efficacy as compared to other SSRIs. The sustained elevation of synaptic 5-HT eventually causes desensitization of 5-HT1A auto-receptors, which normally shut down endogenous 5-HT release in the presence of excess 5-HT - this desensitization may be necessary for the full clinical effect of SSRIs and may be responsible for their typically prolonged onset of action. Escitalopram has shown little-to-no binding affinity at a number of other receptors, such as histamine and muscarinic receptors, and minor activity at these off-targets may explain some of its adverse effects., The mechanism of antidepressant action of escitalopram, the S-enantiomer of racemic citalopram, is presumed to be linked to potentiation of serotonergic activity in the central nervous system (CNS) resulting from its inhibition of CNS neuronal reuptake of serotonin (5-HT).
