Escipix (Escitalopram) is a selective serotonin re-uptake inhibitor (SSRI) and the S-enantiomer of racemic citalopram. It is used to restore serotonergic function in the treatment of depression and anxiety. Escitalopram is approximately 150 times more potent than citalopram’s R-enantiomer and is responsible for the vast majority of citalopram’s clinical activity, with some evidence suggesting that the R-enantiomer of racemic citalopram actively dampens the activity of escitalopram rather than existing simply as an inactive enantiomer. Amongst SSRIs, escitalopram exerts the highest degree of selectivity for the serotonin transporter (SERT) relative to other off-targets which may explain its lower rates of adverse effects as compared to other agents in this class. Escitalopram also differentiates itself from other SSRIs via allosteric action on its target – this may be the mechanism responsible for its observed superior efficacy and faster onset compared to other SSRIs.

MODE OF ACTION:
Escitalopram inhibits the reuptake of the neurotransmitter serotonin (5-HT) at the serotonin reuptake pump of the neuronal membrane of the presynaptic cell, thereby increasing levels of 5-HT within the synaptic cleft and enhancing the actions of serotonin on 5HT1A autoreceptors.
Unlike other SSRIs, escitalopram appears to not only bind to a primary high-affinity site on the serotonin transporter protein but also to a secondary lower-affinity allosteric site that is considered to stabilize and prolong drug binding. 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. 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.
