Escitalopram OxalateThird Party Manufacturing in India

Escitalopram oxalate works by selectively inhibiting the reuptake of serotonin in the central nervous system. As the pure S-enantiomer of racemic citalopram, it binds with high affinity to the serotonin transporter (SERT) on presynaptic neurons, blocking the reabsorption of serotonin into nerve cells and increasing serotonin concentration in the synaptic cleft. Escitalopram is at least 100-fold more potent than the R-enantiomer in inhibiting serotonin reuptake, making it one of the most selective SSRIs available. Unlike many other antidepressants, it exhibits minimal effects on norepinephrine and dopamine reuptake, contributing to its favourable tolerability profile. Escitalopram also demonstrates an allosteric binding mechanism at the serotonin transporter, which may explain its faster onset of clinical action compared to other SSRIs. By potentiating serotonergic activity in key brain regions, it helps restore mood regulation, reduce anxiety, and improve emotional well-being. Its high selectivity for SERT relative to off-target receptors results in fewer side effects commonly associated with less selective antidepressants.
