Pharmaceutical Information
Drug Name Escitalopram oxalate
Drug ID BADD_D00810
Description Escitalopram is a selective serotonin re-uptake inhibitor (SSRI) and the S-enantiomer of racemic [citalopram].[A185420] It is used to restore serotonergic function in the treatment of depression and anxiety.[L8513,L8516,L8522] 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.[A39738,A185819] 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.[A185726] 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.[A185825,A185726,A185822]
Indications and Usage Labeled indications include major depressive disorder (MDD) and generalized anxiety disorder (GAD). Unlabeled indications include treatment of mild dementia-associated agitation in nonpsychotic patients.
