Escitalopram is a drug used to treat depression.
 As of 2012, reviews had concluded (with caveats in some cases) that escitalopram is modestly superior to citalopram in efficacy and tolerability
Of the SSRIs currently available, escitalopram has the highest selectivity for the serotonin transporter (SERT) compared to the norepinephrine transporter (NET), making the side-effect profile relatively mild in comparison to less-selective SSRIs
