Legal status
Purported mechanism
Highly selective serotonin reuptake inhibitor. Escitalopram is the (S)-enantiomer of citalopram, which carries essentially all of the serotonin transporter (SERT) binding activity; the (R)-enantiomer contributes little SERT activity and may carry the QT-prolonging liability that prompted the FDA's 2011 citalopram dose ceiling, giving escitalopram a more favorable QT profile.0 CYP2C19 + CYP3A4 metabolism, with CPIC PGx guidance: poor CYP2C19 metabolizers have ~3-fold higher exposure and benefit from a lower starting dose; ultrarapid metabolizers may have inadequate response[1].
