@drjaleelmohammed: Citalopram and escitalopram are both antidepressants that belong to the selective serotonin reuptake inhibitor (SSRI) class, but they differ in their chemical composition and effects. Citalopram is a racemic mixture, meaning it contains two enantiomers: the S-enantiomer and the R-enantiomer. Escitalopram, on the other hand, is the purified S-enantiomer of citalopram. The S-enantiomer is primarily responsible for the antidepressant effects, making escitalopram a more potent and targeted treatment. As a result, escitalopram often requires a lower dose to achieve the same therapeutic effect as citalopram, potentially leading to fewer side effects. Additionally, escitalopram may have a faster onset of action and is generally better tolerated. #lexapro #celexa #ssri #antidepressant #medication #MentalHealth #psychiatry #psychiatrist
