Abstract:

Escitalopram is a new version of Celexa (Citalopram), which might give less side effects and more desirable effects.

Question:

What is escitalopram?

Answer:

Recently a new version of the selective serotonin reuptake inhibitor (SSRI) citalopram (Celexa) was approved by the American FDA (August 2002).

Escitalopram is a new patent of the widely sold citalopram. The main idea is a seperation of the two isomer molecules of the drug. Only the S-active enantiomer contributes to the antidepressant effect. By removing the inactive R-isomer the pharmacompany promises a stronger effect, faster acting and lower side effects. But there is limited knowledge about the true reasons to promote this drug. One of the main reasons will be the exclusise patent right of these drugs.
