text: Escitalopram is among the most effective and well-tolerated antidepressants for the short-term (acute) treatment of major depressive disorder in adults. It is also the safest one to give to children and adolescents.
  Controversy existed regarding the effectiveness of escitalopram compared with its predecessor, citalopram. The importance of this issue followed from the greater cost of escitalopram relative to the generic mixture of isomers of citalopram, prior to the expiration of the escitalopram patent in 2012, which led to charges of evergreening. Accordingly, this issue has been examined in at least 10 different systematic reviews and meta analyses. , reviews had concluded (with caveats in some cases) that escitalopram is modestly superior to citalopram in efficacy and tolerability.
