[Escitalopram versus serotonin reuptake inhibitors].
Escitalopram has shown some different pharmacologic properties compared to its racemic molecule, citalopram. When comparing with venlafaxine, similar efficacy of this drug was observed, notably when considering the frequency of responders [50% of decrease on the Montgomery and Asberg Depression rating Scale (MADRS)] and the frequency of remitters (MADRS<12), even when the doses of both drugs were increased up to 20 mg per day for escitalopram and 225 mg per day for venlafaxine. In addition, a recent study conducted by Jonas et al. (2006) [Jonas J, Bose A, Alexopoulos G, et al. Double blind comparison of escitalopram and duloxetine in the acute treatment of Major Depressive Disorder 45th Annual Meeting of the American College of Neuropsychopharmacology December 2006] suggested a better efficacy of escitalopram in comparison to duloxetine. When considering severe major depressive episodes, the efficacy of escitalopram compared to noradrenalin and serotonin reuptake inhibitors (NaSRI) could be superior, with a more important rate of remitters in the escitalopram group. Regarding the tolerance of both types of drugs, the percentage of patients who withdrew the drug for side-effects would be higher in patients on venlafaxine. This increase in frequency of side-effects has been observed in different studies conducted with venlafaxine and duloxetine. All these data highlight the advantages of escitalopram in the treatment of major depressive episodes and escitalopram has, therefore, obtained marketing approval in France with some specific mentions in favour of this drug.
