title: [Effects of escitalopram on anxiety symptoms in depression].
abstract: Selective serotonin reuptake inhibitors, the antidepressants most widely prescribed today, exert specific action against various anxiety disorders and have an excellent acceptability profile. In addition, anxiety problems are commonly seen in depression, in the form of either characterised anxiety disorders or associated anxious symptoms. Such symptoms of anxiety result in increased risk of suicide and appear to be associated with development of more severe and chronic depressive disorders. Because of the adverse effects associated with anxiolytics, in particular benzodiazepines, their indications have been restricted. Consequently, first-line drug therapy for anxiety symptoms associated with depression involves selection of an antidepressant having anxiolytic properties. Specific serotonin reuptake inhibitors are commonly favoured at present since they have a less pronounced sedative effect than the tricyclic antidepressants (e.g. amitriptyline, maprotiline). Escitalopram, the active enantiomer of citalopram, has demonstrated efficacy and rapidity of action upon depressive symptoms seen in major depressive episodes. Global analysis of three studies comparing citalopram and escitalopram with a placebo in depressive disorders allowed specific investigation of the activity of these molecules upon the anxiety component of depressive disorders. Anxiety was quantitatively evaluated using item 6 (inner tension) of the MADRS, and for two of the three studies, using the  anxiety  sub-score of the HAM-D as well as the HAM-A total score. The results for the two active molecules demonstrate significant superiority in comparison with the placebo. Furthermore, in the case of escitalopram, this improvement appeared significant as of the first week of treatment (p<0.05); by the end of the second week of treatment, the degree of significance was even more pronounced (p<0.001). The tolerability profile of these two active substances was very good. These studies thus demonstrate the efficacy of escitalopram against anxiety symptoms associated with depression, together with particularly interesting rapidity of action. Use of an antidepressant with proven activity against anxiety accompanying depression avoids the need for co-prescription of tranquillizers, which themselves are not devoid of adverse effects.
