Treatment of depression with associated anxiety: comparisons of tricyclic antidepressants and selective serotonin reuptake inhibitors.
OBJECTIVE
Evidence indicates that alleviating anxiety symptoms early in the treatment of depression improves treatment compliance, limits treatment discontinuations and contributes to a positive treatment outcome. Because of their sedating effects, the tricyclic antidepressants (TCAs) have historically been the first-choice agent in treating comorbid depression and anxiety. However, a growing body of evidence suggests that the selective serotonin reuptake inhibitors (SSRIs) can also be suitable therapy.


METHODS
We reviewed literature regarding the use of TCAs and SSRIs in depressed patients with comorbid anxiety.


RESULTS
SSRIs are at least as effective as TCAs in the treatment of both overall depression as well as anxiety symptoms. TCAs can cause significant and sometimes unacceptable side effects which limit their therapeutic potential. SSRIs, on the other hand, have little or no effect on cholinergic, histaminergic or adrenergic receptors, and have a very favourable tolerability profile.


CONCLUSIONS
The traditional selection of antidepressants based on the presence or absence of anxiety has little scientific support. In considering the overall risk:benefit ratio, SSRIs should be the first line treatment for depression with associated anxiety.
