Norepinephrine reuptake inhibitors, drug interactions

The selective serotonin reuptake inhibitors (SSRIs) are the first-line treatment of depression in the elderly. Compared with tricyciic antidepressants (TCAs), they are much safer in overdose and, for the most part, their side-effects are better tolerated. The antidepressants that have been shown, in controlled studies, to be effective in geriatric major depression are the SSRIs fluoxetine, paroxetine, and sertraline, the TCAs clomipramine and nortriptyline, and the serotonin and norepinephrine reuptake inhibitor (SNRi) venlafaxine. Given that most antidepressants are effective in the elderly, the choice of drug is based on its side-effect profile and its potential to interact with other medications.
