Antidepressants in the elderly.
Antidepressants are effective in the treatment of depression but their use in the elderly merits special attention. In general, the tertiary amine tricyclic antidepressants (TCAs) tend to produce significant side-effects in the elderly. In contrast, nortriptyline, desipramine and lofepramine are better tolerated than other TCAs. The newer antidepressants including the selective serotonin reuptake inhibitors are useful alternatives in the treatment of depression in the elderly. As pharmacokinetic studies show that higher steady-state plasma levels of tertiary amine antidepressants may be found in the elderly than in the younger population, a lower dosage is recommended. However, the need for a lower dose in the elderly is less certain for the secondary amine TCAs. The optimum duration of continuation and maintenance antidepressant therapy requires further study. For delusional depression, there is evidence to support the superiority of ECT and combination antipsychotic/antidepressant treatment over antidepressant alone. The ultimate choice of antidepressant will be a balance of efficacy, safety, acceptability and cost.
