노년기 우울증의 약물치료

초록

Background: Late-life depression (LLD) is one of the most common psychiatric disorders. However, LLD is often undetected or inadequately treated by clinicians. This review summarizes the recent research on pharmacotherapy for LLD, updates information on monotherapy using recommended antidepressants, and discusses the clinical features and diagnostic criteria for LLD. Current Concepts: The diagnostic criteria for depression in both elderly and young adults are identical. Clinical features of the elderly with depression more likely include more comorbid medical conditions and cognitive impairment than those of young adults. Depression in the elderly tends to have a more chronic course with frequent recurrences or relapses. Discussion and Conclusion: The current pharmacological treatment guidelines for LLD recommend the use of selective serotonin reuptake inhibitor (SSRI), serotonin-norepinephrine reuptake inhibitor, bupropion, mirtazapine, and vortioxetine as first-line medications. SSRIs, among them, are recommended first because they present fewer serious adverse effects and more clinical evidence than those of other antidepressants. Before starting antidepressant treatment for LLD, clinicians should consider patients’ comorbid medical conditions, drug interactions, possible adverse effects of antidepressants, and polypharmacy. The starting dose of antidepressants for elderly patients should be half of that prescribed for young adults to minimize the adverse effects; however, most elderly patients need the same antidepressant doses as that prescribed for young patients. After remission, a 1-year maintenance treatment is required to prevent recurrence or relapse of LLD.
