Which antidepressant is preferred for elderly patients due to lower anticholinergic burden?

• A. Escitalopram
• B. Amitriptyline
• C. Imipramine
• D. Paroxetine

Answer: (A)

In older adults, avoiding medications with anticholinergic effects helps reduce confusion, delirium, and cognitive decline. Escitalopram is a selective SSRI with minimal anticholinergic activity, so it treats depression without adding cognitive burden. Amitriptyline and imipramine are TCAs with strong anticholinergic effects, which can worsen confusion, dry mouth, constipation, urinary retention, and overall delirium risk in the elderly. Paroxetine has more anticholinergic activity than many other SSRIs, making it less favorable for cognitive safety in older patients. So, escitalopram is preferred because it provides antidepressant effects with the lowest anticholinergic burden among these options.
