Antidepressants with strong anticholinergic activity are considered inappropriate for older adults because they:

• A. Have strong anticholinergic activity and can cause orthostatic hypotension.
• B. Are highly effective and with no risk in older adults.
• C. Do not cause sedation.
• D. Are safer than other antidepressants due to anticholinergic effects.

Answer: (A)

Older adults are highly sensitive to anticholinergic effects, which can lead to delirium, confusion, memory problems, and functional decline. Antidepressants with strong anticholinergic activity add a significant burden on the elderly’s brain and central nervous system, increasing the risk of cognitive impairment and delirium. In addition, these drugs can contribute to orthostatic hypotension, dizziness, and falls. Because of these safety concerns, Beers Criteria flags such antidepressants as inappropriate for older patients. Drugs with little anticholinergic activity are preferred instead.
