Name an antidepressant with strong anticholinergic properties commonly avoided in older adults.

• A. Amitriptyline
• B. Sertraline
• C. Venlafaxine
• D. Fluoxetine

Answer: (A)

Amitriptyline has strong anticholinergic activity, which is why it’s commonly avoided in older adults. Tricyclic antidepressants like amitriptyline block muscarinic receptors, leading to dry mouth, constipation, urinary retention, blurred vision, and cognitive disturbances. In older people, reduced drug clearance and increased CNS sensitivity make these effects more likely and more problematic, contributing to delirium, confusion, falls, and overall functional decline. Because of this, clinicians prefer antidepressants with minimal anticholinergic effects, such as sertraline, fluoxetine, or venlafaxine, in the elderly.
