In elderly patients, which medication class should be avoided due to anticholinergic burden?

In older adults, drugs with anticholinergic (muscarinic) effects add to a cumulative burden that increases the risk of delirium, cognitive impairment, constipation, urinary retention, and falls. Tricyclic antidepressants have strong anticholinergic properties because they block muscarinic receptors, making them particularly problematic for the elderly. That’s why they’re avoided to minimize anticholinergic burden. The other options generally lack meaningful anticholinergic activity: beta-blockers and calcium channel blockers don’t block muscarinic receptors, and most selective SSRIs have only mild to negligible anticholinergic effects (with rare exceptions like paroxetine).
