Which of the following is listed as an anticholinergic medication?

Explanation:
Anticholinergic medications block muscarinic acetylcholine receptors, leading to effects like dry mouth, constipation, blurred vision, urinary retention, and potential cognitive slowing. Nortriptyline, a tricyclic antidepressant, has strong muscarinic receptor antagonism, giving it notable anticholinergic properties. That’s why it’s listed as anticholinergic. The other drugs here don’t primarily act through muscarinic blockade: haloperidol is mainly a dopamine D2 blocker with minimal anticholinergic effect, atenolol is a beta-1 blocker, and albuterol is a beta-2 agonist.
