Clozapine is best described as which type of agent?

• A. Antipsychotic with strong anticholinergic properties
• B. Antimuscarinic for urinary incontinence
• C. Antispasmodic
• D. Skeletal muscle relaxant

Answer: (A)

Clozapine is an antipsychotic with relatively strong anticholinergic (antimuscarinic) effects. While its main action is as an atypical antipsychotic that blocks dopamine D2 and serotonin 5-HT2 receptors, it also tends to block muscarinic receptors more than many other antipsychotics. This adds anticholinergic side effects such as dry mouth, constipation, urinary retention, blurred vision, and potential cognitive or delirium risks, which is particularly important to consider in older adults. Therefore, describing it as an antipsychotic with strong anticholinergic properties best captures its pharmacologic profile. It is not chiefly an antimuscarinic for urinary incontinence, nor an antispasmodic, nor a skeletal muscle relaxant.
