Which statement about tiotropium is true?

• A. Short-acting inhaled beta-agonist rescue
• B. Oral antibiotic
• C. Short-acting anticholinergic
• D. A long-acting inhaled anticholinergic used to control COPD

Answer: (D)

Tiotropium is a long-acting inhaled anticholinergic bronchodilator used for maintenance in COPD. It works by blocking muscarinic receptors in the airways, which decreases bronchoconstriction and helps keep the airways open over time. Because it’s long-acting, it’s taken daily to control symptoms and reduce exacerbations, not for immediate relief during a COPD flare. That’s why the statement about tiotropium being a long-acting inhaled anticholinergic used to control COPD is correct. It is not a rescue inhaler (that role belongs to short-acting beta-agonists), not an oral antibiotic, and not a short-acting anticholinergic.
