Tiotropium is used for COPD and is not appropriate as a rescue medication. Which statement best reflects its use?

• A. It is used as a rescue medication for sudden breathing difficulty
• B. It is a short-acting bronchodilator
• C. It is a long-acting inhaled anticholinergic used to control COPD
• D. It is a systemic antibiotic

Answer: (C)

Tiotropium is a long-acting inhaled anticholinergic used for maintenance of COPD. It works by blocking acetylcholine at muscarinic receptors in the airways, which leads to sustained bronchodilation and helps reduce COPD symptoms and exacerbations when taken regularly. Because its effect is gradual and long-lasting, it does not provide rapid relief during a sudden breathing flare, so it isn’t used as a rescue medication. Rescue relief comes from fast-acting bronchodilators, typically short-acting beta-agonists. It’s also not a systemic antibiotic, nor is it intended for acute infection treatment. So the best description is that tiotropium is a long-acting inhaled anticholinergic used to control COPD.
