Which statement differentiates tiotropium from ipratropium?

• A. Tiotropium is a short-acting inhaled bronchodilator
• B. Ipratropium is a short-acting anticholinergic used as a rescue med for COPD and asthma
• C. Ipratropium is a long-acting corticosteroid
• D. Tiotropium is an oral bronchodilator

Answer: (B)

Differentiate timing and role of anticholinergic bronchodilators. Tiotropium is a long-acting muscarinic antagonist (LAMA) given by inhalation for ongoing maintenance in COPD; it provides prolonged bronchodilation and is not used for immediate relief. Ipratropium is a short-acting anticholinergic (SAMA) that can be used as rescue therapy or adjunct in acute settings for COPD and sometimes asthma, providing quick, short-lived bronchodilation. The statement that ipratropium is a short-acting anticholinergic used as a rescue med for COPD and asthma captures this distinction. The other options misstate tiotropium’s duration or route or misidentify ipratropium’s class.
