Ipratropium is best described as which?

• A. A long-acting inhaled corticosteroid
• B. A short-acting anticholinergic used as a rescue med for COPD and asthma
• C. An oral bronchodilator
• D. Used only for allergic rhinitis

Answer: (B)

IpR atropium is a short-acting anticholinergic bronchodilator given by inhalation to quickly relieve bronchoconstriction in COPD, and it’s also used as an adjunct rescue therapy in asthma. It works by blocking acetylcholine at muscarinic receptors on airway smooth muscle, which reduces vagal-mediated bronchoconstriction and allows the airways to widen. Because it acts quickly but not for long, it’s used for immediate relief (often with a short-acting beta-agonist) rather than as a long-term controller. It’s not a long-acting inhaled corticosteroid, nor an oral bronchodilator, and while there is a nasal form for rhinorrhea, the inhaled anticholinergic used for COPD/asthma rescue fits this description best.
