What is ipratropium bromide doing to help asthma?

• A. This medication is a beta-agonist that dilates airway
• B. It is a corticosteroid anti-inflammatory agent
• C. This medication is an anticholinergic and is going to dilate or open up your airways
• D. It is a leukotriene receptor antagonist

Answer: (C)

Ipra­tropium bromide works as an anticholinergic bronchodilator. It blocks muscarinic receptors (mainly M3) on airway smooth muscle, preventing acetylcholine from triggering constriction. This reduces vagally mediated bronchomotor tone and opens the airways, helping relieve bronchospasm in asthma. It isn’t a beta-agonist, so it doesn’t directly stimulate receptors to relax the smooth muscle, and it isn’t anti-inflammatory like corticosteroids or a leukotriene receptor antagonist. It’s typically used as an adjunct in acute asthma or with beta-agonists to enhance bronchodilation.
