Ipratropium Bromide class is:

Ipratropium Bromide class is:

• A. Bronchodilator, anticholinergic, short acting antimuscarinic agent
• B. Corticosteroid
• C. Beta-adrenergic agonist
• D. Opioid analgesic

Answer: (A)

The main concept here is understanding the pharmacologic class and mechanism of ipratropium bromide. It is a bronchodilator with anticholinergic properties, specifically a short-acting muscarinic antagonist. It works by blocking acetylcholine at muscarinic receptors (primarily M3) on airway smooth muscle, which reduces parasympathetic-induced bronchoconstriction and relaxes the airways. This makes it useful for acute bronchospasm and in COPD management when rapid bronchodilation is needed. It is not a corticosteroid (which would reduce inflammation), not a beta-adrenergic agonist (which work by stimulating beta receptors to relax smooth muscle), and not an opioid analgesic. Inhaled ipratropium typically starts working within about 15 minutes and lasts around 4 to 6 hours, and is often used alongside a fast-acting beta-agonist for symptom relief.
