Which term is used for a drug that increases secretions and mucus from the bronchial tubes?

• A. Antitussive
• B. Mucolytic
• C. Expectorant
• D. Decongestant

Answer: (C)

This question focuses on the name for a drug that increases secretions and mucus from the bronchial tubes to help clear the airways. That drug is an expectorant. Expectorants work by increasing or thinning mucus in the airways so it can be coughed up more easily, making it simpler to clear mucus from the lungs. An example is guaifenesin. Antitussives suppress coughing, so they don’t promote mucus production. Mucolytics break down mucus to lower its viscosity but don’t primarily increase mucus production. Decongestants relieve nasal congestion and aren’t aimed at bronchial secretions.
