Which term refers to a drug used to increase secretions and mucus from the bronchial tubes?

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

Answer: (B)

Expectorants are used to promote the removal of mucus from the airways. They work by increasing the amount of bronchial secretions and by thinning or loosening the mucus, making it easier to cough up and clear from the bronchial tubes. This supports productive coughing and helps relieve chest congestion. Mucolytics, in contrast, primarily break down mucus to make it less sticky; bronchodilators open up the airways by relaxing smooth muscle; antitussives suppress coughing. A common example of an expectorant is guaifenesin.
