What is the purpose of an Expectorant medication?

Explanation:
Expectorants work by thinning and loosening mucus in the airways, making it easier to cough up and clear from the lungs. This helps improve airway clearance and reduces chest congestion because the mucus becomes less sticky and easier to bring to the throat. It’s not about breaking down mucus chemically (that’s a mucolytic action), nor about widening the airways (that would be a bronchodilator), nor about stopping the cough immediately (that’s an antitussive effect). So the primary purpose is to loosen phlegm to facilitate productive coughing.
