What is a bronchodilator?

Bronchodilators are a group of drugs that help widen the airways in the lungs for the treatment of asthma and other conditions which constrict airflow in the lungs. Bronchodilators widen the bronchioles, to increase the flow of air and improve breathing.

What is an expectorant?

Expectorants are drugs that loosen mucus or phlegm in the lungs. Expectorants stimulate increased release of respiratory secretions. The increased release of secretions lowers the viscosity (thickness) of the bronchial secretions and permits easier removal from the respiratory tract.

An expectorant may be used with productive and non-productive coughs, to increase the amount of sputum expectorated.
