What is Quibron 300?

· Guaifenesin is an expectorant. It is used to break up congestion and mucous and to help you breathe more easily. Guaifenesin thins mucous, increases the lubrication of your respiratory tract (lungs, nose, and throat), and increases the removal of mucous.

· Theophylline is a bronchodilator. Theophylline works in several ways: It relaxes muscles in your lungs and chest to increase airflow, decreases the sensitivity of your lungs to allergens and other substances that cause inflammation, and increases the contractions of your diaphragm so that more air is drawn into the lungs.

· The combination, Quibron 300, is used to treat symptoms of asthma, bronchitis, and emphysema.
