Theophylline is a medicine found in a group of drugs called bronchodilators. These are medications associated with the breathing system of a human being, especially the bronchus. The problems treated by theophylline include asthma symptoms, emphysema, and bronchitis. It works by relaxing the bronchus and expanding them to allow for easy passage of air.
Theophylline is used in the treatment of airflow obstruction symptoms such as wheezing. Shortness of breath, and chest tightness associated with chronic asthma and other chronic lung diseases such as emphysema and chronic bronchitis. Theophylline is classified as bronchodilators, which functions by relaxing your bronchial smooth muscles, hence expanding the air passageways. Consequently, this eases breathing. Theophylline also improves contraction of the diaphragm which is one of the major breathing muscles in addition to decreasing the response of the nasal passages to irritants. Theophylline is best taken on an empty stomach either one hour before eating or 2 hours after eating. In case you get a stomach upset, you can opt to take the tablets with food.
