Theophylline is a bronchodilator medication commonly used in the treatment of respiratory conditions, particularly asthma and chronic obstructive pulmonary disease (COPD). It belongs to the class of methylxanthines and works by relaxing the smooth muscles of the airways, leading to bronchodilation and improved airflow. Theophylline also has mild anti-inflammatory effects and can enhance the contractility of the diaphragm. While its use has decreased with the availability of newer respiratory medications, theophylline may still be prescribed in certain cases where other treatments are not sufficient.
