Theophylline

Theophylline is a medication used primarily as a bronchodilator to manage and treat respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and sometimes chronic bronchitis or emphysema. It works by relaxing the smooth muscles of the airways, helping to open them up and making it easier to breathe. Theophylline is also thought to reduce inflammation and modulate the immune response in the airways.
