Theophylline helps to open up the airways in the lungs, making it easier to breathe. It does this by relaxing the muscles around the airways, which can become tight during an asthma attack or in chronic lung conditions.

Scientifically, theophylline works by inhibiting phosphodiesterase enzymes, leading to an increase in cyclic AMP levels. This results in bronchodilation and anti-inflammatory effects, which help in reducing airway constriction and improving airflow.
