Which benefit is associated with theophylline use?

Theophylline is a bronchodilator that works by relaxing the muscles around the airways, leading to widened air passages, and improving airflow in the lungs. This mechanism results in increased lung function, as it helps to alleviate symptoms associated with conditions like asthma and chronic obstructive pulmonary disease (COPD). Patients often experience better lung capacity and reduced difficulty in breathing when theophylline is used effectively. Therefore, the benefit associated with theophylline use notably includes an increase in lung function, making it a valuable medication in respiratory therapy.
