Used primarily in the treatment of asthma and chronic obstructive pulmonary disease (COPD), it helps in relaxing the smooth muscles of the airways, leading to improved airflow and easier breathing. It is favored for its bronchodilatory effect with a lower incidence of central nervous system and cardiovascular side effects compared to other methylxanthines. Commonly administered orally or intravenously, it is found in tablets, syrups, and injectable solutions. Its anti-inflammatory properties also contribute to reducing airway inflammation, making it effective in managing acute exacerbations and long-term control of respiratory conditions.
