✅ Description:
Theophylline is a respiratory medicine from the xanthine class, used for managing asthma and chronic obstructive pulmonary disease (COPD). Theophylline relaxes the airway muscles, reduces inflammation, and improves airflow, making breathing easier. It is generally prescribed for long-term treatment.
- Asthma is a condition where airways narrow and swell, causing mucus buildup, coughing, wheezing, and shortness of breath.
- COPD includes progressive lung diseases like emphysema and chronic bronchitis, which can eventually block airflow and damage the lungs.
