Theophylline: Bronchodilation and Respiratory Support Explained

Theophylline is a bronchodilator that has been used for decades in the treatment of asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD). By relaxing airway muscles and improving airflow, it helps patients breathe more easily and reduces respiratory discomfort.

How Theophylline Works

Theophylline belongs to a class of drugs called methylxanthines. It works by relaxing the smooth muscles in the bronchial tubes and improving oxygen flow to the lungs. Additionally, it may reduce airway inflammation and enhance the effectiveness of the diaphragm, supporting stronger breathing.

Common Uses

Theophylline is prescribed for:

• Long-term management of asthma symptoms

• Relief of chronic bronchitis and COPD breathing issues

• Improving nighttime breathing in patients with respiratory conditions

Unlike inhalers, theophylline is usually taken orally in tablet or capsule form, providing sustained effects over time.

Dosage and Administration

The dosage of theophylline depends on age, weight, and the severity of the condition. Because blood levels must remain within a narrow therapeutic range, regular monitoring is often required. Taking it with consistent timing and following medical advice is essential for effectiveness and safety.

Safety and Side Effects

Theophylline can cause side effects if blood levels become too high. Common side effects may include nausea, insomnia, or nervousness. More serious effects, such as irregular heartbeat or seizures, may occur if levels are not properly controlled. Patients should follow their healthcare provider’s instructions closely.

Conclusion

Theophylline remains a valuable option in the management of chronic respiratory conditions. While newer medications are often preferred, it continues to play a role in bronchodilation and respiratory support for certain patients. Always use theophylline under medical supervision to ensure safe and effective results.
