Theophylline: Uses, Dosage, and Safety in Respiratory Care

When working with Theophylline, a methylxanthine bronchodilator prescribed for asthma and COPD. Also known as Theophyline, it helps relax airway muscles and improve breathing. Theophylline isn’t a one‑size‑fits‑all pill; it needs careful dosing and monitoring.

In practice, Bronchodilator, any medication that widens the airways is the backbone of flare‑up treatment. Theophylline belongs to this group and works differently from quick‑relief inhalers. While inhalers act within minutes, Theophylline builds up in the bloodstream and offers longer‑lasting relief. Because of that, doctors often pair it with Inhaled corticosteroids, anti‑inflammatory sprays that keep airway swelling down. The combo tackles both the muscle tightening and the inflammation that drive asthma attacks.

Why Theophylline Still Matters for Asthma and COPD

Patients with Asthma, a chronic condition causing airway hyper‑responsiveness often rely on rescue inhalers for sudden symptoms. When symptoms become frequent, adding a long‑acting bronchodilator like Theophylline can reduce the need for extra puffs. Similarly, people with COPD, a progressive lung disease linked to smoking or pollution may find Theophylline useful if inhalers alone don’t control breathlessness. The drug’s oral form also helps patients who have trouble using inhalers correctly.

However, Theophylline’s benefits come with a catch: blood levels can vary a lot between individuals. That’s why clinicians order regular blood tests to keep the concentration within the therapeutic window (typically 10‑20 µg/mL). Too low and you won’t feel relief; too high and you risk nausea, tremors, or heart rhythm issues. Lifestyle factors like caffeine intake, smoking, and certain antibiotics can shift those levels, so patients need clear guidance on what foods or drugs to avoid.

Overall, Theophylline fits into a bigger picture of respiratory care. It works alongside inhaled bronchodilators, anti‑inflammatories, and lifestyle changes to keep breathing steady.
