Theophylline Medications

What is Theophylline?

Theophylline is a xanthine derivative that acts as a bronchodilator. Managing respiratory conditions where airways become narrowed or obstructed serves as its primary purpose. Relaxation of the bronchial smooth muscles and a reduction in inflammation allows air to pass more freely into the lungs.

What Theophylline is used for

Patients use this medication for long-term control of Asthma and the management of Chronic Obstructive Pulmonary Disease. Sustained airway support rather than immediate relief during a sudden attack remains the primary intention. Individuals often rely on it to reduce the frequency and severity of respiratory symptoms.

How does Theophylline work?

Theophylline stops the action of phosphodiesterase, an enzyme in the body, which leads to increased relaxation in the smooth muscles wrapping the bronchial tubes. This process widens the airways, making it easier for oxygen to reach the lungs and for carbon dioxide to be exhaled.

Theophylline brands and forms

Options available in our Respiratory Health catalogue focus on ensuring consistent medication release into the system. Brands like Nuelin Sa and Slo-phyllin appear frequently for their reliable formulations. Variations include the following forms: modified-release capsule, hard, and modified-release tablet. These engineered forms release the drug gradually, providing sustained relief throughout the day rather than a sudden spike in blood concentration.
