Theovent-SR Tablet 200 mg contains Theophylline 200 mg, a long-acting bronchodilator used for the management of respiratory conditions such as asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD). This sustained-release formulation provides controlled, prolonged therapeutic effects, helping patients maintain better breathing and reduce the frequency of respiratory symptoms.

Theophylline is a xanthine derivative that works by relaxing the smooth muscles of the airways, widening the bronchial passages, and improving airflow to the lungs. Theovent-SR Tablet 200 mg is particularly beneficial for patients who require long-term maintenance therapy to manage chronic respiratory disorders, prevent asthma attacks, and improve overall lung function.

Mechanism of Action

Theophylline exerts its therapeutic effect through multiple mechanisms:

1. Bronchodilation – It relaxes smooth muscles in the airways, making it easier to breathe.
