Patient summary
Theo-24 SR is theophylline at the lower 200mg modified-release strength for asthma and COPD, a xanthine that raises cyclic AMP in the airway.
Mechanism of action
Theo-24 SR acts primarily as a bronchodilator by increasing the level of cyclic adenosine monophosphate (cAMP) in smooth muscles. This mechanism relaxes bronchial muscles and exerts mild anti-inflammatory action, making it an effective treatment for chronic airflow obstruction.
