Oral xanthine derivatives (theophylline and doxofylline) for patients with stable chronic obstructive pulmonary disease (COPD)
Abstract
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:
To compare the efficacy and safety of adding oral theophylline or doxofylline to usual treatment (long‐acting beta2‐agonists, antimuscarinics, inhaled corticosteroids) versus providing usual treatment alone for patients with stable COPD.
