Theophylline
Theophylline is not recommended to treat COPD in Australia. Previous recommendations to use theophylline were based on a study that showed a reduced number of exacerbations in patients treated with theophylline compared to placebo1. However, patients in this study were not treated with current standard therapy for COPD (eg long-acting bronchodilators, inhaled corticosteroids [ICS]). In a 2018 study of patients with a recent history of COPD exacerbations, theophylline did not reduce the number of exacerbations in 1 year2.
