Positive benefits of theophylline in a randomized, double‐blind, parallel‐group, placebo‐controlled study of low‐dose, slow‐release theophylline in the treatment of COPD for 1 year

Abstract

Low-dose, slow-release oral theophylline is effective and well-tolerated in the long term treatment of stable COPD, although it does not improve post-bronchodilator lung function.
