Phosphodiesterase inhibition leading to smooth muscle relaxation is its main mode of action as a broncho-dilating agent, requiring blood theophylline concentrations close to the toxic range and a consequent problem with side effects. It also has anti-inflammatory effects that occur at relatively low concentrations. Objective: To explore supporting evidence for how other properties of theophylline could be of considerable clinical utility, particularly in reducing weakness and overt sarcopenia, based on its antiinflammatory, steroid-sparing and immune-modulating properties. Methods: PUBMED and MEDLINE were scanned using the search terms: theophylline, antiinflammatory, cytokine, inflammation, ageing, sarcopenia, frailty, chronic obstructive airways disease, pulmonary rehabilitation. High quality articles were selected, read in-depth and discussed by the authors, then used as the basis for a proposition on the potential anti-inflammatory and antisarcopenic use of theophylline. Findings: The anti-inflammatory properties of theophylline are mainly mediated by histone deacetylase induction in immune competent cells with a resulting shift toward the expression of a less inflamed phenotype, including a reduction of the release of pro-inflammatory cytokines and the associated increase in anti-inflammatory cytokines. These effects occur at blood theophylline concentrations well below the range for direct broncho-dilatation. Conclusion: There are potential therapeutic benefits of theophylline that are systemic and not confined to airways inflammation in COPD. There is scope for a beneficial effect in other chronic inflammatory states and post-acute inflammation with slow resolution. There is compelling evidence that theophylline could be used for anti-inflammatory adjunctive treatment to improve independent function, muscle strength and other outcomes in individuals recovering from acute inflammatory episodes, including but not limited to exacerbations of COPD, and as a pharmaceutical intervention in support of pulmonary rehabilitation.
