A large dose equal to nine mg of caffeine per kg of body weight was as effective as an albuterol inhaler in treating or preventing EIA. Smaller amounts also reduced wheezing, coughing and other symptoms of EIA.
Timothy Mickleborough, study co-investigator at Indiana University said no additional benefit was found when caffeine was combined with an albuterol inhaler.
Mickleborough and colleagues have been investigating the efficacy of a number of nutritional factors.
This is especially important since prolonged use of daily medications can result in reduced effectiveness, and there is growing concern about the potential side effects of inhaled corticosteroid use.
The study was presented at the American College of Sports Medicine conference in Indiana during the Respiratory Session.
