BACKGROUND: We have shown that intravenous adenosine in normal subjects does not cause bronchospasm, but causes dyspnea, most likely by an effect on vagal C fibers in the lungs [Burki et al. J Appl Physiol 2005; 98:180-5]. Since airways inflammation and bronchial hyperreactivity are features of asthma, it is possible that intravenous adenosine may be associated with an increased intensity of dyspnea, and may cause bronchospasm, as noted anecdotally in previous reports.
METHODS: We compared the effects of placebo and 10 mg intravenous adenosine, in 6 normal and 6 asthmatic subjects.
RESULTS: Placebo injection had no significant (p > 0.05) effect …
