<unk>  (INN), (also known as doxophylline) is a xanthine derivative drug used in the treatment of asthma.
It has antitussive[citation needed] and bronchodilator effects, and acts as a phosphodiesterase inhibitor.
In animal and human studies, it has shown similar efficacy to theophylline but with significantly fewer side effects.
Unlike other xanthines,<unk>  lacks any significant affinity for adenosine receptors and does not produce stimulant effects. This suggests that its antiasthmatic effects are mediated by another mechanism, perhaps its actions on phosphodiesterase.
