Elixophyllin

Theophylline, also known as dimethylxanthine, is a methylxanthine drug used in therapy for respiratory diseases such as COPD or asthma under a variety of brand names. Due to its numerous side effects, these drugs are now rarely used clinically. As a member of the xanthine family, it bears structural and pharmacological similarity to caffeine. It is naturally found in tea, although in trace quantities (~1mg/l), significantly less than therapeutic doses.
