As a member of the xanthine family, it bears structural and pharmacological similarity to caffeine. It is naturally found in black tea and green tea.

The main actions of theophylline are:

• relaxing of bronchial smooth muscle
• positive inotropic (increasing heart muscle contractility and efficiency)
• positive chronotropic (increasing heart rate)
• increase of blood pressure
• increase of renal blood flow
• some anti-inflammatory effects
