thumb|right|upright|Theophylline extended-release tablets in Japan Theophylline, also known as 1,3-dimethylxanthine, is a drug that inhibits phosphodiesterase and blocks adenosine receptors. It is used to treat chronic obstructive pulmonary disease (COPD) and asthma. Its pharmacology is similar to other methylxanthine drugs (e.g., theobromine and caffeine). Trace amounts of theophylline are naturally present in tea, coffee, chocolate, yerba mate, guarana, and kola nut.

== Medical uses == The main actions of theophylline involve: relaxing bronchial smooth muscle increasing heart muscle contractility and efficiency (positive inotrope) increasing heart rate (positive chronotropic) increasing blood pressure increasing renal blood flow anti-inflammatory effects central nervous system stimulatory effect, mainly on the medullary respiratory center
