Theophylline-d6 is a stable isotope of theophylline, which is a drug used to treat asthma and other respiratory diseases. It is also used as a bronchial dilator, in the treatment of asthmatic attacks. Theophylline-d6 has been shown to be effective in treating children with severe asthma. Theophylline-d6 undergoes nonselective reaction monitoring using mass spectrometry, and it has been calibrated against human urine samples to determine its concentration in the body.
