Oxtriphylline

Oxtriphylline is the choline salt form of [theophylline]. Once in the body, theophylline is released and acts as a phosphodiesterase inhibitor, adenosine receptor blocker, and histone deacetylase activator. Its main physiological reponse is to dilate the bronchioles. As such, oxytriphylline is indicated mainly for asthma, bronchospasm, and COPD (i.e. all the same indications as the other theophyllines). It is marketed under the name Choledyl SA, and several forms of oxytriphylline have been discontinued. In the US, oxtriphylline is no longer available. — DrugBank
