    Product Description

    7-(β-Hydroxyethyl)theophylline-d6 is intended for use as an internal standard for the quantification of 7-(β-hydroxyethyl)theophylline (Item No. 28372) by GC- or LC-MS. 7-(β-Hydroxyethyl)theophylline is a methylxanthine phosphodiesterase (PDE) inhibitor.1 It reduces histamine, 5-hydroxytryptamine (5-HT), and bradykinin-induced bronchoconstriction in an anesthetized guinea pig model of bronchial asthma.2 Formulations containing 7-(β-hydroxyethyl)theophylline in combination with theophylline have been used in the treatment of asthma.
