Doxofylline, a xanthine bronchodilator related to theophylline, is useful in the
treatment of asthma and similar bronchospastic disorders. It has minimal activity
on intestinal smooth muscle and the cardiovascular system, and is reportedly
devoid of the behavioral effects of theophylline.
Doxofylline is a methylxanthine bronchodilator that has been examined in clinical trials involving patients with either bronchial asthma or chronic obstructive pulmonary disease. Its mechanism of action is related to its ability to inhibit phosphodiesterase activity and, thus, increase cAMP. Compared to other xanthine derivatives, which have direct arrhythmogenic effects, doxofylline demonstrates decreased affinity towards adenosine A1 and A2 receptors, does not interfere with calcium influx into cells, and does not antagonize the action of calcium-channel blockers.
Doxofylline is a xanthine molecule that appears to be both bronchodilator and anti-inflammatory with an improved therapeutic window over conventional xanthines such as Theophylline and the evidence supporting the effects of Doxofylline in the treatment of lung diseases.
ChEBI: Doxofylline is an oxopurine that is a derivative of xanthine, methylated at N-1 and N-3 and carrying a 1,3-dioxolan-2-ylmethyl group at N-7, used in the treatment of asthma. It has a role as a bronchodilator agent, an antitussive and an anti-asthmatic drug. It is functionally related to a 7H-xanthine.
