KEY POINT Theophylline, and its salt, aminophylline, are members of the methylxanthine group of drugs, which also includes dyphylline. They are considered ‘add on’ therapy in asthma if symptoms are not well controlled despite medium dose inhaled steroids and long acting bronchodilators in asthma and COPD. Xanthines--symptomatic or prophylactic in asthma? Chapter 8 reviews the pharmacology of the xanthine drugs, such as theophylline. Hence, if we can learn more about the mode of action of theophylline, the major anti-asthma xanthine, we may gain new insights into the mechanisms of asthma. There are multiple modes of action, and different drugs exert varying selectivities. Chest 93: 510–514, Schmedeberg O (1905) Uber die Anwendung des Theophyllins als Diuretikum. They are generally believed to act primarily by reversing the contraction of airway smooth muscle, although they may have additional properties that may be beneficial in the treatment of asthma (Barnes, 1990). Research and clinical practice. A clinical trial of 289 subjects (DB-RCT) showed a mild improvement in a persistent cough with the use of a theobromine-based compound . METHYLXANTHINE DRUGS.

Enprofylline is a new xanthine derivative that shares theophylline's bronchodilator properties but is free of theophylline's adenosine receptor antagonist activity. Unable to display preview. Bronchial asthma is characterised by hyperresponsiveness of tracheobronchial smooth muscle to a variety of stimuli, resulting in narrowing of air tubes, often accompanied by increased secretion, mucosal edema and mucus plugging. Pulm Pharmacol 2: 147–154, Crescioli S, Spinazzi A, Paleari D, Pozzan M, Mapp CE, Fabbri LM (1988) Theophylline inhibits early and late asthmatic reactions induced by allergens in atopic subjects with asthma. Directions for New Antiasthma Drugs. The xanthines, which are purine analogues, are non-selective inhibitors of phosphodiesterase and also antagonists at adenosine receptors. The methylxanthines, theophylline, and dyphylline are used in the treatment of airways obstruction caused by conditions such as asthma, chronic bronchitis, or emphysema. Owing to their ability to relax bronchial muscles, the xanthines are used chiefly in the maintenance treatment of asthma and chronic obstructive pulmonary disease.

In patients with atopic asthma the two xanthines, maintained at 2.4 |xg/ml and 10 (ig/ml plasma, respectively, prevented the allergen-induced late pulmonary response.20 This effect was also observed in sensitized guinea pigs.21 Some differences between the two drugs may exist.
