Product Description
Theophylline is a methylxanthine that acts as a weak bronchodilator. It is useful for chronic therapy and is not helpful in acute exacerbations.
Theophylline is a methylxanthine alkaloid that is a competitive inhibitor of phosphodiesterase (PDE; Ki = 100 μM). It is also a non-selective antagonist of adenosine A receptors (Ki = 14 μM for A1 and A2). Theophylline induces relaxation of feline bronchiole smooth muscle precontracted with acetylcholine (EC40 = 117 μM; EC80 = 208 μM). Formulations containing theophylline have been used in the treatment of asthma and chronic obstructive pulmonary disease (COPD).
Application
1.Treatment of asthma: Theophylline can help alleviate asthma symptoms by dilating the bronchial passages and increasing muscle relaxation.
2.Treatment of heart disease: Theophylline can serve as a vasodilator, helping to improve symptoms of heart disease.
3.Central nervous system stimulation: Theophylline is used in some medications as a stimulant for the central nervous system, promoting alertness and attention.
4.Regulation of fat metabolism: Theophylline can promote fat breakdown and is believed to be helpful for weight control and weight loss.
