Theophylline(58-55-9)Asthma treatment/prevention API

Theophylline is a bronchodilator used primarily in the management of chronic respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the smooth muscles surrounding the airways, which helps open the lungs and alleviate symptoms like wheezing, shortness of breath, and chest tightness. Additionally, theophylline suppresses the lungs’ response to irritants and increases the contraction of the diaphragm, making breathing easier. Because it has a narrow therapeutic window, its use requires careful blood level monitoring to prevent toxicity.
