Theophylline [CAS: 58-55-9] is an orally ingested xanthine derivative prescribed to alleviate symptoms and address reversible airflow obstruction associated with chronic asthma and other chronic respiratory conditions like emphysema and bronchitis.

Theophylline: Use and Commercial Availability   

Theophylline, a xanthine derivative, manages asthma and bronchospasm. It exerts two distinct effects on the airways of individuals with reversible (asthmatic) obstruction. Firstly, it promotes smooth muscle relaxation, leading to bronchodilation. Secondly, it suppresses the airway’s response to stimuli, providing non-bronchodilator prophylactic effects. It treats asthma.

Theophylline is available under Bronkodyl, Duraphyl, Elixicon, Labid, etc., which contains the active ingredient, Theophylline.

Theophylline Structure and Mechanism of Action

The chemical name of Theophylline is 3,9-Dihydro-1,3-dimethyl-1H-purine-2,6-dione. Its chemical formula is C7H8N4O2, and its molecular weight is approximately 180.16 g/mol.

Theophylline causes bronchodilation by blocking type III and type IV phosphodiesterase (PDE), an enzyme found in smooth muscle cells.

Theophylline Impurities and Synthesis

During the Theophylline preparation1, impurity formation is possible, compromising its effectiveness. They can arise from various sources, including the raw materials, intermediates, and chemicals utilized to synthesize Theophylline. Close management and monitoring of impurities ensure the drug’s efficacy and safety.

Daicel offers a wholesome and integrated Certificate of Analysis (CoA) for Theophylline impurity standards, encompassing 1,3-dimethyl uric acid and 3-Methyl Xanthine. The CoA provides detailed characterization data, including 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. Additionally, we give a detailed 13C-DEPT on delivery. With advanced technology and expertise, Daicel can synthesize any unknown Theophylline impurity or degradation product.
