Theophylline Nichiiko sustained release tablets 200 mg for asthma, bronchitis and emphysema
What are Theophylline Nichiiko sustained-release tablets 200 mg for asthma, bronchitis, and emphysema?
Theophylline, a derivative of xanthine, exerts its pharmacological effects by functioning as both a phosphodiesterase antagonist and a nonselective receptor antagonist. Through these mechanisms, it plays a role in modulating intracellular signal transduction pathways, promoting lipid metabolism activation, and contributing to the reduction of inflammatory responses.
The effectiveness of Theophylline tablets extends to a range of respiratory conditions, including bronchial asthma, chronic bronchitis, asthmatic bronchitis, and emphysema. Its primary therapeutic impact lies in bronchodilation, which leads to the alleviation of associated symptoms such as persistent cough, viscous phlegm production, and breathing difficulties.
Studies have indicated that Theophylline's benefits also extend to reducing the reliance on inhaled corticosteroid therapy among patients with asthma. This observation suggests that Theophylline's bronchodilatory and anti-inflammatory properties can potentially contribute to a more comprehensive management strategy for individuals affected by these respiratory disorders.
