Medicine Description theo-sr 200mg
Theo-SR 200mg Capsule is a medication that primarily acts as a bronchodilator, belonging to the methylxanthine class. Its mechanism of action centers on the inhibition of the enzyme phosphodiesterase (PDE), which leads to the accumulation of cyclic adenosine monophosphate (cAMP) within cells. This increase in cAMP facilitates relaxation of bronchial smooth muscle, resulting in bronchodilation. Furthermore, elevated cAMP levels contribute to enhanced cardiac contractility and vasodilation. Theophylline also exerts an antagonistic effect on adenosine receptors, which diminishes adenosine's constrictive influence on smooth muscles, thereby aiding in the relaxation of bronchial passages and blood vessels. The cumulative effects of these actions make Theophylline effective in managing respiratory conditions characterized by bronchoconstriction.
