Medicine Description theo-sr 100mg
Theo-SR 100mg Capsule is a medication that acts primarily as a bronchodilator and is classified as a methylxanthine derivative. Its mechanism of action involves the inhibition of phosphodiesterase, particularly phosphodiesterase type 4, which leads to an accumulation of cyclic adenosine monophosphate (cAMP). The increase in cAMP levels results in relaxation of bronchial smooth muscle, facilitating improved airflow in patients with obstructive airway diseases. Furthermore, theophylline exerts a stimulatory effect on the central nervous system and enhances cardiac output by promoting increased contractility of the heart muscle. It also exhibits anti-inflammatory properties that contribute to its efficacy in respiratory conditions. The drug's action on adenosine receptors results in reduced bronchoconstriction and vasodilation, further supporting its therapeutic role in managing respiratory conditions.
