Theophylline ER

Theophylline ER is a long-acting bronchodilator used to treat symptoms of asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles in the lungs and opening airways, making breathing easier. The medication is taken orally and is available in extended-release form, providing prolonged relief from respiratory symptoms. Regular monitoring of blood levels is required to avoid side effects and ensure effectiveness.
