Theophylline: A bronchodilator that relaxes the muscles in the airways, making it easier to breathe.

Terbutaline: Also a bronchodilator, working similarly to theophylline.

Treatment of reversible airway obstruction associated with asthma and chronic obstructive pulmonary disease (COPD).

Prevention of exerciseinduced bronchospasm.

Both theophylline and terbutaline are bronchodilators that work by relaxing the muscles in the airways. They achieve this by stimulating the beta-2 receptors in the lungs, which leads to the relaxation of smooth muscle in the bronchi and bronchioles. This dilation of the airways makes breathing easier by reducing resistance to airflow.

Store at room temperature, away from heat and moisture.
