Salmolin Syrup is a bronchodilator medication containing Salbutamol, a selective β₂-adrenergic agonist. It works by relaxing the smooth muscles in the airways, leading to dilation and improved airflow. This syrup is commonly used to treat and prevent symptoms associated with asthma, chronic obstructive pulmonary disease (COPD), bronchitis, and other conditions involving reversible airway obstruction.
