Dilanyl Syrup is formulated with terbutaline sulfate, a beta-2 adrenergic agonist that works by relaxing the smooth muscles surrounding the airways, leading to bronchodilation. This action helps alleviate symptoms such as wheezing, shortness of breath, and chest tightness associated with respiratory conditions like asthma, chronic bronchitis, and emphysema. Regular use as prescribed can improve breathing and enhance quality of life for individuals with obstructive airway diseases. .
