Brodil 4 mg Tablet, manufactured by ACI Limited, contains Salbutamol as the active ingredient. Salbutamol is a selective beta-2 adrenergic receptor agonist that works by relaxing the bronchial smooth muscles, resulting in the dilation of the airways. This action helps ease breathing and alleviates symptoms associated with airway obstruction, such as those seen in asthma, COPD, and other respiratory conditions. Brodil 4 mg Tablet provides bronchodilation with a rapid onset (within 5 minutes) and a duration of 4–6 hours.
