Butalin Inhaler contains salbutamol, a bronchodilator that quickly alleviates symptoms like wheezing, coughing, and shortness of breath associated with asthma and COPD. Each inhalation delivers 100 mcg of salbutamol sulfate, with the inhaler providing up to 200 metered doses. Salbutamol works by relaxing the muscles in the airways, making breathing easier during acute episodes and preventing exercise-induced bronchospasm. .
