Used primarily as a mucolytic agent, it helps in the treatment of respiratory disorders associated with thick mucus such as chronic bronchitis, asthma, and bronchiectasis. It works by breaking down and reducing the viscosity of mucus, making it easier to cough up and clear from the airways. This action improves breathing and reduces the frequency of coughing. It is commonly found in over-the-counter cough syrups and prescription medications for chest congestion. Additionally, it may enhance the effectiveness of antibiotics by improving their penetration into bronchial secretions.
