Mucolytics are the medicines used to make the mucus less thick so that the person can easily cough up. They are prescribed to the patients suffering from long-term (chronic) cough. They are ideal to break up the mucus and clear the airways. These Mucolytics are widely used for treating respiratory conditions like cystic fibrosis, chronic obstructive pulmonary disease (COPD), and other conditions. They are prescribed to use as antioxidants for lungs.
