Used to treat respiratory conditions with excessive mucus production, such as bronchitis, asthma, and chronic obstructive pulmonary disease (COPD). It works by thinning and loosening mucus in the airways, making it easier to cough out. Also has anti-inflammatory and antioxidant effects that help reduce airway irritation. Commonly found in cough syrups, tablets, and inhalation solutions. Often prescribed in both acute and chronic lung diseases to improve clearance of secretions and support easier breathing.
