Methonac Tablet belongs to a class of drugs called 'mucolytic agents' (cough/sputum thinner), primarily used to treat respiratory diseases associated with excessive mucus. Acute respiratory diseases are initially associated with dry, irritating cough, hoarseness in laryngitis (swelling of the voice box), or burning sensation in the chest due to bronchitis (swelling of the lining of bronchial tubes). Then, wet mucus forms, and continuous coughing out of sputum occurs. In chronic respiratory diseases, both dry, irritating cough and wet cough with mucus occur.

Methonac Tablet contains 'Acetylcysteine' that works by thinning and loosening phlegm (mucus) in the lungs, windpipe, and nasal passage. Thereby, making it easier to cough out phlegm.
