MFDS ingredient code M086745
Erdosteine is an expectorant ingredient that has mucolytic and mucus secretion regulation effects. It is primarily used to relieve cough and phlegm symptoms in respiratory diseases. It helps to lower the viscosity of mucus, aiding in phlegm expulsion.
Erdosteine reduces the stickiness of mucus, thinning phlegm. As a result, phlegm is expelled more easily from the airways, alleviating cough. It also regulates mucus secretion, improving the condition of the respiratory mucosa.
Approved uses differ by product. Check each product's information for its actual use.
Erdosteine not only thins mucus but also has mucus secretion regulation effects, differentiating it from other expectorants. Additionally, it has antioxidant properties that can help protect the respiratory mucosa.
Even with the same ingredient, strength, dosage form and how it is taken can differ.
