What does it do?

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.
