A mucolytic that has the ability to stimulate serous-type cells located on the mucous membranes of the bronchial tree. As a result, the amount of mucous discharge increases, disturbing the balance of serous and mucous components of sputum. Enzymes that are responsible for hydrolysis (dissolution of substances with water) become more active, and the viscosity of sputum weakens, the mucus becomes thinner and easier to pass.
