Pharmacological action of

Acetylcysteine ​​is a derivative of the amino acid cysteine. It has a mucolytic effect, facilitates sputum discharge due to a direct effect on the rheological properties of sputum. The action is due to the ability to break the disulfide bonds of mucopolysaccharide chains and cause depolymerization of mucoproteins of sputum, leading to a decrease in sputum viscosity. The drug remains active in the presence of purulent sputum. It has an antioxidant effect, based on the ability of its reactive sulfhydryl groups (SH-groups) to bind to oxidative radicals and, thus, neutralize them. In addition, acetylcysteine ​​promotes the synthesis of glutathione, an important component of the antioxidant system and chemical detoxification of the body. The antioxidant effect of acetylcysteine ​​increases the protection of cells from the damaging effects of free radical oxidation, which is characteristic of an intense inflammatory reaction. With the prophylactic use of acetylcysteine, there is a decrease in the frequency and severity of exacerbations of bacterial etiology in patients with chronic bronchitis and cystic fibrosis
