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

Side effects
According to the World Health Organization (WHO), unwanted effects are classified according to their frequency of development as follows: very often ( 1/10), often ( 1/100, <1/10), infrequently ( 1/1000, <1/100), rarely ( 1/10000, <1/1000) and very rarely (<1/10000) the frequency is unknown (the frequency of occurrence of phenomena cannot be determined based on available data). Allergic reactions infrequently: pruritus, rash, exanthema, urticaria, angioedema, decreased blood pressure, tachycardia very rare: anaphylactic reactions up to anaphylactic shock, Stevens-Johnson syndrome, toxic epidermal necrolysis (). From the respiratory system rarely: shortness of breath, bronchospasm (mainly in patients with bronchial hyperreactivity in asthma). From the gastrointestinal tract infrequently: stomatitis, abdominal pain, nausea, vomiting, diarrhea, heartburn, dyspepsia. Sensory disturbances infrequently: tinnitus. Other infrequently: headache, fever, isolated reports of the development of bleeding due to the presence of an increased sensitivity reaction, decreased platelet aggregation. Drug Interaction When acetylcysteine and antitussive agents are used at the same time, sputum stagnation may occur due to cough reflex suppression. When used with antibiotics for oral administration (penicillins, tetracyclines, cephalosporins, etc.), their interaction with the thiol group of acetylcysteine may occur, which may lead to a decrease in their antibacterial activity. Therefore, the interval between the administration of antibiotics and acetylcysteine should be at least 2 h (except cefixime and loracarbene). Concomitant use with vasodilating agents and nitroglycerin may lead to increased vasodilator action. overdose Symptoms: when mistaken or intentional overdose occurs, such as diarrhea, vomiting, stomach pain, heartburn and nausea. Treatment: symptomatic. Storage conditions The drug should be stored out of the reach of children, in a dry place at a temperature not exceeding 25 ° C.
