pharmachologic effect

Pharmacodynamics. Acetylcysteine ​​is a derivative of the amino acid cysteine. The mucolytic action of acetylcysteine ​​is due to its chemical structure: a free sulfhydryl group is present in the compound molecule, which breaks the disulfide bonds of the acid mucopolysaccharides of sputum. As a result, bronchial mucus becomes less viscous, which facilitates its evacuation from the bronchial lumen and expectoration. Acetylcysteine ​​acts on the sputum of both mucous and purulent character.

Sulfigdril groups of acetylcysteine ​​molecules are able to bind chemical radicals, thereby neutralizing their negative effect on the body and providing an antioxidant effect. In addition, acetylcysteine ​​enhances the synthesis of glutathione - one of the main protective factors of the body, has an antitoxic effect. During diseases of the respiratory tract oxidative stress and general intoxication of the body takes place. Providing antioxidant and antitoxic effects, acetylcysteine ​​prevents the pathology from becoming chronic and accelerates the patient's recovery.

Pharmacokinetics. The drug is rapidly absorbed, is broken down in the liver to a pharmacologically active metabolite of cysteine ​​and inactive compounds - diacetylcysteine, cystine, and subsequently - mixed disulfides. Bioavailability is about 10%. 1-3 hours after the application of the agent, the concentration of the active substance in the blood plasma reaches a maximum. 50% of acetylcysteine ​​binds to blood proteins. After cleavage and therapeutic action, inactive acetylcysteine ​​metabolites are excreted by the kidneys. The half-life is about 60 minutes. When functional disorders of the liver, this time is increased to 8 hours.

  • ACC Long tablets contain sodium compounds, which should be taken into account by patients on a salt-free diet;
  • acetylcysteine ​​affects histamine metabolism, so you should not take tablets for a long time for patients with histamine intolerance - this can lead to symptoms of hypersensitivity (itching, rhinitis, headache);
  • when prescribing ACC Long for patients with obstructive bronchitis and bronchial asthma, strict systematic control of bronchial patency is required;
  • ACC Long tablets contain lactose, therefore they are not prescribed to patients with rare hereditary forms of galactose intolerance, lactase deficiency or glucose-galactose malabsorption syndrome;
