Pharmacological properties


Carbocysteine ​​affects the gel phase of the mucus of the respiratory tract by breaking the disulfide bridges of glycoproteins, causing thinning of the excessively viscous secretion of the bronchi, and helps to eliminate sputum.

The mucoregulatory effect of carbocysteine ​​is associated with the activation of sialic transferase, an enzyme of goblet cells of the bronchial mucosa. Carbocysteine ​​normalizes the proportion of acidic and neutral sialomucins of bronchial secretion, restores its viscosity and elasticity. It activates the activity of ciliated epithelium and improves mucociliary clearance. It promotes the regeneration of the mucous membrane of the respiratory tract, normalizes its structure, reduces goblet cell hyperplasia and, as a result, reduces mucus production. Restores the secretion of immunologically active IgA (specific protection) and the number of sulfhydryl groups of mucus components (non-specific protection). It has an anti-inflammatory effect due to the kinin-inhibiting activity of sialomucins, reducing swelling and bronchial obstruction.


When administered, carbocysteine ​​is rapidly absorbed. The peak concentration of the active substance in blood plasma is reached after 2 hours. Bioavailability is low - less than 10% of the administered dose (due to intensive metabolism in the digestive tract and the effect of the first passage through the liver).

Carbocysteine ​​and its metabolites are excreted mainly in the urine. The half-life is about 2 hours.

Clinical characteristics


Treatment of symptoms of disorders of bronchial secretion and sputum excretion, especially in acute bronchopulmonary diseases, for example, in acute bronchitis; with exacerbations of chronic diseases of the respiratory system.


  • An allergic reaction to any of the components of the drug in history (especially to methyl paraben or other salts of parahydroxybenzoate); peptic ulcer of the stomach and duodenum during exacerbation; i trimester of pregnancy due to insufficient data on teratogenic and embryotoxic effects of the drug.

Special security measures

Do not use with drugs that inhibit cough, and drugs that reduce secretion (atropine group).

Treatment should be reviewed if there is no effect or worsening of the symptoms of the disease.

Careful monitoring by a doctor is necessary when purulent sputum is excreted, high temperature.

The drug should be used with caution during the treatment of patients with a history of gastric ulcer or duodenal ulcer.

Please note that 5 ml of 2% syrup contains 1.75 g of sugar, and 15 ml of 5% syrup contains 5.25 g of sugar.

The drug contains methyl paraben, as well as the sunset yellow colorant FCF (E 110), therefore, the content of these components can cause an allergic reaction (which may occur over time).

Interaction with other drugs and other types of interactions

During treatment with carbocysteine, antitussive drugs and drugs that suppress bronchial secretion should not be used. the drug increases the effectiveness of glucocorticoid (mutually) and antibiotic therapy.
