Langes is a mucolytic, which contains the active ingredient carbocysteine.

Indications of the langesa

It is indicated for elimination of signs of bronchial secretion disorder, as well as sputum excretion. In particular, this applies to acute forms of bronchopulmonary pathologies (for example, the acute form of bronchitis). In addition, the medicine is used in the period of exacerbation of chronic forms of pathology of respiratory organs.

Release form

It is available in the form of a solution in vials of 60 or 200 ml. In a kit with a 60 ml vial, a dispensing syringe is attached, and a measuring cup to a 200 ml vial. It can also be contained in 15 ml sachets, inside one package - 12 sachets.


Carbocysteine has an effect on the gel stage of the passage of mucus inside the airways. It ruptures the disulfide bonds of glycoproteins, resulting in the liquefaction of the overly viscous secretion produced by the bronchi. Also, the substance helps to withdraw phlegm from the lungs.

Mukoregulatory action of the active component is due to activation of sialic transferase (this is an enzyme located inside the bronchial mucosa in enterocytes). Carbocysteine stabilizes the proportions of neutral as well as acidic sialomucins, which are secreted by the bronchi, and helps restore their elasticity with viscosity.

Stimulates the function of the ciliary epithelium, and also improves the work of the mucociliary system. It helps regenerate the mucous membranes of the respiratory ducts, heals its structure, reduces hyperplasia of enterocytes, and as a result, the production of mucus decreases.

Promotes the recovery of the secretion of the immunoactive element IgA (as a specific defense), and in addition the number of thiol groups of mucus elements (as a nonspecific defense). Has anti-inflammatory effect, which develops with the kinin-inhibiting activity of sialomucins. This helps reduce puffiness and relieve bronchial obstruction.

When administered orally, the drug is rapidly absorbed through the digestive tract. The peak level inside the plasma is observed after 2 hours. The bioavailability of carbocysteine is very low (about 10% of the dosage used), because the intestine metabolism is intensive. Also, this effect is affected by the effect of the "first passage" occurring in the liver.

The half-life is 2 hours. The excretion of the active ingredient and its decay products occurs mainly with urine.
