АЦЦ (Acetylcysteine) – лекарственное средство, обладающее
expectorant and mucolytic effect, which is assigned to
liquefaction of the viscous bronchus secretion in diseases of the organs
respiratory system, proceeding with the formation of thick, difficult
отходящей sputum

The history of the invention of the drug came in the middle of the past
century. It was then that Professor Ferrari, who worked in Italian
pharmaceutical company “Zambon”, found similarities
acetylcysteine ​​with cysteine ​​protein, which has the ability
break the mucopolysaccharide molecules of which
bronchopulmonary secret. The first drug based on acetylcysteine
wore the name Fluimucil.

pharmachologic effect

The mucolytic effect of the drug is provided by the current
substance acetylcysteine, which is a derivative of cysteine
(amino acids). Acetylcysteine ​​molecule has in its structure
sulfhydryl groups, which contributes to the disruption of disulfide
links mucopolysaccharides in the composition of sputum, which provide
viscosity of the secret. As a result, the phlegm softens and is lighter.
separated from the walls of the bronchi.

The drug has a direct effect on the thickness and rheological
sputum properties, maintaining proper activity even with purulent
impurities in the bronchial secretions. With профилактическом использовании
acetylcysteine ​​patients with cystic fibrosis and chronic bronchitis
note a decrease in the number and decrease the severity of exacerbations.


Another effect of acetylcysteine ​​is antioxidant.
pneumoprotective effect, which is implemented by binding and
decontamination of chemical radicals with sulfhydryl groups.
The drug accelerates the synthesis of glutathione, a factor of intracellular protection
from a number of cytotoxic substances and oxidative toxins
internal and external origin, which allows the use of ACC
with an overdose of paracetamol.


Quickly and fully absorbed, being metabolized in
the liver. In the course of metabolic reactions formed pharmacologically
active cysteine ​​and a number of other mixed disulfides. Bioavailability
is only about 10%. The maximum concentration is reached in
blood 1-3 hours after administration. Fiery Protein Coupling
reaches 50%. Acetylcysteine выводится почками как неактивные
metabolites. Very fast half-life of about 1 h.
объясняется биотрансформацией вещества в the liver. With дисфункции
liver this period increases to 8 h.
