Remedies for coughs and colds. Mucolytics. Acetylcysteine.

N-acetyl-L-cysteine (AC) has a marked mucolytic effect on mucous and mucopurulent secretions due to depolymerization of mucoprotein complexes and nucleic acids, which give viscosity to hyaline and purulent components of sputum and other secretions. Additional properties: reduction of induced mucocyte hyperplasia, increase of surfactant production due to stimulation of type II pneumocytes, stimulation of activity of mucociliary apparatus, which furthers the improvement of mucociliary clearance. AC also has a direct antioxidant effect due to the presence of a nucleophilic free thiol group (SH), which can directly interact with the electrophilic groups of oxidative radicals. Of particular interest is the fact that AC prevents the inactivation of α-1-antitrypsin – an enzyme that inhibits elastase – by hydrochloric acid (HOCl) - a strong oxidant produced by myeloperoxidase of active phagocytes.
