title: [The new possibility for the treatment of acute cough].
abstract: Acute cough associated with influenza and acute respiratory viral infection (ARVI) is one of the most common complaints prompting the patient to visit a general practitioner or an otorhinolaryngologist based at the outpatient clinic. Acute cough during ARVI in the practically healthy subjects is as a rule non-productive, frequently dry, and becomes resolved within 2-3 weeks. In certain cases, however, the cough during ARVI can be productive with the well apparent abnormal expectoration of sputum especially in the aged and elderly subjects, young children, and patients suffering from the chest injuries, dry pleuritis, and other disorders. The early prescription of mucoactive preparations can prevent the development of subacute cough. In such cases, it is recommended to use the mucokinetic ambroxol that improves the mucociliary clearance (MCC) and does not require strong exertion for sputum expectoration. An important aspect in the mechanism of action of ambroxol is the stimulation of surfactant production, antioxidation effect, the improvement of rheological properties of bronchial mucus, ant-inflammatory and antiviral effects. The application of the new pharmaceutical dose form of ambroxol, neo-bronchol (orally disintegrating tablets), produces a very rapid effect (within 1 day after the intake) due to the fast absorption of this medication in the oral cavity, its rapid penetration into the circulatory system and achievement of the high concentration in blood plasma. The volatile metabolites of ambroxol that form as a result of tablet disintegration, such as ambroxol itself, menthol, and cineol, exert the mucolytic, antiseptic, and antibacterial actions, after they reach the trachea and bronchi. Irrigation of the receptors present in the inflamed mucous membrane of the larynx, pharynx, and nasal cavity, with these volatile substances produces an immediate cough-suppressive effect. It is concluded that the preparations of neo-bronchol (orally disintegrating tablets) can be recommended for the inclusion in the combined treatment of the patients presenting with acute and chronic diseases accompanied by the excretion of viscous and difficult-of-discharge bronchial mucus (such as acute and chronic bronchitis, pneumonia, chronic obstructive pulmonary disease, bronchial asthma with difficulty in sputum discharge, and bronchoectatic disease).
