Libexin pharmachologic effect
Prenoxdiazine is a peripheral antitussive agent.

The drug Libeksin blocks the peripheral links of the cough reflex due to the following effects:

– local anesthetic effect, which reduces irritability of the peripheral sensitive (cough) receptors of the respiratory tract;
– bronchodilatory action, due to which there is a suppression of stretch receptors involved in the cough reflex;
– a slight decrease in the activity of the respiratory center (without respiratory depression). The antitussive effect of the drug is approximately equal to that of codeine.
Prenoxdiazine is not addictive and drug-dependent. In chronic bronchitis, the anti-inflammatory effect of prenoxdiazine has been noted. Prenoxdiazine does not affect the function of the central nervous system, with the exception of a possible indirect anxiolytic effect.

Unproductive cough of any origin:

catarrh of the upper respiratory tract, influenza, acute and chronic bronchitis, pneumonia, emphysema;
