Pharmacological properties
Pharmacodynamics
Prenoxdiazine is a peripheral antitussive agent. Blocks the cough reflex due to the following effects:
- bronchodilatory action, which helps suppress stretch receptors, which are involved in the cough reflex;
- local anesthetic effect, due to which the irritability of peripheral cough receptors is reduced;
- slight suppression of the activity of the respiratory center (no respiratory depression occurs).
The antitussive effect of Libexin is approximately equal to that of codeine. The drug does not cause drug dependence and addiction. In patients with chronic bronchitis, prenoxdiazine has an anti-inflammatory effect.
The drug does not affect the functioning of the central nervous system, except for the possible indirect anti-anxiety action.
Pharmacokinetics
After oral administration, prenoxdiazine is rapidly absorbed from the gastrointestinal tract. Its maximum concentration in plasma is reached within 30 minutes after ingestion. The therapeutic concentration of prenoxdiazine is maintained for 6-8 hours. The drug is 55–59% bound to plasma proteins.
About 2/3 of the dose taken is metabolized in the liver, the rest is excreted unchanged. The half-life of prenoxdiazine is 2.6 hours. About 93% of the drug is excreted 24 hours after ingestion. After 72 hours, approximately 50–74% of prenoxdiazine is excreted in the feces, 26–50% is excreted in the urine.
Indications for use
