Pharmacodynamics
The active ingredient of the drug is ambroxol, which has a pronounced secretolytic and secretion-removing effect.
The medicine helps to excrete the secretion accumulated inside the bronchi, increasing the rate of mucolytic activity of the ciliated epithelium. In addition, it regulates the processes of sputum production inside the glandular cells.
Pharmacokinetics
Ambroxol is almost completely and at high speed absorbed in the gastrointestinal tract after taking the tablet orally. The bioavailability values of the substance are within 70-80%, and the protein synthesis indicators in the plasma are 75-90%. The Cmax level in the blood plasma is noted after 2 hours.
The drug quickly passes into tissues, especially into the kidneys and lungs. The half-life of ambroxol is within 10-12 hours. The drug is excreted with feces and urine (mainly in the form of non-toxic metabolic products). Approximately 90% of the consumed dose of the drug is excreted by the kidneys.
Ambroxol crosses the placenta and is also excreted in breast milk.
The drug clearance values may be reduced in people with severe forms of liver disease (by 20-40%). The half-life of the substance is extended in people with severe kidney disease.
