Pharmacological action

Ambroxol-active ingredient of the preparation Lasolvan. It has secretomotor, secretolytic and expectorant effects. It stimulates the serous cells of the glands of the bronchial mucosa.

Ambroxol enhances the production of pulmonary surfactant, stimulates ciliary activity and normalizes the disturbed ratio of serous and mucosal components of sputum. By activating hydrolyzing enzymes and increasing the release of lysosomes from Klara cells, it reduces the viscosity of sputum. Ambroxol increases mucus flow and transport (mucociliary clearance). Increased mucociliary clearance improves sputum discharge and eases coughing.

Pharmacokinetics

Ambroxol is characterized by rapid and almost complete absorption with a linear dose dependence in the therapeutic range of concentrations. Cmax with oral use is reached in 1-2.5 hours. Vd after oral use is 552 liters. In the therapeutic range of concentrations, plasma protein binding is approximately 90%.

The transfer of ambroxol from the blood to the tissues when administered orally is rapid. The highest concentrations of the active component of the drug are observed in the lungs. Approximately 30% of the orally administered dose is primarily metabolized.

Studies on human liver microsomes have shown that CYP3A4 is the predominant isoform responsible for the metabolism of ambroxol to dibromanthranilic acid. The remaining part of ambroxol is metabolized in the liver, mainly by glucuronidation and by partial cleavage to dibromantrapylic acid (preferably 10% of the administered dose), as well as a small number of additional metabolites. The terminal T1/2 of ambroxol is 10 hours. Total clearance is within 660 ml / min, with renal clearance accounting for approximately 8% of total clearance.

There was no clinically significant effect of age and gender on the pharmacokinetics of ambroxol, so there is no reason to change the dosage for these reasons.

In patients with hepatic insufficiency, the excretion of ambroxol is slowed down, which leads to an increase in the level of ambroxol in plasma by 1.3-2 times. Due to the wide therapeutic range of ambroxol, no dose reduction is required.

Indications

• acute and chronic bronchitis;
• pneumonia;

Extremely rare cases of acute severe reactions of the anaphylactic type (anaphylactic shock) have been reported.

With prolonged use in high doses — heartburn, gastralgia, nausea, vomiting.

Interaction
