Lazolvan, tablets 30 mg 20 pcs

Ambroxol is the active ingredient of the drug Lazolvan. It has secretomotor, secretolytic and expectorant action. It stimulates the serous cells of the glands of the bronchial mucosa.

Ambroxol increases the production of pulmonary surfactant, stimulates ciliary activity and normalizes the disturbed ratio of serous and mucous components of sputum. By activating hydrolyzing enzymes and enhancing the release of lysosomes from Clara cells, it reduces the viscosity of sputum. Ambroxol increases the flow and transport of mucus (mucociliary clearance). Increasing mucociliary clearance improves sputum discharge and makes it easier to cough.

Pharmacokinetics

Ambroxol is characterized by rapid and almost complete absorption with a linear dose-response in the therapeutic concentration range. Cmax with oral administration is reached after 1-2.5 hours. Vd after oral administration is 552 l. In the therapeutic range of concentrations binding to plasma proteins 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 undergoes primary metabolism.

Studies on human liver microsomes have shown that CYP3A4 is the predominant isoform responsible for metabolizing ambroxol to dibromanthranilic acid. The remainder of ambroxol is metabolized in the liver primarily by glucuronidation and by partial cleavage to dibromanthranilic acid (approximately 10% of the administered dose) and a small number of additional metabolites. The terminal T1/2 of ambroxol is 10 h. Total clearance is within 660 ml/min, renal clearance accounts for approximately 8% of total clearance.

There has been no clinically significant effect of age and sex on the pharmacokinetics of ambroxol, so there is no reason to make any dosage change based on these characteristics.

In patients with hepatic impairment, ambroxol excretion is delayed, resulting in a 1.3-2-fold increase in plasma ambroxol levels. Due to the wide therapeutic range of ambroxol, no dose reduction is required.
