Lasolvan - secretomotor, secretolytic, expectorant.
Pharmacodynamics
Stimulates the serous cells of the glands of the mucous membrane of the bronchi, increases the content of mucous secretions and the release of surfactants (surfactant) in the alveoli and bronchi; normalizes the disturbed ratio of serous and mucous components of sputum. Activating hydrolytic enzymes and enhancing the release of lysosomes from Clara cells, reduces the viscosity of sputum. Increases the motor activity of cilia of the ciliated epithelium, increases mucociliary transport of sputum.
After ingestion, the action occurs after 30 minutes and lasts for 6–12 hours.
Pharmacokinetics
Absorption - high, Cmax achieved in 2 hours (for pills, syrup), for solution for ingestion and inhalation - 0.5–3 hours; binding to plasma proteins - 80% (for pills, syrup), for oral solution and inhalation - 90%. Passes through the BBB, placental barrier, excreted in breast milk. The solution for ingestion and inhalation is rapidly distributed in the tissues, the highest concentration is achieved in the lungs.
Metabolized in the liver, forms dibromantranilic acid and glucuronic conjugates. Excreted by the kidneys - 90% in the form of water-soluble metabolites, 5% - unchanged. About 30% of the dose after oral administration is eliminated by means of the primary metabolism. T1/2 - 1.3 hours, for a solution for ingestion and inhalation - 7–12 hours. There is no cumulative effect. The elimination half-life increases with severe chronic renal failure, but does not change with abnormal liver function.
