🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLevosalbutamol is rapidly absorbed from the gastrointestinal tract after oral administration. Ambroxol is also well absorbed orally, with peak plasma levels reached within 1 to 3 hours. Food may slightly delay absorption but does not significantly affect the extent.
DistributionLevosalbutamol distributes widely into body tissues, including the lungs. Ambroxol crosses the blood-brain barrier and placenta, and is distributed into breast milk. Both components have moderate protein binding.
Protein BindingLevosalbutamol is approximately 10% bound to plasma proteins. Ambroxol is about 90% bound to plasma proteins.
MetabolismLevosalbutamol undergoes extensive first-pass metabolism in the liver, primarily by sulfation. Ambroxol is metabolized in the liver by conjugation and oxidation.
Half-LifeThe elimination half-life of levosalbutamol is approximately 3 to 4 hours. Ambroxol has a half-life of about 7 to 12 hours.
ExcretionLevosalbutamol and its metabolites are excreted mainly in the urine. Ambroxol is excreted primarily in the urine as metabolites.
BioavailabilityOral bioavailability of levosalbutamol is approximately 40% due to first-pass metabolism. Ambroxol has an oral bioavailability of about 70 to 80%.
Onset of ActionBronchodilation from levosalbutamol begins within 15 to 30 minutes after oral administration. Ambroxol's mucolytic effect starts within 30 to 60 minutes.
Peak Plasma TimePeak plasma concentration of levosalbutamol is reached in about 1 to 2 hours. Ambroxol peaks at 1 to 3 hours.
Duration of ActionThe bronchodilator effect of levosalbutamol lasts for about 4 to 6 hours. Ambroxol's mucolytic effect lasts for about 6 to 8 hours.

How It Works

This medicine combines two active ingredients with complementary actions. Levosalbutamol is a selective beta-2 adrenergic receptor agonist that binds to beta-2 receptors on bronchial smooth muscle cells. This binding activates intracellular adenyl cyclase, which increases cyclic AMP levels, leading to relaxation of bronchial smooth muscle and bronchodilation. Ambroxol is a mucolytic and expectorant that reduces mucus viscosity by breaking down acidic mucopolysaccharide fibers and stimulating serous secretion. It also enhances ciliary motility and promotes surfactant production, which helps in the clearance of mucus from the airways. Together, they relieve bronchospasm and facilitate the removal of thick secretions.

Mechanism Steps

1
Beta-2 receptor binding by levosalbutamol: Levosalbutamol binds selectively to beta-2 adrenergic receptors on the surface of bronchial smooth muscle cells.
2
Increase in cyclic AMP: This binding activates adenyl cyclase, which raises intracellular cyclic AMP levels.
3
Bronchial smooth muscle relaxation: Elevated cyclic AMP causes relaxation of bronchial smooth muscle, leading to widening of the airways.
4
Mucolytic action of ambroxol: Ambroxol breaks down acidic mucopolysaccharide fibers in mucus, reducing its thickness and stickiness.
5
Enhanced ciliary clearance: Ambroxol stimulates ciliary movement and increases serous secretion, helping to move loosened mucus out of the airways.
