🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLevosalbutamol is rapidly absorbed from the gastrointestinal tract after oral administration. Ambroxol is also well absorbed orally. However, oral bioavailability of levosalbutamol is reduced by first-pass metabolism. Specific pharmacokinetic parameters for this combination syrup are not established from the available information.
DistributionLevosalbutamol distributes widely into body tissues, including the lungs. Ambroxol distributes into lung tissue, bronchial secretions, and plasma. Protein binding information for this combination is not established from the available information.
Protein BindingNot established from the available information.
MetabolismLevosalbutamol undergoes extensive first-pass metabolism in the liver, primarily by sulfation. Ambroxol is metabolized in the liver by conjugation. Specific metabolic pathways for this combination are not established from the available information.
Half-LifeNot established from the available information.
ExcretionLevosalbutamol and its metabolites are excreted mainly in the urine. Ambroxol is excreted primarily in the urine as metabolites. Specific excretion data for this combination are not established from the available information.
BioavailabilityNot established from the available information.
Onset of ActionBronchodilation from levosalbutamol typically begins within 15 to 30 minutes after oral administration, but the exact onset for this syrup is not established from the available information.
Peak Plasma TimeNot established from the available information.
Duration of ActionNot established from the available information.

How It Works

This medicine combines two active ingredients with complementary actions. Levosalbutamol is the active R-enantiomer of salbutamol and acts as a selective beta-2 adrenergic receptor agonist. It binds to beta-2 receptors on airway smooth muscle, stimulating intracellular cyclic AMP production, which leads to relaxation of bronchial smooth muscle and bronchodilation. Ambroxol is a mucolytic agent that reduces mucus viscosity by breaking down acidic mucopolysaccharide fibers and stimulating serous secretion. It also promotes surfactant production and enhances ciliary clearance, making mucus easier to expectorate.

Mechanism Steps

1
Beta-2 receptor binding by levosalbutamol: Levosalbutamol binds selectively to beta-2 adrenergic receptors on the surface of airway smooth muscle cells.
2
Increased cyclic AMP: Binding activates adenylate cyclase, which increases intracellular cyclic AMP levels.
3
Smooth muscle relaxation: Elevated cyclic AMP leads to relaxation of bronchial smooth muscle, resulting in bronchodilation and easier breathing.
4
Mucolytic action of ambroxol: Ambroxol breaks down acidic mucopolysaccharide fibers in mucus, reducing its viscosity and making it less sticky.
5
Enhanced mucociliary clearance: Ambroxol also stimulates serous secretion and ciliary activity, helping to move thinned mucus out of the airways.
