🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAmbroxol is rapidly absorbed from the gastrointestinal tract after oral administration. Guaifenesin is also absorbed from the gastrointestinal tract. The presence of food may slightly delay the absorption of Guaifenesin but does not significantly affect the overall extent of absorption.
DistributionAmbroxol is widely distributed in body tissues, with high concentrations in the lungs, liver, and kidneys. It crosses the blood-brain barrier and placental barrier. Guaifenesin is distributed throughout the body, including the respiratory tract.
Protein BindingAmbroxol is approximately 80-90% bound to plasma proteins. Guaifenesin binding to plasma proteins is not well established.
MetabolismAmbroxol is extensively metabolized in the liver, primarily by conjugation to glucuronic acid and sulfate. Guaifenesin is metabolized in the liver via oxidation and conjugation.
Half-LifeThe elimination half-life of Ambroxol is approximately 7-12 hours. The half-life of Guaifenesin is about 1 hour.
ExcretionAmbroxol and its metabolites are excreted mainly in the urine. Guaifenesin and its metabolites are also excreted in the urine.
BioavailabilityThe oral bioavailability of Ambroxol is approximately 70-80% due to first-pass metabolism. The bioavailability of Guaifenesin is about 50%.
Onset of ActionThe onset of action for Ambroxol is typically within 30 minutes to 1 hour after oral administration. Guaifenesin may start working within 30 minutes.
Peak Plasma TimePeak plasma concentrations of Ambroxol are reached about 1-3 hours after oral administration. Guaifenesin peaks at about 0.5-1 hour.
Duration of ActionThe effects of Ambroxol last for about 6-12 hours. Guaifenesin effects last for about 4-6 hours.

How It Works

This medicine combines two active ingredients with complementary actions. Ambroxol is a mucolytic that reduces the viscosity of mucus by breaking down acidic mucopolysaccharide fibers and stimulating the production of serous fluid. It also enhances ciliary motility, helping to move mucus out of the airways. Guaifenesin is an expectorant that increases the volume and reduces the viscosity of respiratory tract secretions by drawing water into the mucus, making it thinner and easier to cough up. Together, they improve the clearance of mucus from the respiratory tract.

Mechanism Steps

1
Ambroxol breaks down mucus fibers: Ambroxol hydrolyzes acidic mucopolysaccharide fibers in mucus, reducing its thickness and stickiness.
2
Ambroxol stimulates serous secretion: It promotes the production of thinner, watery secretions in the respiratory tract, further diluting mucus.
3
Guaifenesin increases mucus hydration: Guaifenesin draws water into the mucus, increasing its volume and decreasing its viscosity.
4
Enhanced ciliary movement: Both agents improve the beating of cilia, the tiny hair-like structures that move mucus upward to be coughed out.
5
Easier expectoration: The combined effect makes it easier to cough up loosened mucus, providing symptomatic relief.
