🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionBromhexine is rapidly absorbed from the gastrointestinal tract after oral administration. Dextromethorphan is also rapidly absorbed from the gastrointestinal tract. The presence of food may slightly delay absorption but does not significantly affect the extent of absorption.
DistributionBromhexine is widely distributed to body tissues, including the lungs. Dextromethorphan is distributed to the brain and other tissues. Both drugs cross the blood-brain barrier to varying degrees.
Protein BindingBromhexine: Not established from the available information. Dextromethorphan: Approximately 60-70% bound to plasma proteins.
MetabolismBromhexine is extensively metabolized in the liver by first-pass metabolism to several metabolites, including ambroxol. Dextromethorphan is metabolized in the liver by CYP2D6 to dextrorphan, which is an active metabolite.
Half-LifeBromhexine: Approximately 1-2 hours. Dextromethorphan: Approximately 2-4 hours (but may be longer in poor CYP2D6 metabolizers).
ExcretionBromhexine and its metabolites are primarily excreted in the urine. Dextromethorphan and its metabolites are also excreted in the urine, mainly as glucuronide and sulfate conjugates.
BioavailabilityBromhexine: Approximately 75-80% due to first-pass metabolism. Dextromethorphan: Approximately 10-20% due to extensive first-pass metabolism.
Onset of ActionBromhexine: Within 30-60 minutes. Dextromethorphan: Within 15-30 minutes.
Peak Plasma TimeBromhexine: 1-2 hours. Dextromethorphan: 2-3 hours.
Duration of ActionBromhexine: 6-8 hours. Dextromethorphan: 3-6 hours.

How It Works

This medicine combines two active ingredients with complementary actions. Bromhexine works by increasing the production of serous fluid in the respiratory tract and breaking down acidic mucopolysaccharide fibers in mucus, thereby reducing mucus viscosity and making it easier to cough out. Dextromethorphan Hydrobromide acts on the central nervous system by binding to sigma-1 receptors and inhibiting the cough reflex at the medullary cough center. It also has mild antagonistic effects on NMDA receptors. Together, they provide both mucolytic and antitussive effects.

Mechanism Steps

1
Bromhexine breaks down mucus: Bromhexine increases serous fluid production and breaks down acidic mucopolysaccharide fibers, reducing mucus thickness and making it easier to expel.
2
Dextromethorphan suppresses cough: Dextromethorphan binds to sigma-1 receptors in the brain, inhibiting the cough reflex at the medullary cough center.
3
Combined effect: The mucolytic action of bromhexine and the antitussive action of dextromethorphan work together to relieve cough and clear airways.
