🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionChlorpheniramine maleate is well absorbed from the gastrointestinal tract after oral administration. Dextromethorphan hydrobromide is also rapidly absorbed from the gastrointestinal tract.
DistributionChlorpheniramine is widely distributed throughout body tissues, including the central nervous system. Dextromethorphan is distributed to various tissues, including the brain.
Protein BindingChlorpheniramine is approximately 72% bound to plasma proteins. Dextromethorphan is about 60-70% bound to plasma proteins.
MetabolismChlorpheniramine is metabolized in the liver, primarily by CYP2D6 and CYP3A4 enzymes. Dextromethorphan undergoes extensive first-pass metabolism in the liver, primarily via CYP2D6, to its active metabolite dextrorphan.
Half-LifeThe elimination half-life of chlorpheniramine is approximately 12-15 hours. The elimination half-life of dextromethorphan is about 2-4 hours.
ExcretionChlorpheniramine and its metabolites are excreted primarily in the urine. Dextromethorphan and its metabolites are excreted mainly in the urine as glucuronide and sulfate conjugates.
BioavailabilityChlorpheniramine has a bioavailability of about 25-50% due to first-pass metabolism. Dextromethorphan has a bioavailability of approximately 10-20% due to extensive first-pass metabolism.
Onset of ActionThe onset of action for chlorpheniramine is about 30-60 minutes, while dextromethorphan begins to suppress cough within 15-30 minutes after oral administration.
Peak Plasma TimePeak plasma concentrations of chlorpheniramine are reached in about 2-6 hours. Dextromethorphan reaches peak plasma levels in about 2-3 hours.
Duration of ActionThe effects of chlorpheniramine last for about 4-6 hours, while dextromethorphan's cough suppressant effect lasts for about 4-6 hours.

How It Works

This medicine combines two active ingredients with complementary mechanisms. Chlorpheniramine maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, reducing allergic symptoms such as sneezing, runny nose, and watery eyes. Dextromethorphan hydrobromide is a centrally acting cough suppressant that acts on the cough center in the medulla oblongata to elevate the cough threshold, thereby reducing the frequency and intensity of dry cough.

Mechanism Steps

1
Histamine H1 receptor blockade: Chlorpheniramine maleate binds to and blocks histamine H1 receptors, preventing histamine from triggering allergic responses such as sneezing, runny nose, and watery eyes.
2
Central cough suppression: Dextromethorphan hydrobromide acts on the cough center in the brain to increase the cough threshold, reducing the urge to cough.
3
Anticholinergic effect: Chlorpheniramine also exhibits anticholinergic properties, which help dry up secretions in the respiratory tract.
