🔬 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. The onset of action for chlorpheniramine is typically within 30 to 60 minutes, and for dextromethorphan, cough suppression begins within 15 to 30 minutes.
DistributionChlorpheniramine is widely distributed throughout the body, including the central nervous system. Dextromethorphan is also distributed to the brain and other tissues. Both drugs cross the blood-brain barrier.
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 cytochrome P450 enzymes, including CYP2D6 and CYP3A4. Dextromethorphan is extensively metabolized in the liver by CYP2D6 to its active metabolite dextrorphan, which is responsible for some of its effects.
Half-LifeThe elimination half-life of chlorpheniramine is approximately 12 to 43 hours in adults, and it may be longer in children. The elimination half-life of dextromethorphan is about 2 to 4 hours in extensive metabolizers and longer in poor metabolizers.
ExcretionChlorpheniramine and its metabolites are excreted primarily in the urine. Dextromethorphan and its metabolites are also excreted in the urine, mainly 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 ActionCough suppression from dextromethorphan typically begins within 15 to 30 minutes after oral administration. Antihistaminic effects of chlorpheniramine begin within 30 to 60 minutes.
Peak Plasma TimePeak plasma concentrations of chlorpheniramine are reached in about 2 to 6 hours. Dextromethorphan reaches peak plasma levels in about 2 to 3 hours.
Duration of ActionThe antitussive effect of dextromethorphan lasts approximately 4 to 6 hours. The antihistaminic effect of chlorpheniramine lasts about 4 to 6 hours, but sedation may persist longer.

How It Works

This medicine combines two active ingredients with distinct mechanisms. Chlorpheniramine maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, reducing allergic responses such as sneezing, runny nose, and itching. Dextromethorphan hydrobromide is a centrally acting cough suppressant that acts on the cough center in the medulla oblongata to raise the threshold for coughing. Together, they provide symptomatic relief of cough and allergic symptoms.

Mechanism Steps

1
Histamine H1 receptor blockade: Chlorpheniramine maleate binds to histamine H1 receptors, preventing histamine from triggering allergic symptoms such as sneezing, runny nose, and itching.
2
Central cough suppression: Dextromethorphan hydrobromide acts on the cough center in the brain to suppress the cough reflex, reducing the frequency and intensity of coughing.
3
Anticholinergic effects: Chlorpheniramine also exhibits anticholinergic properties, which contribute to drying of respiratory secretions, further alleviating runny nose and postnasal drip.

💡 How to Take abrotus dx junior syrup
