🔬 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 syrup formulation allows for rapid absorption, with peak plasma concentrations typically reached within 2 to 3 hours for chlorpheniramine and within 2 to 2.5 hours for dextromethorphan.
DistributionChlorpheniramine is widely distributed throughout the body, including the central nervous system, due to its lipophilic nature. Dextromethorphan is also distributed to the brain and other tissues. Both drugs cross the blood-brain barrier. Protein binding for chlorpheniramine is approximately 70%, while dextromethorphan is about 60-70% bound to plasma proteins.
Protein BindingChlorpheniramine: approximately 70%; Dextromethorphan: approximately 60-70%.
MetabolismChlorpheniramine is metabolized in the liver primarily by CYP2D6 and CYP3A4 enzymes. Dextromethorphan undergoes extensive first-pass metabolism in the liver, primarily by CYP2D6, to its active metabolite dextrorphan, which has antitussive activity. Genetic polymorphisms in CYP2D6 can affect the metabolism of both drugs.
Half-LifeChlorpheniramine: 12-15 hours; Dextromethorphan: 2-4 hours (but may be prolonged in poor CYP2D6 metabolizers).
ExcretionChlorpheniramine and its metabolites are excreted primarily in the urine. Dextromethorphan and its metabolites are also excreted in the urine, with a small amount in feces.
BioavailabilityChlorpheniramine: approximately 25-50% due to first-pass metabolism; Dextromethorphan: approximately 10-20% due to extensive first-pass metabolism.
Onset of ActionAntihistaminic effects: within 30-60 minutes; Antitussive effects: within 15-30 minutes.
Peak Plasma TimeChlorpheniramine: 2-3 hours; Dextromethorphan: 2-2.5 hours.
Duration of ActionChlorpheniramine: 4-6 hours; Dextromethorphan: 3-6 hours.

How It Works

This medicine contains two active ingredients with complementary mechanisms. Chlorpheniramine maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, thereby reducing allergic symptoms such as sneezing, rhinorrhea, and lacrimation. Dextromethorphan hydrobromide is a centrally acting cough suppressant that acts on the cough center in the medulla oblongata to elevate the cough threshold. It is a dextrorotatory morphinan analog and is not an opioid, but it acts on sigma-1 receptors and NMDA receptors, contributing to its antitussive effect.

Mechanism Steps

1
Histamine H1 receptor blockade: Chlorpheniramine maleate binds to and blocks histamine H1 receptors on effector cells, preventing histamine-mediated allergic responses such as vasodilation, increased vascular permeability, and sensory nerve stimulation.
2
Central cough suppression: Dextromethorphan hydrobromide acts on the cough center in the medulla oblongata to increase the cough threshold, thereby reducing the frequency and intensity of dry cough.
3
Additional receptor interactions: Dextromethorphan also interacts with sigma-1 receptors and NMDA receptors, which may contribute to its antitussive and potential neuroprotective effects.

💡 How to Take alex junior syrup
