🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionChlorpheniramine Maleate is well absorbed from the gastrointestinal tract. Dextromethorphan Hydrobromide is rapidly absorbed from the gastrointestinal tract.
DistributionChlorpheniramine Maleate distributes widely into body tissues. Dextromethorphan Hydrobromide crosses the blood-brain barrier and distributes into the central nervous system.
Protein BindingChlorpheniramine Maleate is approximately 72% bound to plasma proteins. Dextromethorphan Hydrobromide is approximately 60-70% bound to plasma proteins.
MetabolismChlorpheniramine Maleate is metabolized in the liver via cytochrome P450 enzymes, primarily CYP2D6. Dextromethorphan Hydrobromide is extensively metabolized in the liver by CYP2D6 to dextrorphan, its active metabolite.
Half-LifeChlorpheniramine Maleate: 12-43 hours. Dextromethorphan Hydrobromide: 2-4 hours.
ExcretionChlorpheniramine Maleate and its metabolites are excreted primarily in the urine. Dextromethorphan Hydrobromide and its metabolites are excreted in the urine.
BioavailabilityChlorpheniramine Maleate: 25-50%. Dextromethorphan Hydrobromide: 10-20% due to first-pass metabolism.
Onset of ActionChlorpheniramine: 30-60 minutes. Dextromethorphan: 15-30 minutes.
Peak Plasma TimeChlorpheniramine: 2-6 hours. Dextromethorphan: 2-3 hours.
Duration of ActionChlorpheniramine: 4-6 hours. Dextromethorphan: 3-6 hours.

How It Works

This medicine combines two active ingredients. 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 and reduce the cough reflex. Together, they provide relief from cough and associated allergic symptoms.

Mechanism Steps

1
Histamine H1 receptor blockade: Chlorpheniramine Maleate binds to histamine H1 receptors on effector cells, 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 threshold for coughing, thereby reducing the frequency and intensity of the cough reflex.
3
Anticholinergic effects: Chlorpheniramine also exhibits anticholinergic properties, which contribute to drying of respiratory secretions, further alleviating runny nose.
