🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionDextromethorphan Hydrobromide is rapidly absorbed from the gastrointestinal tract after oral administration. Chlorpheniramine Maleate is also well absorbed orally. Food may delay the absorption of Chlorpheniramine Maleate.
DistributionDextromethorphan Hydrobromide is widely distributed in the body, including the central nervous system. Chlorpheniramine Maleate distributes into body tissues and crosses the blood-brain barrier, which contributes to its sedative effects.
Protein BindingDextromethorphan Hydrobromide is approximately 60-70% bound to plasma proteins. Chlorpheniramine Maleate is about 72% bound to plasma proteins.
MetabolismDextromethorphan Hydrobromide is extensively metabolized in the liver by cytochrome P450 enzymes, primarily CYP2D6, to its active metabolite dextrorphan. Chlorpheniramine Maleate is metabolized in the liver via N-demethylation and other pathways.
Half-LifeThe elimination half-life of Dextromethorphan Hydrobromide is approximately 2 to 4 hours. Chlorpheniramine Maleate has a half-life of about 12 to 43 hours, with considerable interindividual variability.
ExcretionDextromethorphan Hydrobromide and its metabolites are primarily excreted in the urine. Chlorpheniramine Maleate is excreted mainly in the urine as unchanged drug and metabolites.
BioavailabilityThe oral bioavailability of Dextromethorphan Hydrobromide is approximately 10-20% due to first-pass metabolism. Chlorpheniramine Maleate has a bioavailability of about 25-50%.
Onset of ActionThe antitussive effect of Dextromethorphan Hydrobromide typically begins within 15 to 30 minutes after oral administration. The antihistaminic effect of Chlorpheniramine Maleate starts within 30 to 60 minutes.
Peak Plasma TimePeak plasma concentrations of Dextromethorphan Hydrobromide are reached in about 2 to 3 hours. Chlorpheniramine Maleate reaches peak plasma levels in approximately 2 to 6 hours.
Duration of ActionThe antitussive effect of Dextromethorphan Hydrobromide lasts about 4 to 6 hours. The antihistaminic effect of Chlorpheniramine Maleate lasts about 4 to 6 hours, but sedation may persist longer.

How It Works

This medicine combines two active ingredients with distinct mechanisms. Dextromethorphan Hydrobromide is a centrally acting antitussive that suppresses the cough reflex by acting on the cough center in the medulla oblongata. It is a non-opioid agent that does not cause analgesia or respiratory depression at therapeutic doses. Chlorpheniramine Maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, thereby reducing allergic symptoms such as sneezing, rhinorrhea, and lacrimation. It also possesses anticholinergic properties that contribute to drying of respiratory secretions.

Mechanism Steps

1
Cough reflex suppression: Dextromethorphan Hydrobromide acts on the cough center in the brain to reduce the sensitivity of the cough reflex.
2
Histamine receptor blockade: Chlorpheniramine Maleate blocks histamine H1 receptors, preventing histamine from causing allergic symptoms like sneezing and runny nose.
3
Anticholinergic effect: Chlorpheniramine Maleate also exhibits anticholinergic activity, which helps dry up respiratory secretions.
