Protein BindingChlorpheniramine Maleate is approximately 70% bound to plasma proteins. Dextromethorphan Hydrobromide is about 60-70% bound to plasma proteins.
MetabolismChlorpheniramine Maleate is metabolized in the liver by cytochrome P450 enzymes. Dextromethorphan Hydrobromide is metabolized in the liver by CYP2D6.
Half-LifeChlorpheniramine Maleate: 12-43 hours. Dextromethorphan Hydrobromide: 2-4 hours.

How It Works

This medicine combines an antihistamine and a cough suppressant. Chlorpheniramine Maleate blocks histamine H1 receptors, reducing allergic symptoms. Dextromethorphan Hydrobromide acts on the central nervous system to suppress the cough reflex by reducing the sensitivity of cough receptors in the brain.

Mechanism Steps

1
Histamine H1 receptor blockade: Chlorpheniramine Maleate competitively blocks histamine H1 receptors on effector cells, reducing symptoms of allergic rhinitis such as sneezing and runny nose.
2
Central cough suppression: Dextromethorphan Hydrobromide acts on the cough center in the medulla oblongata to elevate the threshold for cough reflex, thereby reducing the frequency and intensity of dry cough.
