🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionChlorpheniramine is well absorbed from the gastrointestinal tract after oral administration. Phenylephrine is absorbed from the gastrointestinal tract but undergoes extensive first-pass metabolism, resulting in low oral bioavailability. Food does not significantly affect the absorption of either component.
DistributionChlorpheniramine is widely distributed throughout body tissues and crosses the blood-brain barrier. Phenylephrine distribution is not well characterized but it is known to have a large volume of distribution.
Protein BindingChlorpheniramine is approximately 70% bound to plasma proteins. Protein binding of phenylephrine is not established from the available information.
MetabolismChlorpheniramine is metabolized in the liver primarily by cytochrome P450 enzymes, including CYP2D6, to inactive metabolites. Phenylephrine undergoes extensive first-pass metabolism in the gut wall and liver, mainly by monoamine oxidase and sulfotransferases.
Half-LifeChlorpheniramine elimination half-life is approximately 12 to 43 hours in adults. Phenylephrine elimination half-life is approximately 2 to 3 hours.
ExcretionChlorpheniramine and its metabolites are excreted primarily in the urine. Phenylephrine and its metabolites are excreted mainly in the urine as sulfate conjugates.
BioavailabilityChlorpheniramine oral bioavailability is approximately 25 to 50%. Phenylephrine oral bioavailability is low, approximately 38% due to first-pass metabolism.
Onset of ActionChlorpheniramine onset of action is about 30 to 60 minutes after oral administration. Phenylephrine onset of nasal decongestion is within 15 to 30 minutes after oral administration.
Peak Plasma TimeChlorpheniramine peak plasma concentration occurs at about 2 to 6 hours. Phenylephrine peak plasma concentration occurs at about 1 to 2 hours.
Duration of ActionChlorpheniramine duration of action is about 4 to 6 hours. Phenylephrine duration of nasal decongestion is about 4 to 6 hours.

How It Works

This medicine combines two active ingredients with complementary actions. Chlorpheniramine Maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors on effector cells, reducing vascular permeability, itching, sneezing, and mucus secretion. Phenylephrine is a direct-acting sympathomimetic amine that selectively stimulates alpha-1 adrenergic receptors on nasal blood vessels, causing vasoconstriction and decreased nasal congestion. The combination provides relief from both allergic symptoms and nasal stuffiness.

Mechanism Steps

1
Histamine H1 receptor blockade: Chlorpheniramine binds to H1 receptors on smooth muscle and endothelial cells, preventing histamine from increasing vascular permeability and causing itching and sneezing.
2
Alpha-1 adrenergic receptor stimulation: Phenylephrine stimulates alpha-1 receptors on nasal mucosal blood vessels, causing vasoconstriction and reducing swelling and congestion.
3
Anticholinergic effect: Chlorpheniramine also blocks muscarinic receptors, reducing secretions in the nose and throat, which helps dry up a runny nose.
4
Central nervous system depression: Chlorpheniramine crosses the blood-brain barrier and causes sedation by blocking histamine in the central nervous system.
