🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCetirizine is rapidly absorbed after oral administration, with peak plasma concentrations reached in about 1 hour. Phenylephrine undergoes extensive first-pass metabolism, resulting in low oral bioavailability.
DistributionCetirizine is widely distributed throughout the body, including the skin and nasal mucosa. Phenylephrine distribution is not well characterized but is expected to be limited due to rapid metabolism.
Protein BindingCetirizine is approximately 93% bound to plasma proteins. Phenylephrine protein binding is not established from the available information.
MetabolismCetirizine undergoes minimal hepatic metabolism. Phenylephrine is extensively metabolized in the gut wall and liver by monoamine oxidase and sulfotransferases.
Half-LifeCetirizine elimination half-life is approximately 8-10 hours in adults with normal renal function. Phenylephrine half-life is approximately 2.5-3 hours.
ExcretionCetirizine is primarily excreted unchanged in the urine. Phenylephrine metabolites are excreted in the urine.
BioavailabilityCetirizine oral bioavailability is high, approximately 70% or more. Phenylephrine oral bioavailability is low and variable, approximately 38% due to first-pass metabolism.
Onset of ActionCetirizine onset of action is within 1 hour. Phenylephrine onset of nasal decongestion is within 15-30 minutes.
Peak Plasma TimeCetirizine peak plasma time is about 1 hour. Phenylephrine peak plasma time is about 1-2 hours.
Duration of ActionCetirizine duration of action is approximately 24 hours. Phenylephrine duration of action is approximately 4-6 hours.

How It Works

Cetirizine is a selective peripheral H1-receptor antagonist that inhibits the early phase of allergic reactions by blocking histamine release from mast cells. Phenylephrine is an alpha-1 adrenergic receptor agonist that causes vasoconstriction in the nasal mucosa, reducing swelling and congestion.

Mechanism Steps

1
Histamine H1 receptor blockade: Cetirizine binds to H1 receptors on effector cells, preventing histamine from triggering allergic responses.
2
Alpha-1 adrenergic receptor activation: Phenylephrine stimulates alpha-1 receptors on vascular smooth muscle, causing vasoconstriction and reduced nasal congestion.
3
Reduction of inflammatory mediators: Cetirizine also inhibits eosinophil chemotaxis and release of inflammatory cytokines, contributing to symptom relief.
