🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLevocetirizine is rapidly and extensively absorbed after oral administration. Phenylephrine is absorbed from the gastrointestinal tract but undergoes some first-pass metabolism. Food may delay the absorption of levocetirizine but does not significantly affect the extent of absorption.
DistributionLevocetirizine is widely distributed in the body. Phenylephrine distribution is not well characterized but is expected to distribute into tissues. Both drugs may cross the placenta and are excreted in breast milk.
Protein BindingLevocetirizine is approximately 90% bound to plasma proteins. Phenylephrine binding is not well established.
MetabolismLevocetirizine undergoes limited metabolism, primarily by oxidation and conjugation. Phenylephrine is metabolized in the liver and gut wall by monoamine oxidase and sulfotransferases.
Half-LifeThe elimination half-life of levocetirizine is approximately 6 to 8 hours in adults with normal renal function. The half-life of phenylephrine is about 2 to 3 hours.
ExcretionLevocetirizine is primarily excreted unchanged in the urine. Phenylephrine and its metabolites are excreted mainly in the urine.
BioavailabilityLevocetirizine oral bioavailability is high, approximately 90% or more. Phenylephrine oral bioavailability is low and variable due to first-pass metabolism.
Onset of ActionLevocetirizine onset of action is within 1 hour. Phenylephrine nasal decongestant effect begins within 15 to 30 minutes after oral administration.
Peak Plasma TimeLevocetirizine peak plasma concentration occurs about 1 hour after oral intake. Phenylephrine peak plasma levels are reached within 1 to 2 hours.
Duration of ActionLevocetirizine antihistaminic effect lasts for about 24 hours. Phenylephrine decongestant effect lasts for about 4 to 6 hours.

How It Works

This medicine combines two active ingredients with complementary mechanisms. Levocetirizine is a selective peripheral H1-receptor antagonist that prevents histamine from binding to H1 receptors, thereby reducing allergic symptoms such as sneezing, itching, and rhinorrhea. Phenylephrine is a direct-acting sympathomimetic amine that stimulates alpha-1 adrenergic receptors on nasal blood vessels, causing vasoconstriction and decreased nasal mucosal swelling. Together, they address both allergic and congestive components of upper respiratory symptoms.

Mechanism Steps

1
Histamine H1 receptor blockade: Levocetirizine binds to H1 receptors on effector cells, preventing histamine-induced responses like sneezing, itching, and mucus secretion.
2
Alpha-1 adrenergic receptor stimulation: Phenylephrine stimulates alpha-1 receptors on nasal blood vessels, causing vasoconstriction and reducing mucosal edema.
3
Combined symptomatic relief: The antihistaminic and decongestant actions work together to alleviate both allergic and congestive symptoms.
