🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is absorbed from the gastrointestinal tract after oral administration. It reaches peak levels in the blood within about 1 to 3 hours after taking a dose. Food may slightly delay the time to peak concentration but does not significantly reduce the total amount absorbed.
DistributionThis medicine is distributed throughout the body. It does not cross the blood-brain barrier to a large extent, which explains its low sedating effect. It is about 60% to 70% bound to plasma proteins.
Protein BindingApproximately 60% to 70% bound to plasma proteins, mainly albumin and alpha-1 acid glycoprotein.
MetabolismThis medicine undergoes minimal metabolism in the liver. It is primarily eliminated unchanged in the feces and urine. Because it is not heavily metabolized by liver enzymes, it has a low potential for drug interactions involving liver metabolism.
Half-LifeThe elimination half-life is approximately 14 to 16 hours in healthy adults.
ExcretionThis medicine is excreted mainly in the feces (about 80%) and to a lesser extent in the urine (about 10-12%) as unchanged drug. Renal impairment may increase blood levels, so dose adjustment may be needed in kidney disease.
BioavailabilityThe oral bioavailability of this medicine is approximately 30% to 40% when taken with water. Taking it with fruit juices may reduce absorption.
Onset of ActionThis medicine usually starts to relieve allergy symptoms within 1 hour after taking a dose.
Peak Plasma TimePeak plasma concentration is reached about 1 to 3 hours after oral administration.
Duration of ActionThe effect of this medicine lasts for about 24 hours, which allows for once-daily dosing in adults and children 12 years and older.

How It Works

This medicine works by selectively blocking histamine H1 receptors. Histamine is a chemical released by the body during allergic reactions, and it causes symptoms such as sneezing, itching, runny nose, and hives. By blocking these receptors, this medicine prevents histamine from triggering allergy symptoms. It is a second-generation antihistamine, which means it is less likely to cause drowsiness because it does not cross the blood-brain barrier easily.

Mechanism Steps

1
Histamine release during allergy: When the body encounters an allergen, immune cells release histamine into the bloodstream and tissues.
2
Histamine binds to H1 receptors: Histamine attaches to H1 receptors on blood vessels, nerve endings, and other cells, causing symptoms like sneezing, itching, and fluid leakage.
3
This medicine blocks H1 receptors: Fexofenadine binds to H1 receptors and prevents histamine from attaching to them.
4
Reduction of allergy symptoms: With histamine blocked, symptoms such as runny nose, itchy eyes, and hives are reduced.
