🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionEsomeprazole is rapidly absorbed after oral administration, with peak plasma concentrations occurring 1 to 2 hours after dosing. The absorption is delayed by food, so it is best taken on an empty stomach. The oral bioavailability is approximately 64% after a single dose and increases to about 89% with repeated once-daily dosing due to decreased first-pass metabolism.
DistributionEsomeprazole is widely distributed in the body. The apparent volume of distribution at steady state is approximately 16 liters. It is highly bound to plasma proteins, primarily albumin.
Protein Binding97%
MetabolismEsomeprazole is extensively metabolized in the liver by the cytochrome P450 enzyme system, primarily by CYP2C19 and to a lesser extent by CYP3A4. The major metabolites are hydroxy and desmethyl metabolites, which are inactive.
Half-LifeThe elimination half-life is approximately 1.2 hours after repeated once-daily dosing. However, the duration of acid suppression is much longer due to irreversible binding to the proton pump.
ExcretionApproximately 80% of an oral dose is excreted as metabolites in the urine, and the remaining 20% is excreted in the feces. Less than 1% of the parent drug is excreted unchanged in the urine.
BioavailabilityThe absolute bioavailability is approximately 64% after a single oral dose and increases to about 89% with repeated once-daily dosing.
Onset of ActionAcid suppression begins within 1 hour after oral administration, but maximum effect may take up to 4 days of daily dosing.
Peak Plasma Time1 to 2 hours after oral administration.
Duration of ActionAcid suppression lasts for more than 24 hours due to irreversible binding to the proton pump, even though the drug is cleared from plasma in about 1.2 hours.

How It Works

Esomeprazole is a proton pump inhibitor. It works by irreversibly blocking the hydrogen-potassium adenosine triphosphatase (H+/K+ ATPase) enzyme system, also known as the proton pump, in the parietal cells of the stomach. This enzyme is responsible for the final step in gastric acid secretion. By inhibiting this pump, esomeprazole reduces both basal and stimulated acid secretion, leading to decreased stomach acid levels.

Mechanism Steps

1
Prodrug activation: Esomeprazole is a weak base that accumulates in the acidic environment of the parietal cell canaliculi, where it is converted to its active form.
2
Covalent binding: The active form binds covalently to sulfhydryl groups of cysteine residues on the H+/K+ ATPase pump.
3
Irreversible inhibition: This binding irreversibly inhibits the pump, blocking the final step of acid secretion.
4
Acid suppression: As a result, both basal and stimulated gastric acid secretion are suppressed, leading to reduced stomach acidity.
