How it works
From the US prescribing label for the same active substance (Esomeprazole Magnesium). It describes the substance, not this exact product.
Esomeprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of the gastric parietal cell.
Esomeprazole is protonated and converted in the acidic compartment of the parietal cell forming the active inhibitor, the achiral sulphenamide.
Esomeprazole is extensively metabolized in the liver by the cytochrome P450 (CYP) enzyme system.
Less than 1% of parent drug is excreted in the urine.
The AUC after administration of a single 40 mg dose of esomeprazole magnesium delayed-release capsules is decreased by 43% to 53% after food intake compared to fasting conditions [see Dosage and Administration ( 2.3 )].
