How it works

This product’s leaflet is published as a scanned document. This section quotes the US prescribing label for the same active substance (omeprazole). It describes the substance, not this Bulgarian product — its uses and doses can differ.

Omeprazole 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.

Because this enzyme system is regarded as the acid (proton) pump within the gastric mucosa, omeprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the final step of acid production.

How the body breaks it down

Omeprazole is extensively metabolized by the cytochrome P450 (CYP) enzyme system.

How it leaves the body

Following single dose oral administration of a buffered solution of omeprazole, little if any unchanged drug was excreted in urine.
