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 (famotidine). It describes the substance, not this Bulgarian product — its uses and doses can differ.

Famotidine is a competitive inhibitor of histamine-2 (H 2 ) receptors.

The primary clinically important pharmacologic activity of famotidine is inhibition of gastric secretion.

Half-life2.5–3.5 h
Mostly cleared after≈ 15 hfive half-lives — our arithmetic
How it leaves the body

Famotidine is eliminated by renal (65 to 70%) and metabolic (30 to 35%) routes.

With food

Bioavailability may be slightly increased by food, or slightly decreased by antacids; however, these effects are of no clinical consequence.
