Competitively blocks H2 receptors on parietal cells, reducing gastric acid secretion. Also has prokinetic activity via acetylcholinesterase inhibition.
Less drug interaction potential than cimetidine. Prokinetic effect makes it preferred over famotidine when motility enhancement also desired. Administer slowly IV. Note: human formulation withdrawn in some markets.
Species-specific contraindications and adverse-reaction reports for guinea pigs may differ from canine / feline reference data — consult the primary citations listed with each rule.

Why a species-specific page? Ranitidine pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in guinea pigs — the rules above are the citations specific to this species, not generic recommendations.
