S-isomer of omeprazole. Irreversibly inhibits H+/K+ ATPase (proton pump) in gastric parietal cells. More predictable pharmacokinetics than omeprazole.
More bioavailable than omeprazole. IV form available for acute GI bleeding. Long-term use may affect calcium/magnesium absorption. Rebound acid hypersecretion on discontinuation.
Species-specific contraindications and adverse-reaction reports for cat may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Esomeprazole pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cat — the rules above are the citations specific to this species, not generic recommendations.
