Neuroactive steroid that modulates GABA-A receptors, producing dose-dependent sedation to general anesthesia.
Apnea with rapid IV injection — titrate slowly. No analgesic properties. Short shelf life once broached (use within 6 hours unless preserved formulation). Good safety profile in exotic species.
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? Alfaxalone 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.
