NMDA receptor antagonist producing dissociative anesthesia. Provides somatic analgesia, amnesia, and catalepsy while maintaining pharyngeal reflexes.
Increases intracranial and intraocular pressure. Causes increased salivation (premedicate with anticholinergic). Eyes remain open under anesthesia — use lubricant. Do NOT use alone in dogs/cats (muscle rigidity) — combine with a sedative.
Species-specific contraindications and adverse-reaction reports for mice may differ from canine / feline reference data — consult the primary citations listed with each rule.
Ketamine dose ranges in mice, with cited source references: IM 22–44 mg/kg once; IP 100 mg/kg single induction dose, combined with xylazine. Reference ranges from cited sources — verify against current literature before clinical use.
Documented routes for Ketamine in mice: IM, IP.
Ketamine is indicated in mice for: Sedation, Injectable general anaesthesia (with xylazine).
These are general warnings for Ketamine across species; consult the mouse dosing table above for species-specific guidance. Increases intracranial and intraocular pressure. Causes increased salivation (premedicate with anticholinergic). Eyes remain open under anesthesia — use lubricant. Do NOT use alone in dogs/cats (muscle rigidity) — combine with a sedative.
Why a species-specific page? Ketamine pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in mice — the rules above are the citations specific to this species, not generic recommendations.
