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