Idoxuridine Ophthalmic dosing in other species

Why a species-specific page? Idoxuridine Ophthalmic 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.
