5-nitroimidazole prodrug reduced by anaerobic organisms to cytotoxic metabolites that damage DNA and inhibit nucleic acid synthesis.
Longer half-life than metronidazole allows single-dose protocols. Avoid in animals with known nitroimidazole hypersensitivity. Neurotoxicity at high doses.
Species-specific contraindications and adverse-reaction reports for dog may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Secnidazole pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in dog — the rules above are the citations specific to this species, not generic recommendations.
