Active metabolite of amitriptyline. Inhibits norepinephrine reuptake preferentially over serotonin. Anticholinergic, antihistaminic, and alpha-adrenergic blocking properties.
Cardiac toxicity risk — monitor ECG in susceptible species. Anticholinergic effects: dry mouth, urinary retention, constipation. Do not combine with MAOIs.
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? Nortriptyline 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.
