Inhibits late inward sodium current (INaL) during cardiac repolarization, reducing intracellular sodium and calcium overload.
QT prolongation risk. Avoid with strong CYP3A inhibitors. Limited veterinary data — investigational use.
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? Ranolazine 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.
