I karcinogenicitetsforsøg over lang tid med ranolazindoser på op til 50 mg/ kg/ dag (150 mg/ m2/ dag) hos mus og 150 mg/ kg/ dag (900 mg/ m2/ dag) hos rotter sås der ingen relevant stigning i forekomsten af tumor uanset type.
In long-term carcinogenicity studies at doses of ranolazine up to 50 mg/ kg/ day (150 mg/ m2/ day) in mice and 150 mg/ kg/ day (900 mg/ m2/ day) in rats, no relevant increases in the incidence of any tumour types were seen.
