Der var en øget incidens af tumorer (hepatocellulære adenomer) hos mus eksponeret gennem 2 år med høje doser (< 75 gange human eksponering), men dette blev betragtet sekundært til prasugrelinduceret enzyminduktion.
There was an increased incidence of tumours (hepatocellular adenomas) in mice exposed for 2 years to high doses (> 75 times human exposure), but this was considered secondary to prasugrel-induced enzyme-induction.
