Eftersom hepatotoksicitet har vist sig at korrelere med induktion af hepatisk neoplasi hos rotter, var denne øgede forekomst af hepatiske tumorer sandsynligvis sekundær til kronisk hepatisk toksicitet ved denne høje dosis.
Since hepatotoxicity has been shown to correlate with induction of hepatic neoplasia in rats, this increased incidence of hepatic tumors in rats was likely secondary to chronic hepatic toxicity at this high dose.
