Der var ingen tegn på karcinogenicitet i undersøgelser på mus og rotter ved den maksimalt tolererede dosis, selvom optagelsen af rivastigmin og dets metabolitter var lavere end den humane optagelse.
No evidence of carcinogenicity was found in studies in mice and rats at the maximum tolerated dose, although the exposure to rivastigmine and its metabolites was lower than the human exposure.
