I in vivo- undersøgelser hos rotter inducerede atazanavir ikke mikronukleus i knoglemarv, DNA- beskadigelse i duodenum (comet assay) eller uplanlagt DNA- reparation i leveren ved plasma - og vævskoncentrationer, der overskrider dem, der var klastogene in vitro.
In in vivo studies in rats, atazanavir did not induce micronuclei in bone marrow, DNA damage in duodenum (comet assay), or unscheduled DNA repair in liver at plasma and tissue concentrations exceeding those that were clastogenic in vitro.
