Methylphenidate wasn't mutagenic within the in vitro Ames reverse mutation assay or within the in vitro mouse lymphoma cell forward mutation assay. Sister chromatid exchanges and chromosome aberrations were being greater, indicative of the weak clastogenic response, within an in vitro assay in cultured Chinese Hamster Ovary (CHO) cells.

Animal Details In embryo-fetal progress reports performed in rats and rabbits, methylphenidate was administered orally at doses of as much as 75 and two hundred mg/kg/day, respectively, throughout the duration of organogenesis. Malformations (enhanced incidence of fetal spina bifida) ended up observed in rabbits at the very best dose, that's roughly 65 periods the MRHD of 60 mg/working day offered to Grown ups over a mg/m2 basis. The no outcome level for embryo-fetal progress in rabbits was sixty mg/kg/day (19 occasions the MRHD specified to Grown ups on the mg/m2 foundation). There was no evidence of morphological enhancement outcomes in rats, Despite the fact that amplified incidences of fetal skeletal versions were being noticed at the very best dose level (twelve situations the MRHD of 60 mg/working day provided to Grownups with a mg/m2 basis), which was also maternally toxic.
