Hepatotoxicity in a rat model caused by orally administered methotrexate
Pauline de la M. Hall, Mark A. Jenner, Michael J. Ahern – 1 November 1991 – We undertook a dose‐response study in Wistar rats to develop an animal model for methotrexate hepatotoxicity. Rats were given oral methotrexate in 300, 200, 150 and 100 m̈g/kg/day doses for variable lengths of time. The 300 m̈g/kg/day dose produced systemic toxicity; the animals needed to be killed early, and hepatotoxicity was not observed.
