Neoplasia in the rat induced by N-hydroxyphenacetin, a metabolite of phenacetin
Pathology.
1976 Jan.
Abstract
N-hydroxyphenacetin, a phenacetin metabolite, was fed to rats as a 0.05-0.5% dietary supplement. After 9 months, tumours of the liver were found in 36 of 64 animals. One animal also developed a renal tumour. No tumours were found in control animals. The findings implicate phenacetin as a carcinogen and suggest that N-hydroxyphenacetin may be the metabolite responsible.
