Codeine In an embryofetal enhancement analyze in Expecting rats dosed throughout the duration of organogenesis, codeine greater resorptions and lessened fetal weights in a dose close to 25 times the MRHD (on the mg/m2 basis having a maternal oral dose of a hundred and twenty mg/kg/working day); nonetheless, these outcomes occurred during the presence of maternal toxicity.
Codeine has actually been noted to indicate no proof of carcinogenicity or mutagenicity in a variety of take a look at techniques, such as the micronucleus and sperm abnormality assays plus the Salmonella assay. Promethazine was nonmutagenic during the Salmonella examination technique of Ames.

Codeine Carcinogenicity scientific studies ended up conducted with codeine. Two-yr experiments in F344/N rats and B6C3F1 mice have been done to assess the carcinogenic probable of codeine. No proof of tumorigenicity was observed in male and female rats at codeine dietary doses as many as 70 and eighty mg/kg/day (somewhere around akin to 15 and twenty situations, the MRHD over a mg/m2 basis, respectively).
