Toxicology, carcinogenicity, and teratogenicity of some orally administered retinoids

This paper is a review of the acute, subchronic, and chronic toxicity, mutagenicity, carcinogenicity, and teratogenicity of vitamin A, tretinoin (all-trans-retinoic acid), isotretinoin (13-cis-retinoic acid), and etretinate. The results of in vitro mutagenicity testing of the retinoids are also presented. In addition to teratogenesis studies, experiments designed to evaluate the effects of the retinoids on fertility and reproductive performance and on perinatal and postnatal development are also described.
