Mild analgesics have been associated with antiandrogenic effects, but there are no such studies on dipyrone, despite its high prevalence of use in many countries. We examined the production of steroid hormones in human H295R cells after exposure to dipyrone and two metabolites, 4-Methylaminoantipyrine (MAA) and 4-Aminoantipyrine (AA), as well as fetal testicular testosterone production in rats following maternal dipyrone exposure. Androgen agonistic/antagonistic effects were examined in vitro for dipyrone and its metabolites in the Yeast Androgen Screen (YAS) assay and in vivo for dipyrone through the Hershberger assay. In vitro we tested dipyrone, MAA, and AA (0.1-1000 μM) while in vivo we used dipyrone (50, 100, 200 mg/kg/day). In the H295R assay, dipyrone, MAA and AA reduced the production of androgens and corticosteroids. Testosterone was reduced at concentrations 4-13 times higher than the maximum plasma concentrations reported in humans for MAA and AA. No effects were observed in the fetal testosterone production assay. In the YAS and Hershberger assays, no androgen agonistic/antagonistic activities were observed. These results indicate that dipyrone and its metabolites do not interact with the androgen receptor, but have the potential to inhibit steroidogenesis, however only at concentrations that are not relevant under normal medical use.
