[Renal function and histologic studies in rats treated by floctafenin (author's transl)].
The nephrotoxic action of floctafenin has been studied in rats. When administered orally at 20 or 50 mg/kg/day for 20 or 50 days, this analgesic agent had no effect on the renal function, either in intact rats or in animal with reduced renal parenchyma. There is no histological change in the kidneys of the treated animals except some focal dilatations of the distal tubules. The tubular alterations were more important in treated and untreated rats with nephronic reduction. The whole body autoradiographic studies of rats treated with 14C floctafenin showed that liver and kidney accumulate radioactivity, and that the intake of radiolabeled compounds is twice higher in renal cortex than in medulla. This study suggests that the toxicity of floctafenin for the rat kidney is very low or none.
