Introduction: Nimesulide is a non-steroidal antiinfflamatory drug associated with hepatotoxicity. Nevertheless, there have few published controlled studies with animals. Objec - tive: Determine whether the administration of therapeutic doses of nimesulide during differents periods alters hepatic function in male and female rats. Materials and me - thods: Forty Wistar rats were classified into 4 groups of 10 rats each. Group I received 0,1 ml of saline for 7 days, whe reas the animals from groups II, III and IV were treated with Ni mesulide (3 mg/kg) during 7, 21 and 35 days, respectively. It has determined serum levels of bilirubin, alkaline phos pha tase and transaminases. Results: Alanino-amino-transferase (ALT) enzyme was increased in males (p<0.01) and females (p<0.02) from groups III and IV in com parison with the control group. Alkalin phosphate increased in males from groups II and IV in comparison with the females from these same groups (p< 0.05). Direct and total bilirubins decreased in group IV females (p< 0.03) in comparison with the control group. Conclusions: The administration of therapeutic doses of nimesulide affects hepatic function on Wistar rats.
