Analgesico esteroideo definicion

Introducción: El nimesulide es un analgésico antiinflamatorio no esteroideo, asociado en reportes de casos clínicos con hepatotoxicidad. Sin embargo, se han publicado pocos estudios controlados en animales. Objetivo: Determinar si la administración de dosis terapéuticas de nimesulide, durante diferentes periodos, altera el funcionalismo hepático en ratas Wistar machos y hembras. Materiales y métodos: Cuarenta ratas Wistar fueron distribuidas en 4 grupos de 10 cada uno (5 hembras y 5 machos). Grupo I (control): recibió mL de solución salina durante 7 días, los animales de los grupos II, III y IV fueron tratados con nimesulide (3 mg/kg) durante 7, 21 y 35 días, respectivamente. Se determinaron niveles séricos de bilirrubina, fosfatasa alcalina y transaminasas. Resultados: La actividad de la enzima alanino-amino-transferasa (ALT) aumentó en machos (p< ) y hembras (p < ) de los grupos III y IV respecto a los controles. En los machos de los grupos II y IV aumentó la fosfatasa alcalina en comparación con las hembras de los mismos grupos (p < ). Las bilirrubinas di - recta y total disminuyeron en las hembras del grupo IV respecto al control (p < ). Conclusiones: Los resultados sugieren que a dosis terapéuticas el nimesulide altera el funcionalismo hepático en ratas Wistar. 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

Abstract: Aim: To evaluate the effectiveness of prophylaxis with single-dose analgesic clonixinate lysine (CL 125 mg) in patients undergoing tooth extraction. Methods: A double-blind randomized placebo-controlled trial. Were included in the study patients ASA I and II with dental extraction indication in the city of Valdivia, Chile in October 2012. Were randomly assigned in two groups: the treatment group received a doses of 125mg of CL fifteen minutes before the surgery, and a control group who received placebo. Both groups used a CL as a rescue analgesic. Using a survey, patients reported the degree of pain via a visual analog scale (VAS) during the first day, at 24 and 48 hours after surgery. In addition, registered the number of CL capsules consumed as a ransom for 3 days after the surgery. We compared the analgesic effect observed in (VAS) and the number of additional analgesic consumption between the two groups using  t-test (p <0,05). Results: Fifty-four patients were operated and there was no statistically significant difference between the pain scores between the two groups. Premedication patients reported the use of equal number of rescue capsules comparing with the control group. Conclusion: CL analgesic prophylaxis proved no more effective in reducing pain after tooth extraction when comparing to the use of placebo in a postoperative doses.
