title: The inhibitory effect of enfenamic acid (Tromaril) on hepatic gluconeogenesis in Swiss albino mice.
abstract: Enfenamic acid, a new non-steroidal anti-inflammatory drug was studied for its effect on hepatic gluconeogenesis and some of the enzymes involved in this process in mice. Incubation of liver cells in the presence of 1.0 mM enfenamic acid inhibited the output of glucose. And also the in vitro addition of various concentrations of enfenamic acid (0.25 to 3.0 mM) to the tissue extracts of liver inhibited the activities of important gluconeogenic enzymes such as pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK) and fructose 1,6-diphosphatase (FDPase). The oral and intraperitoneal administrations of the drug for 15 and 3 days respectively, exhibited significant decrease in the hepatic PC, PEPCK and FDPase. These findings indicated that the impairment of gluconeogenesis might be due to the inactivation of the enzymes by the drug.
