Analgesic, anti-inflammatory and hypouricemic effects of GT1 film-coated tablets on experimental animals

Abstract

Aim: To evaluate pain relief, anti-inflammatory and hypouricemic effects of GT1 tablets on experimental animals.
 Method: GT1 at the doses of 22.32 g/kg/day and 66.96 g/kg/day were evaluated for its analgesic effect in three models (hot plate, pain threshold, and acetic acid-induced writhing), its chronic anti-inflammatory effect in the granulomatous reaction model, and its hypouricemic effect in potassium oxonate-induced hyperuricemic mice. Acute anti-inflammatory effects of GT1 at the doses of 11.16 g/kg/day and 33.48 g/kg/day were evaluated in rats with two models: carrageenin-induced paw edema and peritonitis.
 Results: GT1 prolonged the temperature reaction time on the hot plate (22.73 s and 20.37 s at both doses of 22.32 g/kg and 66.96 g/kg, respectively, compared to 16.96 s in control group), reduced the number of acid acetic-induced writhing effects, decreased the weight of granulomas, and decreased the level of acid uric in blood and urine (p < 0.05). GT1 caused a significant reduction in paw edema after subplantar injection of carrageenan in rats (p < 0.05). Moreover, there was a substantial decline of GT1 at the dose of 11.16 g/kg/day in terms of the volume and the quantity of protein in the inflammation fluid of the peritonitis model (p < 0.05).
 Conclusion: GT1 at both doses of 11.16 g/kg/day and 33.48 g/kg/day posed acute anti-inflammatory effects on rats. GT1 at both doses of 22.32 g/kg/day and 66.96 g/kg/day exerted analgesic, chronic anti-inflammatory and hypouricemic effects on mice.
