DOI: 10.1515/amma-2015-0072

Aim: the purpose of the present study was to determine the effects of amisulpride at different doses on body weight, glucidic and lipidic metabolism.
Material and method: Thirty-six white Wistar rats were treated daily for 9 weeks with amisulpride 1mg/kg and 10mg/kg body weight. Another group received distilled water and served as control group. At the end of the treatment period blood samples were collected and the follow biochemical parameters were determined: serum cholesterol, triglycerides, blood glucose, GOT, GPT. Body weight gain was also assessed weekly.
Results: After treatment with amisulpride in doses of 1mg/kg and 10 mg/kg for a period of nine weeks, weight gains were recorded for both groups compared with the initial weight and the control group. Blood glucose concentrations in the group treated with 1 mg amisulpride/kg body weight were significantly increased (p<0.05 vs control group), but in the group treated with 10 mg/kg body weight glucose levels were not statistically significant increased compared to controls. Other biochemical parameters (cholesterol, triglycerides, GOT, GPT) showed no statistically significant differences compared to control group.
Conclusions: amisulpride administered over a period of 9 weeks, in doses of 1mg/kg and 10mg/kg showed a slight increase of body weight regardless of gender, increased blood glucose only when was administered in the low dose, and does not affect lipid metabolism, even though decreased cholesterol and triglycerides levels. This results highlight a real benefit of treatment with amisulpride, comparatively with other athypical antipsychotics.
