The antidiabetic activity of the new composition “Thigliben” on the experimental dexamethasone diabetes mellitus model in rats
Keywords:diabetes mellitus type 2, experimental pharmacology, complex hypoglycemic drugs, glibenclamide
Being a metabolic disease with long-term hyperglycemia, diabetes mellitus significantly increases the risk of microvascular and macrovascular diseases and organ pathologies, respectively. The creation of the new composition “Thigliben”, which allows not only qualitatively controlling diabetic hyperglycemia, but also providing a preventive and/or therapeutic effect on the development of diabetic polyneuropathy was pathogenetically reasonable.
Aim. To study the antidiabetic activity of “Thigliben” on the experimental dexamethasone diabetes mellitus in rats.
Materials and methods. The pharmacological study of the antidiabetic activity of the new composition “Thigliben” in the dose of 4 mg/kg was performed. The experimental studies were conducted on a standard model of the experimental dexamethasone type 2 diabetes mellitus in rats. Glibenclamide in the dose of 0.6 mg/kg (corresponds to an average human daily dose of 10 mg) was selected as the reference drug.
Results. It was found that by its effects on the carbohydrate and lipid metabolism the new composition “Thigliben” was similar to the reference drug glibenclamide administered in a higher dose. By the antioxidant activity this composition exceeded the effect of the reference drug, provided that normalization of the TBA-RS level in the liver homogenate was significant. The new composition “Thigliben” normalized all the parameters of the cerebral energy metabolism studied relative to the control pathology group and its efficiency was significantly higher than that of the reference drug glibenclamide. The new composition “Thigliben” increased the content of ATP by 109 % compared to the control pathology group, in contrast to 68 % on the background of glibenclamide; restored the activity of citrate synthase by 65 %, succinate dehydrogenase by 134 %, and pyruvate dehydrogenase by 61 % relative to the control pathology group. For glibenclamide the change in these indicators was 28 %, 50 %, and 22 %, respectively. The results obtained suggest that the metabolic effect of “Thigliben” composition is significantly more effective than that of the reference drug glibenclamide.
Conclusions. The new composition “Thigliben” is a promising antidiabetic drug with a pronounced hypolipidemic, antioxidant effect and the ability to restore energy deficiency; it is its significant advantage over the standard treatment regimens, including the average therapeutic doses of glibenclamide.
