Evaluate the effect of bethanechol on blood glucose levels in euglycemic Wistar albino rats through oral glucose tolerance test

Abstract

Objective: To evaluate the effect of bethanechol on blood glucose levels in euglycemic Wistar albino rats through oral glucose tolerance test (OGTT). Materials and Methods: Twelve Wistar albino rats weighing around 150-200 g of either sex were randomly selected from the central animal facility, and were divided into two groups. The control group received distilled water (25 mL/kg body wt.) per orally, test groups received bethanechol (3.6 mg/kg/day) per orally for 5 days. On the fifth day, following overnight fasting, 1 h after drug administration in all the groups of rats OGTT was performed, by administering oral glucose in dose of 0.6 gm/kg body weight. The capillary blood glucose (CBG) levels were measured at 0 min, 60 min, and 150 min, by rat tail snipping method using glucometer (ACCUCHEK). Results: The CBG levels of the bethanechol group was less when compared to the control group at all time intervals and the difference was statistically significant. Conclusion: Bethanechol showed the hypoglycemic activity when given for 5 days orally to euglycemic albino rats through OGTT.
