NURS 615 Exam IV/ 81 Q&A/ Already Graded A+/ . Terms like: How does metformin work? - Answer: Decreases hyperglycemia by decreasing hepatic glucose production called hepatic gluconeogenesis. The average person with type 2 diabetes has three times the rate of gluconeogenesis, metformin treatment reduces this by over 1/3rd. The molecular mechanism of metformin isn't completely understood. In addition to suppressing hepatic glucose production, metformin increases insulin sensitivity, enhance...
