Mechanism & Pharmacology

Understanding how Glucophage XR functions can demystify its role in managing diabetes. This medication is primarily used to lower blood sugar levels in adults with type 2 diabetes.

Simplified explanation

Glucophage XR operates by enhancing the body's sensitivity to insulin, a hormone that regulates blood sugar. It decreases glucose production in the liver and helps improve how effectively the body absorbs glucose from food. By doing so, it supports more stable blood sugar levels throughout the day, promoting overall health in individuals managing diabetes.

Clinical terms

This antihyperglycemic agent belongs to the biguanide class, specifically targeting glucose metabolism. In clinical terms, it decreases hepatic glucose production while increasing peripheral glucose uptake and utilization, ultimately improving glycemic control in patients. Health Canada has recognized its efficacy and safety for management in individuals with type 2 diabetes.

Indications & Off-Label Uses in Canada

While Glucophage XR is primarily utilized for managing blood glucose levels in diabetes, it may have other applications as well.

Approved indications
