Mechanism & Pharmacology

Metformin plays a pivotal role in managing type 2 diabetes by significantly improving insulin sensitivity. It operates primarily by decreasing hepatic glucose production, which is crucial for controlling blood sugar levels. In simpler terms, it helps the body use insulin more effectively while also reducing the amount of glucose produced by the liver.

Known as a biguanide antihyperglycemic, metformin is recognised in Health Canada's approved monographs for its efficacy in enhancing glycaemic control among those diagnosed with type 2 diabetes.

Indications & Off-Label Uses in Canada

The primary indication for metformin, specifically under the Drug Identification Number (DIN) for metformin, is to manage type 2 diabetes. When prescribed, this customary treatment aims to help control and stabilise blood glucose levels.

Interestingly, healthcare practitioners also utilise metformin off-label for conditions such as polycystic ovary syndrome (PCOS), showcasing its versatility beyond conventional diabetes management.

Key Clinical Findings

Recent studies, both in Canada and internationally from 2022 to 2025, showcase the effectiveness of metformin in providing long-term glycaemic control with minimal side effects. These clinical trials have reinforced its position as a cornerstone in the management of type 2 diabetes.

Health Canada remains vigilant in monitoring the safety profile of metformin, regularly assessing any adverse reactions or efficacy concerns that may arise, ensuring that patient safety is always a priority.

Alternatives Matrix

For those exploring alternatives, several comparable medications are available in Canada. Notably, Metformin Teva XR and sitagliptin (marketed as Januvia) are common options.

When considering alternatives, a pros and cons checklist can aid patients in comparing Glucophage XR with other oral antihyperglycemics. This way, patients can make an informed choice tailored to their needs.
