Historical overview shows metformin’s efficacy in managing type 2 diabetes in overweight patients, highlighting its mechanisms and potential side effects.
Key Points
Metformin is the most widely used oral drug for managing type 2 diabetes globally, with unique mechanisms for glucose absorption.
It reduces glucose absorption and enhances intestinal glucose excretion, improving metabolic control in overweight type 2 diabetic patients.
All biguanides, including metformin, may lead to significant gastrointestinal side effects, which can limit patient adherence to therapy.
Chronic dehydration and vitamin B12 deficiency are long-term side effects associated with biguanide treatments like metformin.
