Information about Glucophage
Liver safety of Glucophage
Metformin has not been linked to serum enzyme elevations during therapy and is an exceeding rare cause of idiosyncratic clinically apparent acute liver injury.
Mechanism of action of Glucophage
Metformin (met for' min) is a biguanine and acts as an insulin sensitizing agent, probably through activation of adenosine monophosphate dependent (AMP) kinase in liver and muscle tissue. Metformin is often associated with weight loss making it a preferred, first line agent for management of overweight patients with type 2 diabetes. Initial concerns about the possibility that metformin (like the related biguanine phenformin) could induce lactic acidosis have been largely resolved, although the agent is contraindicated in patients with renal dysfunction because of this reason and should be used with caution in patients with significant liver disease.
