Pharmacological action:

Metformin is a biguanide with antihyperglycaemic effects, lowering both basal and postprandial plasma glucose. It does not stimulate insulin secretion and therefore does not produce
hypoglycemia.

It may act via 3 mechanisms:
(1) Reduction of hepatic glucose production by inhibiting gluconeogenesis and glycogenolysis
(2) In muscle, by increasing insulin sensitivity, improving peripheral glucose uptake and utilization
(3) And delay of intestinal glucose absorption.
Metformin stimulates intracellular glycogen synthesis by acting on glycogen synthase. It increase the transport capacity of all types of membrane glucose transporters (GLUT).
