CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Metformin is an antihyperglycemic agent which improves glucose
tolerance in patients
with type 2 diabetes, lowering both basal and postprandial plasma
glucose. Its
pharmacologic mechanisms of action are different from other classes of
oral
antihyperglycemic agents. Metformin decreases hepatic glucose
production, decreases
intestinal absorption of glucose, and improves insulin sensitivity by
increasing peripheral
glucose uptake and utilization. Unlike sulfonylureas, metformin does
not produce
hypoglycemia in either patients with type 2 diabetes or normal
subjects (except in special
circumstances, see PRECAUTIONS) and does not cause hyperinsulinemia.
With
metformin therapy, insulin secretion remains unchanged while fasting
insulin levels and
day-long plasma insulin response may actually decrease.
