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.
