DESCRIPTION
Metformin hydrochloride tablets are oral antihyperglycemic drugs used
in the management of type 2
diabetes. Metformin hydrochloride (_N,N_-dimethylimidodicarbonimidic
diamide hydrochloride) is not
chemically or pharmacologically related to any other classes of oral
antihyperglycemic agents. The
structural formula is as shown:
Metformin hydrochloride is a white to off-white crystalline compound
with a molecular formula of
C H N • HCl and a molecular weight of 165.63. Metformin
hydrochloride is freely soluble in water
and is practically insoluble in acetone, ether, and chloroform. The pK
of metformin is 12.4. The pH of
a 1% aqueous solution of metformin hydrochloride is 6.68.
Metformin hydrochloride tablets, for oral administration, contain 500
mg, 850 mg, or 1000 mg of
metformin hydrochloride. Each tablet contains the inactive ingredients
carnauba wax, crospovidone,
hypromellose, magnesium stearate, polydextrose, polyethylene glycol,
povidone, pregelatinized starch,
titanium dioxide, and triacetin.
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.
