THERAPEUTIC CLASSIFICATION
Anti hyperglycemic Agent
ACTIONS AND CLINICAL PHARMACOLOGY
Metformin is a biguanide derivative producing an antihyperglycemic
effect which can only be
observed in man or in the diabetic animal and only when there is
insulin secretion. Metformin, at
therapeutic doses, does not cause hypoglycemia when used alone in man
or in the nondiabetic
animal, except when using a near lethal dose. Metformin has no effects
on the pancreatic beta cells.
The mode of action of metformin is not fully understood. It has been
postulated that metformin
might potentiate the effect of insulin or that it might enhance the
effect of insulin on peripheral
receptor sites. This increased sensitivity seems to follow an increase
in the number of insulin
receptors on cell surface membranes.
Metformin absorption is relatively slow and may extend over about 6
hours. The drug is excreted in
urine at a high renal clearance rate of about 450 mL/min. The initial
elimination of metformin is
rapid with a half-life varying between 1.7 and 3 hours. The terminal
elimination phase accounting
for about 4 to 5% of the absorbed dose is slow with a half-life
between 9 and 17 hours. Metformin is
not metabolized. Its main sites of concentration are the intestinal
mucosa and the salivary glands.
The plasma concentration at steady state ranges about 1 to 2 µg/mL.
Certain drugs may potentiate
the effects of metformin (see
PRECAUTIONS).
