DESCRIPTION
Metformin hydrochloride is a white, crystalline powder which is almost
odourless and hygroscopic. It is
freely soluble in water, slightly soluble in ethanol (96%) and
practically insoluble in chloroform and in
ether.
PHARMACOLOGY
Metformin is an oral biguanide hypoglycaemic agent. It causes an
increased peripheral uptake of
glucose by increasing the biological efficiency of available exogenous
or endogenous insulin.
The mode of action of metformin may be linked to an increase of
insulin sensitivity. It does not
stimulate insulin release but does require the presence of insulin to
exert its anti-hyperglycaemic
effect. Possible mechanisms of action include inhibition of
gluconeogenesis in the liver, delay in
glucose absorption from the gastrointestinal tract and an increase in
peripheral uptake of glucose.
Metformin has an antiketogenic activity which is comparable, though
somewhat inferior, to insulin
itself. Metformin lowers both basal and post-prandial blood glucose in
diabetic patients but does not
cause hypoglycaemia in either diabetics or normal individuals.
PHARMACOKINETICS
Absorption
After
oral
administration,
metformin
hydrochloride
is
absorbed
along
the
entire
gastrointestinal
mucosa. Studies using single oral doses of metformin tablets indicate
that there is a lack of dose
proportionality with increasing doses, which is due to decreased
absorption of meformin rather than an
increase in elimination. After oral administration, metformin
absorption is saturable and incomplete. It
is assumed that the pharmacokinetics of metformin absorption are
non-linear.
At usual clinical doses and dosing schedules of metfor
