PHARMACOLOGICAL ACTION
PHARMACODYNAMIC PROPERTIES_ _
Metformin
is
a
biguanide
with
anti-hyperglycaemic
effects,
lowering
both
basal
and
postprandial plasma glucose. It does not stimulate insulin secretion
and therefore does not
produce hypoglycaemia.
Metformin may act _via_ three mechanisms:
-
reduction of hepatic glucose production by inhibiting gluconeogenesis
and
glycogenolysis;
-
in muscle, by increasing glucose sensitivity, improving peripheral
glucose uptake and
utilisation; and
-
delay of intestinal glucose absorption.
Metformin stimulates intracellular glycogen synthesis by acting on
glycogen synthase.
Metformin increases the transport capacity of all types of membrane
glucose transporters.
