Although the precise mechanisms by which metformin exerts its antihyperglycemic effects are not entirely certain, they are largely attributed to a reduction in hepatic gluconeogenesis, a decrease in intestinal glucose absorption, and an increase in peripheral tissue sensitivity to insulin.1,4,5 To a lesser degree, metformin may also increase glucose uptake by skeletal muscles.6, Although experience with metformin in animals is limited, studies have shown that the general pharmacokinetics of metformin in cats is similar to that reported in people.2,7 In people, metformin is absorbed slowly from the gastrointestinal (GI) tract, with peak plasma concentrations reached within one to three hours after ingestion. When refining the classifications within MALA, Lalau and others take metformin concentration and concurrent disease processes into account 14.
