| Normal distrib 34% over and under mean
57
sulphonureas
work by increasing beta cell sensitivity to glucose thus increasing insulin release at a given plasma glucose concentration. This leads directly to a reduction in hepatic glucose production and indirectly, via a lowering of plasma glucose concentration, to decreased peripheral insulin resistance
can cause weight gain and hypoglycaemia

main mechanism is reducign hepatic glucose production
| GI disturbance common, also lactic acidosis serious SE.
59
alpha-glucosidase inhibitors e.g. acarbose

* incretin hormones - for example glucagon-dependent insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1) - these hormones are secreted by specialised enteroendocrine cells in response to a meal. The incretin hormones promote insulin secretion and inhibit glucagon secretion when blood glucose is high; when blood glucose is low then insulin secretion is inhibited and glucagon secretion is promoted
