How do sulphonylureas work? Sulphonylureas are insulin secretagogues, which means they work by causing the body to secrete insulin. Another class of diabetes drugs which works in this way is the prandial glucose regulators class.
What is the mechanism of action of Sulfonylureas?
These drugs exert their hypoglycaemic effects by stimulating insulin secretion from the pancreatic beta-cell. Their primary mechanism of action is to close ATP-sensitive K-channels in the beta-cell plasma membrane, and so initiate a chain of events which results in insulin release.
How do the Sulfonylureas work do they produce hypoglycemia?
Sulfonylureas act mainly by increasing the release of insulin from the pancreatic β-cells in response to stimulation by glucose (see Fig. 40.1). They bind to the sulfonylurea receptor SUR1, which closes the KATP channel in the β-cell membrane.
