Drug Action: How Sulphonylurea Drugs Work

Sulphonylurea drugs are used to treat type 2 diabetes. In this type of diabetes, body tissues have reduced sensitivity to insulin. Sulphonylurea drugs stimulate cells in the pancreas to secrete more insulin to compensate for the reduced sensitivity.

Before drug

The amount of insulin made by the insulin-secreting cells in the pancreas is not sufficient for the body’s needs.

After drug

The sulphonylurea drug acts on the insulin-producing cells, stimulating them to increase production of insulin.
