Final answer:
Thiazolidinediones, like pioglitazone, aid in type 2 diabetes management by increasing insulin sensitivity in peripheral tissues and reducing hepatic glucose production.
Step-by-step explanation:
Thiazolidinediones (TZDs), such as pioglitazone, exert their glucose-lowering effect in type 2 diabetic patients through several mechanisms. One of the primary actions is to improve insulin sensitivity in peripheral tissues, allowing more glucose to be taken up from the bloodstream. Additionally, they reduce hepatic gluconeogenesis, which means they inhibit the enzymes of glucose production in the liver. Together, these effects lower the blood glucose levels, providing a hypoglycemic effect beneficial in the management of type 2 diabetes.
