Which oral diabetes drugs directly stimulate insulin secretion? How does this differentiate them
from other oral antidiabetic drugs?
Sulfonylureas (-ide)
- Glipizide (Glucotrol)
- Glyburide (DiaBeta, Micronase)
- Glimepiride (Amaryl)
Meglitinides (glinides)
- Repaglinide (Prandin)
- Nateglinide (Starlix)
They have a greater risk of hypoglycemia than other oral diabetic agents, since the others only
increase glucose uptake or increase insulin sensitivity (not the amount of insulin produced)
What medications are Biguanides?
- Metformin (Glucophage)
Biguanides mechanism of action
- Decreases glucose production by the liver
- Sensitizes insulin receptors in tissues
- Reduces absorption of glucose in GI tract

What medications are Sulfonylureas?
Tolbuatmide (Orinase)
Glyburide (DiaBeta, Micronase)

Sulfonylureas mechanism of action
- Promotes insulin secretion from pancreatic islets
- Increase tissue sensitivity to insulin over time
Sulfonylureas = Glipizide, Glyburide, Glimepiride
