tolbutamide
insulin secretagogues - sulfonylurease - first generation
sulfa drug (all secretagogues are sulfas)
- MOA: activate residual b cells to release insulin by binding and activating SUR1
- SUR1 (sulfonylurea receptor 1) = subunit of K/ATP channel
- Activates the channel = similar to feed state - they block the K channel that closes when there is glucose around = more insulin secretion (cell thinks there is a ton of glucose around)
- May decrease hepatic clearance of insulin; decrease serum glucagon by stimulating somatostatin release
- SUR1 (sulfonylurea receptor 1) = subunit of K/ATP channel
- Contraindications
- Type 1 DM - there are no cells to secrete insulin so this wont do anything
- Preganancy
- Lactation
- Significant hepatic or renal insufficiency
