Study Notes
Sulfonylureas Overview
- Sulfonylureas are oral hypoglycemic agents used to manage type 2 diabetes.
- Sulfonylureas are not first-line drugs for managing type 2 diabetes due to the risk of hypoglycemia.
- Second-generation sulfonylureas are more commonly used than first-generation drugs due to their increased potency and shorter duration of action.
Mechanism of Action
- Sulfonylureas stimulate insulin release from pancreatic beta cells by:
- Binding to and blocking ATP-sensitive potassium channels in the cell membrane.
- This causes membrane depolarization, calcium influx, and insulin release.
- Insulin release by sulfonylureas is glucose-dependent:
- They are effective in lowering blood glucose levels when glucose is present.
- They pose a risk for hypoglycemia if not managed correctly.
Indications & Therapeutic Uses
- Management of type 2 diabetes to improve glycemic control.
Side Effects & Adverse Reactions
- Hypoglycemia is a common side effect due to increased insulin release. Clients need education on signs, symptoms, and monitoring.
- Cardiovascular toxicity is a concern with first-generation sulfonylureas, but studies are inconclusive.
Precautions & Contraindications
- Use with caution in clients with hepatic or renal impairment as these conditions can affect drug metabolism and excretion.
- Contraindicated in pregnancy due to the risk of neonatal hypoglycemia and potential teratogenic effects.
- Contraindicated in breastfeeding due to the risk of infant hypoglycemia.
Drug Interactions
- Sulfonylureas can interact with other hypoglycemic agents, including:
- Alcohol
- Non-selective beta-blockers
- Insulin
- This can increase the risk of hypoglycemia.
- All beta-blockers can mask hypoglycemia by blocking tachycardia and delaying awareness of decreasing blood sugar.
Dosing, Administration, & Client Teaching
- Dosing varies based on condition, severity, and client response.
- Check drug dosing guidelines for specific dosing information.
- Administration is oral, once or twice daily, depending on the specific drug and client's blood glucose control needs.
- Clients should be educated on:
- The risks of hypoglycemia
- How to monitor for and treat hypoglycemia.
- These medications are only indicated for treatment regimens if medication access or cost is an issue for clients.
Labs to Monitor
- Basic Metabolic Panel (BMP):
- Monitor blood glucose levels and kidney function.
- Hemoglobin A1c:
- Monitor the effectiveness of the treatment regimen.
Sulfonylureas: Overview
- Sulfonylureas are oral hypoglycemic agents used in the management of type 2 diabetes.
- They are not first-line drugs due to the potential for hypoglycemia.
- Second-generation sulfonylureas are more potent with a shorter duration of action than first-generation drugs.
Sulfonylurea Mechanism of Action
- Sulfonylureas stimulate insulin release from pancreatic beta cells.
- They work by blocking ATP-sensitive potassium channels, leading to membrane depolarization, calcium influx, and insulin release.
- Insulin release is glucose-dependent, meaning they effectively lower blood glucose levels when glucose is present, and can pose a risk for hypoglycemia if not managed correctly.
Sulfonylurea Indications & Therapeutic Uses
- They are used to improve glycemic control in clients with type 2 diabetes.
Sulfonylurea Side Effects & Adverse Reactions
- Hypoglycemia: A common side effect due to the stimulation of insulin release. Clients need education on signs, symptoms, and monitoring requirements.
- Cardiovascular Toxicity: A concern with only first-generation sulfonylureas, although research on this is inconclusive.
### Sulfonylurea Precautions & Contraindications
- Precautions: Use with caution in clients with hepatic or renal impairment.
-
Contraindications:
- Pregnancy: Risk of neonatal hypoglycemia and potential teratogenic effects.
- Breastfeeding: Risk of infant hypoglycemia.
### Sulfonylurea Drug Interactions
- Other hypoglycemic agents: Increased risk of hypoglycemia.
- Alcohol, non-selective beta-blockers, and insulin: Increase the risk of hypoglycemia.
- Beta-blockers: Can mask hypoglycemia by preventing tachycardia, delaying awareness of low blood sugar.
Sulfonylurea Dosing, Administration, & Client Teaching
- Dosing varies based on condition, severity, and client response.
- Administration is oral, once or twice daily.
- Clients should be educated on the risks of hypoglycemia, monitoring techniques, and how to treat it.
- Sulfonylureas are only indicated for treatment regimens if medication access or cost is an issue for clients.
Sulfonylurea Labs to Monitor
- Basic Metabolic Panel (BMP): Monitors blood glucose levels and kidney function.
- Hemoglobin A1c: Provides information on the effectiveness of the treatment regimen.
Sulfonylureas
- Sulfonylureas are oral hypoglycemic agents used in the management of type 2 diabetes.
- Sulfonylureas stimulate the release of insulin from pancreatic beta cells by blocking ATP-sensitive potassium channels in the cell membrane.

- Second-generation sulfonylureas are more commonly used due to their increased potency and shorter duration of action.
Side Effects and Adverse Reactions
- Sulfonylureas can cause hypoglycemia.
- First-generation sulfonylureas can potentially cause cardiovascular toxicity.
Precautions and Contraindications
- Use with caution in clients with hepatic or renal impairment.
- Contraindicated in pregnancy due to the risk of neonatal hypoglycemia and potential teratogenic effects.
- Contraindicated in breastfeeding clients due to the risk of infant hypoglycemia.

Dosing, Administration, & Client Teaching
- Dosing varies based on condition, severity, and client response.
- Administered orally, once or twice daily.
- Clients should regularly monitor their blood glucose levels to avoid hypoglycemia.
- Clients should be educated in recognizing the signs and symptoms of hypoglycemia and how to manage it.
