GLP-1 Agonists Overview

Overview of GLP-1 Agonists

• Definition: GLP-1 agonists are a class of drugs that mimic the glucagon-like peptide-1 (GLP-1) hormone.
• Function: They help regulate blood sugar levels and support weight loss.

Mechanism of Action

• Stimulate insulin secretion in response to food intake.
• Inhibit glucagon release from the pancreas.
• Slow gastric emptying, which reduces postprandial (after eating) blood sugar spikes.
• Enhance satiety (feeling of fullness) leading to reduced food intake.

Therapeutic Uses

• Primarily used for Type 2 diabetes management.
• Also indicated for weight management and obesity treatment.
• May improve cardiovascular outcomes in patients with diabetes.

Common GLP-1 Agonists

1. Exenatide (Byetta, Bydureon)
2. Liraglutide (Victoza, Saxenda)
3. Dulaglutide (Trulicity)
4. Semaglutide (Ozempic, Wegovy)
5. Lixisenatide (Adlyxin)

Administration

• Available as injectable formulations:
  • Daily or weekly dosing regimens (varies by specific drug).

Benefits

• Weight loss in overweight or obese patients.
• Lower risk of hypoglycemia compared to insulin or sulfonylureas.
• Positive effects on cardiovascular health.

Side Effects

• Common:
  • Nausea
  • Vomiting
  • Diarrhea
• Serious:
  • Risk of pancreatitis
  • Possible thyroid tumors (observed in animal studies)

Contraindications

• Personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2.
• History of severe gastrointestinal disease.

Monitoring

• Regular monitoring of blood glucose levels.
• Assessing renal function and potential side effects.

Patient Considerations

• Discuss lifestyle changes (diet and exercise) alongside medication.
• Educate on potential side effects and the importance of adherence to therapy.

GLP-1 Agonists

• GLP-1 agonists mimic the natural hormone glucagon-like peptide-1 (GLP-1)
• These drugs help manage blood sugar levels and support weight loss.
• They stimulate insulin release after meals, suppress glucagon production, slow down stomach emptying, and increase feelings of fullness.

Mechanism of Action

• GLP-1 agonists increase insulin secretion after eating, helping lower blood sugar.
• They reduce glucagon release from the pancreas, further contributing to lower blood sugar.
• Slowing down stomach emptying with GLP-1 agonists helps maintain stable blood sugar levels after meals.
• They enhance satiety, making you feel fuller for longer and leading to reduced food intake.

Therapeutic Applications

• Primarily used for managing type 2 diabetes.
• Also indicated for weight management and treating obesity.
• May improve cardiovascular outcomes in patients with diabetes.

• Lixisenatide (Adlyxin)

Administration

• Available as injectable formulations.
• Dosing regimens vary with each drug, ranging from daily to weekly injections.

Benefits

• Support weight loss in overweight or obese patients.
• Lower the risk of low blood sugar compared to insulin or sulfonylureas.
• May have positive effects on cardiovascular health.

Side Effects

• Common:

  • Nausea
  • Vomiting
  • Diarrhea

• Serious:

  • Risk of pancreatitis
  • Possible thyroid tumors (observed in animal studies)

Contraindications

• Personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia type 2.
• History of severe gastrointestinal disease.

Monitoring

• Regular monitoring of blood glucose levels is essential.
• Closely monitor kidney function and be aware of potential side effects.
• Lifestyle modifications (diet and exercise) should be discussed with patients alongside medication.
• Educate patients about potential side effects and the importance of adherence to treatment..
