List of GLP-1 Agonists

GLP-1 receptor agonists have emerged as a breakthrough in the management of type 2 diabetes and obesity. These medications work by mimicking the action of the glucagon-like peptide-1 (GLP-1) hormone, promoting insulin secretion, reducing appetite, and improving glycemic control. Below is a detailed list of GLP-1 receptor agonists, their applications, and key characteristics.

1. Semaglutide

• Indications:
  • Ozempic: Type 2 diabetes
  • Wegovy: Chronic weight management
  • Rybelsus: Type 2 diabetes (oral form)
• Key Features:
  • Administered weekly (Ozempic and Wegovy)
  • Proven significant weight loss benefits with Wegovy
  • Available in oral form (Rybelsus), offering convenience for some patients

2. Liraglutide

• Brand Names: Victoza, Saxenda
• Indications:
  • Victoza: Type 2 diabetes and reducing cardiovascular risks
  • Saxenda: Weight management

• Key Features:
  • Administered once daily
  • Often used in combination with basal insulin

7. Tirzepatide (Dual GIP/GLP-1 Receptor Agonist)

• Brand Name: Mounjaro
• Indications: Type 2 diabetes (with ongoing studies for weight management)
• Key Features:
  • Administered weekly
  • Targets both GLP-1 and GIP receptors, offering enhanced glycemic and weight-loss benefits

8. Efpeglenatide

• Brand Name: Not commercially available in all markets
• Indications: Type 2 diabetes
• Key Features:
  • Administered weekly
  • Currently under investigation for broader applications

How GLP-1 Agonists Work

GLP-1 agonists bind to GLP-1 receptors in the pancreas and brain, triggering:

• Increased insulin secretion in response to meals
• Reduced glucagon release, lowering blood sugar levels
• Slowed gastric emptying, prolonging feelings of fullness
• Appetite suppression, aiding in weight management

Choosing the Right GLP-1 Agonist

Selecting the appropriate GLP-1 agonist depends on individual needs, such as:

• Primary goal (e.g., weight loss vs. blood sugar control)
• Frequency of dosing (daily vs. weekly)
• Preference for injection vs. oral administration
• Insurance coverage and cost

Conclusion

GLP-1 receptor agonists represent a powerful tool for managing type 2 diabetes and obesity. With options ranging from daily injections to weekly treatments and even oral formulations, patients and healthcare providers can tailor therapies to meet individual needs. As research continues, these medications are expected to play an even greater role in metabolic health.
