Brand:

  • Trulicity

GLP-1 Receptor Agonists Overview

Mechanism of Action

Dulaglutide activates the GLP-1 receptor.

Effects:

  • Increases glucose-dependent insulin secretion
  • Decreases glucagon secretion
  • Slows gastric emptying
  • Increases satiety
  • Promotes weight loss

Net clinical effects:

  • Decreases HbA1c
  • Reduces body weight
  • Reduces major adverse cardiovascular events

Low hypoglycemia risk unless combined with insulin or sulfonylureas.

Indications

Type 2 Diabetes Mellitus

  • Glycemic control
  • Cardiovascular risk reduction in high-risk patients

Atherosclerotic Cardiovascular Disease (ASCVD) ★

Dulaglutide reduces:

  • Myocardial infarction
  • Stroke
  • Cardiovascular death

Particularly beneficial in patients with established ASCVD or multiple risk factors.

Cardiovascular Modules

Major Trial

REWIND Trial:

  • Reduced major adverse cardiovascular events
  • Included many patients without established ASCVD
  • Demonstrated strong primary prevention benefit

Dosing

  • Once-weekly subcutaneous injection
  • No oral formulation
  • Gradual dose escalation improves tolerability

Adverse Effects

Common:

  • Nausea
  • Vomiting
  • Diarrhea
  • Early satiety

Dulaglutide vs Other GLP-1 Agents

Exenatide

  • Shorter-acting formulations available

Liraglutide

  • Daily injection
  • Strong ASCVD data (LEADER trial)

Semaglutide

  • Greater weight loss
  • Oral option available

Dulaglutide:

  • Weekly dosing
  • Strong primary prevention data
  • Well tolerated

GLP-1 vs SGLT2

Dulaglutide:

  • Strong ASCVD reduction
  • Modest weight loss
  • Minimal heart failure benefit

SGLT2 Inhibitors:

  • Strong heart failure benefit
  • Strong renal protection

Clinical Pearls

  • Weekly injection
  • Proven ASCVD benefit
  • Good primary prevention data
  • Low hypoglycemia risk
  • Not primary heart failure therapy
