Dulaglutide. Weekly GLP-1 receptor agonist for type 2 diabetes with proven cardiovascular benefit.

How it works. Activates GLP-1 receptors: increases glucose-dependent insulin release, lowers glucagon, slows stomach emptying and reduces appetite.

What the research supports. 3 graded claims. Strongest: Lowers HbA1c in type 2 diabetes (strong).

Hormonal impact. Effects on Insulin, Glucagon.

Side effects and interactions. 2 medication interactions listed. Serious: Pancreatitis.

Stacking. Avoid combining with Other GLP-1 drugs.

Common forms. Available as Weekly injection pen.

Community. Experiences from people who have tried Dulaglutide. Anecdotes are not medical advice.

No single structure

What it is

A GLP-1 analog fused to an antibody fragment so one injection lasts a week. The REWIND trial showed fewer heart attacks, strokes and cardiovascular deaths.

Also called

Trulicity

How it works

Activates GLP-1 receptors: increases glucose-dependent insulin release, lowers glucagon, slows stomach emptying and reduces appetite.

Pathways

  • GLP-1 receptor agonism
  • Glucose-dependent insulin release
  • Slower gastric emptying

Effects

  • ↓Blood glucose decreases
  • ↓Appetite decreases

Reduces major cardiovascular events (REWIND trial)strong
Modest weight lossmoderate

Strong: consistent results across large trials or meta-analyses. Moderate: several trials, mostly positive. Limited: small or mixed studies. Preclinical: animal or cell research only.
