The Claim

In patients with type 2 diabetes and coronary artery disease, the improvement in disposition index (DI) induced by liraglutide is entirely mediated by increased first-phase insulin secretion (AIRg), with no contribution from changes in insulin sensitivity (Si) or glucose effectiveness (Sg), indicating a direct beta-cell effect.

How it works
1 study reviewed
In plain English

In patients with type 2 diabetes and coronary artery disease, liraglutide improves the disposition index solely by increasing the initial burst of insulin release from beta cells, without altering how the body responds to insulin or how glucose is processed independently of insulin.

See the scientific wording

The improvement in disposition index (DI) from liraglutide in patients with type 2 diabetes and coronary artery disease is entirely mediated by increased first-phase insulin secretion (AIRg), with no contribution from changes in insulin sensitivity (Si) or glucose effectiveness (Sg), indicating a direct beta-cell effect.

Why this might work

Liraglutide binds to receptors on insulin-producing cells in the pancreas, which triggers a chain of signals inside the cells that causes them to release more insulin immediately after eating. This increased insulin release improves blood sugar control without changing how the body uses insulin or clears sugar on its own.

  1. Study: Liraglutide effects on beta‐cell, insulin sensitivity and glucose effectiveness in patients with stable coronary artery disease and newly diagnosed type 2 diabetes

    The study found that liraglutide helps the pancreas release more insulin right after eating, which improves blood sugar control — but it doesn’t make the body better at using insulin or clearing sugar on its own. So, the benefit comes only from the pancreas working better.
