Introduction
This document provides a comprehensive comparison between two medications for type 2 diabetes management: Rybelsus and Trulicity. While both drugs are designed to control blood glucose levels, they differ in their active ingredients, administration methods, and mechanisms of action. Rybelsus contains semaglutide, a GLP-1 receptor agonist taken orally, whereas Trulicity contains dulaglutide, also a GLP-1 receptor agonist, but administered via injection. This analysis evaluates their effectiveness, safety, cost, and overall patient convenience to assist patients and healthcare professionals in making informed treatment decisions.

How Rybelsus and Trulicity Work: Mechanism of Action
Rybelsus: Contains semaglutide, a GLP-1 receptor agonist that increases insulin secretion, decreases glucagon production, and slows gastric emptying to lower blood sugar levels.
Trulicity: Contains dulaglutide, a GLP-1 receptor agonist that stimulates insulin secretion and inhibits glucagon release in response to high blood glucose levels, while also slowing gastric emptying.
