In the ever-evolving landscape of healthcare, novel medications targeting specific incretin hormones (gut peptides produced after eating and which stimulate insulin secretion) continue to emerge, offering promising solutions for patients with type 2 diabetes and obesity.
Two such medications, semaglutide and tirzepatide, have gained attention for their potential to achieve significant body weight reduction.
But how do these drugs work, and how do they differ? Let’s look at mechanisms of action, benefits, possible side effects, and other patient considerations. But before we look at these medications, let’s explore them.
Tirzepatide – A Dual-Receptor Targeting Medication
Tirzepatide, is a groundbreaking medication designed to aid patients with type 2 diabetes in weight loss while lowering blood glucose levels.
By targeting both the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1) receptor agonists, tirzepatide distinguishes itself as the first medication in its class.
Mechanism of Action
Tirzepatide works by mimicking the actions of both GIP and GLP-1 receptor agonists, signaling the pancreas to reduce insulin release after food intake and instructing the liver to decrease glucose levels. These processes slow digestion, providing a prolonged feeling of fullness and improved glycemic control, contributing to weight reduction.
Semaglutide – A Single-Receptor Targeting Medication
Semaglutide, is another medication used for weight loss in addition to lifestyle changes.
Unlike tirzepatide, semaglutide targets only the GLP-1 receptor agonist, stimulating insulin secretion and slowing gastric emptying.
Additionally, studies found that semaglutide lowered the risk of cardiovascular episodes in type 2 diabetes patients.
Mechanism of Action
By mimicking the GLP-1 receptor agonist produced by the gut after meals, semaglutide helps signal your brain that you are full.
This stimulates insulin secretion, slows down gastric emptying, and influences areas of the brain responsible for satisfaction and hunger levels, contributing to weight loss.
Effectiveness of Tirzepatide and Semaglutide
Clinical trials have demonstrated the effectiveness of both tirzepatide and semaglutide in achieving significant weight loss among patients with type 2 diabetes and obesity.
Semaglutide has shown positive results in various trials, with a placebo-controlled study indicating that 63% of patients on semaglutide lost 5% or more of their body weight after one year of treatment. Another two-year trial revealed an average weight loss of 4.9kg for those using semaglutide in combination with lifestyle changes.
Tirzepatide, although a newer medication, has exhibited impressive weight loss results. In a clinical trial involving over 2500 participants, tirzepatide resulted in a weight reduction of 15-20% of starting body weight at 72 weeks, surpassing the placebo group by a significant margin.
How do Tirzepatide and Semaglutide Compare?
When comparing tirzepatide and semaglutide, the primary difference lies in their receptor targeting. Tirzepatide’s dual-target approach may contribute to its more significant weight loss results than semaglutide. However, your doctor will consider your overall health, unique needs, and weight loss goals before prescribing any weight loss medications.

In conclusion, both tirzepatide and semaglutide stand out as effective medications for weight loss in patients with type 2 diabetes and obesity.
