The findings of a study revealed that for the highest doses, Tirzepatide led to an average weight loss of 5.7 kilograms (12.5 pounds) more than Semaglutide.
In the ever-evolving landscape of pharmaceuticals, the pursuit of effective treatments for diabetes and obesity remains a top priority. Recently, a review of groundbreaking research has unveiled the potential of Tirzepatide, marketed as Mounjaro by Eli Lilly, to surpass its blockbuster rival Semaglutide Ozempic in terms of weight loss and blood sugar control. While both drugs have made significant strides in managing type 2 diabetes and aiding in weight loss, this new study suggests that Tirzepatide might be the game-changer the medical community has been waiting for.

Tirzepatide’s impact on diabetes and obesity care
Tirzepatide, approved for treating type 2 diabetes in the United States, Europe, and recently the UK, has been steadily gaining recognition for its efficacy. Now, Eli Lilly is seeking authorization in the US for its use in obesity treatment, setting the stage for fierce competition with Novo Nordisk’s Semaglutide, known as Ozempic for diabetes and Wegovy for weight loss.
Semaglutide’s soaring popularity earlier this year on social media for its weight loss benefits created high demand, leading to sporadic supply shortages. Concerns also arose about its misuse by individuals without diabetes or obesity seeking to shed a few pounds. However, the emergence of Tirzepatide and its potential to outperform Semaglutide has sparked renewed interest in these drugs.
Ozempic’s mode of action
Ozempic, known as Semaglutide, is an injectable medication primarily designed to regulate blood glucose levels in adults with Type 2 diabetes. Additionally, it has been found to reduce the risk of heart attacks and strokes in individuals with both Type 2 diabetes and heart disease.
Although Ozempic is not officially sanctioned for weight loss, some individuals taking this medication may experience weight loss as a side effect due to its mode of action. It’s important to note that if one does not have diabetes and chooses to use Ozempic for weight loss, this usage is considered an off-label application.
Ozempic is not an insulin type or a replacement for insulin. Instead, it triggers the consumer’s pancreas to release insulin in response to the presence of glucose, typically after a meal. Ozempic relies on consumer’ body’s natural insulin production for this mechanism. Therefore, it is not employed in situations where the pancreas cannot produce insulin, such as in Type 1 diabetes.
Comparing Tirzepatide and Semaglutide
Both Tirzepatide and Semaglutide operate by mimicking the gastrointestinal hormone GLP-1, which activates receptors in the brain responsible for appetite regulation. However, Tirzepatide takes it a step further by also targeting the hormone GIP, which stimulates insulin release.
In a research study presented at a conference in Germany, Greek researchers synthesized data from 22 previous randomized control trials that separately investigated Tirzepatide and Semaglutide. Both drugs are administered as weekly injections and are designed to help individuals with type 2 diabetes manage their condition and lose weight. The collective data from these trials involved nearly 18,500 patients with type 2 diabetes, and the research compared three different doses of each drug over a minimum 12-week period.
The findings of this study revealed that for the highest doses, Tirzepatide led to an average weight loss of 5.7 kilograms (12.5 pounds) more than Semaglutide. Additionally, Tirzepatide resulted in a two percent reduction in blood sugar levels when compared to the highest dose of Semaglutide. However, it’s worth noting that the highest Tirzepatide dose was associated with increased gastrointestinal adverse events.
As the scientific community eagerly awaits more extensive research and peer-reviewed studies, the potential of Tirzepatide as a groundbreaking treatment for both type 2 diabetes and obesity cannot be denied. While Semaglutide has been a notable player in this field, the emergence of Tirzepatide showcases the continued advancements in pharmaceuticals, offering hope for those seeking effective solutions for weight management and blood sugar control.
What are the side effects of Ozempic?
Particularly when initiating Ozempic treatment, individuals may encounter gastrointestinal side effects. These side effects are similarly prevalent when the dosage is raised. Fortunately, for the majority of individuals, these effects tend to improve with time.
Common Ozempic side effects include:
- Nausea
- Vomiting
- Diarrhea
- Stomach pain
- Constipation
- Cautions and Considerations
Cautions and Considerations of the medicines
While these findings are promising, it’s crucial to emphasize that the research has not yet undergone peer review, which is a vital step in ensuring scientific rigor and accuracy. Duane Mellor, an expert in evidence-based medicine at Aston University in the UK, pointed out the need for a more comprehensive comparison between the two drugs.
Moreover, given the history of supply shortages of these medications, it is imperative that they are allocated to those with the most urgent medical needs, particularly people living with type 2 diabetes.
However, it is essential to exercise caution and ensure equitable access to these drugs for those in greatest need, given their potential impact on public health.
The upcoming Annual Meeting of the European Association for the Study of Diabetes is expected to shed further light on this promising development, with the hope that it will bring us one step closer to more effective treatments for type 2 diabetes and obesity.
