Mounjaro (Tirzepatide) is an innovative medication that is gaining attention for its impressive weight loss effects, especially when compared to Semaglutide. Both drugs are part of the same GLP-1 receptor agonist class, but tirzepatide offers a dual mechanism of action by acting on both GLP-1 and GIP receptors, making it a more powerful tool in managing weight and blood sugar levels. In this comprehensive article, we will explore the benefits, differences, availability, and effectiveness of tirzepatide in comparison to semaglutide, particularly in the context of Thailand, and delve into clinical trial results and FDA approvals.

1. What is Mounjaro (Tirzepatide)?

Eli Lilly developed Tirzepatide under the brand name Mounjaro. Designed primarily for people with type 2 diabetes, Tirzepatide is a once-weekly injectable medication that is also gaining significant attention for its potential in treating obesity. Similar to semaglutide, tirzepatide is unique in that it targets both the GLP-1 receptor and the GIP (glucose-dependent insulinotropic polypeptide) receptor.

How Does Mounjaro Work?

Mounjaro works by enhancing the body’s insulin secretion while lowering blood sugar and suppressing appetite. Mounjaro exerts a dual action by stimulating both GLP-1 and GIP receptors.

  • GLP-1 receptor agonists help reduce appetite, slow gastric emptying, and enhance insulin secretion.
  • GIP receptor agonists complement the GLP-1 effect, improving insulin sensitivity and providing more potent weight loss effects.

The dual-action approach is what makes Tirzepatide a more promising drug for weight loss compared to Semaglutide, which only targets GLP-1 receptors.

2. Mounjaro vs. Semaglutide: How Do They Compare?

Mechanism of Action

Both Mounjaro and Semaglutide are GLP-1 receptor agonists, which means they work by mimicking the hormone GLP-1, a natural hormone that regulates appetite and blood sugar. However, tirzepatide has an added advantage because it also stimulates GIP receptors.

  • Semaglutide: Only targets the GLP-1 receptor.
  • Tirzepatide (Mounjaro): Targets both GLP-1 and GIP receptors, creating a more comprehensive approach to managing insulin and appetite.

Weight Loss Potential

Clinical trials have shown that both drugs are effective for weight loss, but tirzepatide consistently outperforms semaglutide. In a study comparing both drugs, patients using Tirzepatide lost significantly more weight than those using Semaglutide.

  • Semaglutide: In trials, Semaglutide helped participants lose an average of 15% of their body weight.
  • Tirzepatide: Participants using Tirzepatide lost up to 22.5% of their body weight in similar trials. This is one of the highest weight loss percentages recorded for any medication in this class.

Efficacy in Diabetes Management

Both medications effectively reduce HbA1c levels when managing type 2 diabetes. However, Tirzepatide has demonstrated superior glucose-lowering effects. In a head-to-head study known as SURPASS-2, participants taking Tirzepatide showed a greater reduction in HbA1c compared to those taking Semaglutide.

Side Effects

The side effects of both medications are similar, with the most common being gastrointestinal issues such as nausea, vomiting, and diarrhea. However, studies suggest that tirzepatide may cause slightly more severe side effects compared to semaglutide, particularly at higher doses.

3. Availability of Mounjaro in Thailand

As of now, semaglutide is widely available in Thailand, particularly under brand names such as Ozempic (for diabetes) and Wegovy (for weight loss). However, Mounjaro (Tirzepatide) is relatively new to the market, and its availability in Thailand is still limited but expected to grow in the coming months and years.

Many clinics and pharmacies offer semaglutide, but those interested in Mounjaro may need to consult specialized weight management or diabetes centers that introduce the medication to their patients.

In Thailand, the pricing and insurance coverage for these medications can vary significantly, with Semaglutide Thailand providing an affordable platform for acquiring Semaglutide. As Mounjaro becomes more readily available, it is likely to be offered at competitive prices, potentially similar to or slightly higher than Semaglutide, given its newer status and superior effectiveness.

4. FDA Approval and Clinical Trials

FDA Approval

The U.S. Food and Drug Administration (FDA) approved Mounjaro in May 2022 for the treatment of type 2 diabetes, based on promising clinical trial results. Despite being primarily a diabetes medication, its potent weight-loss effects have sparked discussions about whether it should also receive explicit approval for obesity.

Clinical Trials

Several clinical trials have explored the efficacy of Mounjaro (Tirzepatide) for weight loss and diabetes management.

  • SURPASS Clinical Trials: These trials compared Tirzepatide to a placebo and to other medications, including Semaglutide, in patients with type 2 diabetes. The results showed that patients using Tirzepatide experienced greater reductions in HbA1c and body weight compared to those using other treatments.
  • SURMOUNT-1 Study: This trial focused on patients with obesity or overweight and no diabetes. Participants who received the highest dose of tirzepatide lost an average of 22.5% of their body weight after 72 weeks, which far exceeds the results seen with semaglutide.

These studies indicate that tirzepatide not only improves glycaemic control but also offers unprecedented weight loss results, making it a game-changing treatment for both diabetes and obesity.

5. Is Mounjaro more effective than Semaglutide?

Based on the data from clinical trials and real-world applications, Mounjaro appears to be more effective than Semaglutide for weight loss and managing type 2 diabetes. Here’s why:

  • Dual Mechanism: The combination of GLP-1 and GIP receptor activation allows Mounjaro to better control blood sugar and suppress appetite, leading to more significant weight loss.
  • Greater Weight Loss: Participants in trials lost more weight with Tirzepatide (up to 22.5%) than with Semaglutide (up to 15%).
  • Improved Diabetes Control: Tirzepatide was shown to lower HbA1c levels more effectively than Semaglutide in head-to-head comparisons, making it a stronger option for those with type 2 diabetes.

Limitations

Although tirzepatide appears to be more effective, its novelty necessitates the collection of long-term data on its safety and efficacy. On the other hand, researchers have studied semaglutide for several years, making it an established option with a proven track record.

6. Future Outlook: Will Mounjaro Overtake Semaglutide?

Given its superior efficacy in both weight loss and glucose control, it is likely that Mounjaro (Tirzepatide) could overtake Semaglutide as the go-to medication for patients with type 2 diabetes and obesity. However, several factors, including availability, pricing, and long-term safety data, will determine how quickly this shift happens.

For now, semaglutide remains a highly effective and more widely available option, especially in places like Thailand where its use is well-established. As Mounjaro gains FDA approval for obesity (expected in the near future) and becomes more accessible globally, patients will have more powerful tools for managing their weight and metabolic health.
