Tesofensine vs Semaglutide Compared: Difference, Pros and Cons for Weight Loss

Tesofensine and semaglutide are gaining attention as options for weight loss treatment. Given the global challenges posed by obesity, understanding how these medications work can help individuals and healthcare providers make informed decisions about weight management.

‍

Both tesofensine and semaglutide have an impact on weight loss, as clinical trials show. They work and offer unique benefits and drawbacks. This article provides a comparison of these two drugs, including how they work and how they might interact with other medications. We’ll also take a look at the good and bad points of tesofensine and semaglutide.

‍

Key Takeaways

• Tesofensine is a triple monoamine reuptake inhibitor that curbs appetite by increasing levels of serotonin, norepinephrine, and dopamine in the brain ^[1].

• Semaglutide is a GLP-1 receptor agonist that improves blood sugar control and promotes satiety ^[1].

• Tesofensine is taken as a daily oral tablet, while semaglutide is administered as a weekly subcutaneous injection ^[1].

• While some studies suggest that Tesofensine may result in early weight loss, the timing and extent of weight loss can vary significantly among individuals. Semaglutide, on the other hand, may take several weeks to show noticeable effects. Both medications should be used under the guidance of a healthcare provider.

• Both medications have shown promise in clinical trials for obesity treatment, with semaglutide demonstrating significant weight reduction in recent studies ^[2].

• Tesofensine is currently approved in Europe and some other countries but not in the United States. Semaglutide is FDA-approved for chronic weight management under the brand names Ozempic and Wegovy ^[1].

‍

What Is Semaglutide?

Semaglutide is a drug that falls under glucagon-like peptide-1 (GLP-1) receptor agonists [3]. Scientists first created it to treat type 2 diabetes, but semaglutide has been prescribed off-label for its effect on weight loss [4]. This treatment copies the GLP-1 hormone, which our gut makes when we eat [3].

‍

Semaglutide acts as a GLP-1 receptor agonist. It attaches to GLP-1 receptors in the brain that control appetite [5]. When it activates these receptors, semaglutide has an influence on feelings of fullness and hunger. This leads people to make better food choices and eat fewer calories [4]. This process plays a key part in managing weight.

‍

The medication has an influence on more than just appetite reduction. Semaglutide makes the stomach empty slower, which keeps you feeling full longer after eating [4]. This helps to control cravings and resist overeating. Also, semaglutide affects the brain's reward centers, making high-calorie indulgent foods less appealing [4].

‍

Semaglutide has an impact on weight loss in several ways. It boosts basal metabolic rate, which leads to more calorie burning even when not active [4]. Also, this drug helps to break down stored fat through lipolysis, which taps into energy reserves and helps with weight loss [4].

‍

You need a consultation with a qualified healthcare provider in order to find out if you are a good candidate for a prescription for compounded semaglutide. Your doctor will decide if semaglutide is right for you and which type: either the injectable form of semaglutide (Wegovy^®, Ozempic^®) or one of the oral forms of semaglutide (Rybelsus^®, SubMagna™).

‍

How Does Semaglutide Work?

Semaglutide acts like a glucagon-like peptide-1 (GLP-1) receptor agonist, copying the natural GLP-1 hormone the gut makes [3]. This drug has a 94% match with human GLP-1 and has a special chemical makeup that boosts how well it works [6].

‍

The main way semaglutide works is by turning on GLP-1 receptors in different parts of the body. In the pancreas, it makes insulin release go up and glucagon release go down, which helps keep blood sugar levels in check [6]. This happens because of the mTOR-dependent HIF-1α activation pathway, which causes pancreatic β-cells to break down glucose and release insulin [6].

‍

Semaglutide has an influence on weight loss in many ways. It affects the brain's appetite control centers, making people feel fuller and less hungry [3]. Semaglutide also makes the stomach empty more slowly, which keeps people feeling full longer after meals and helps stop food cravings [4].

‍

Semaglutide typically begins to suppress appetite within a few days to a week of starting the medication, with more noticeable effects developing over the first few weeks. Sticking to semaglutide safety guidelines will help you cut down on possible side effects and get the best results as you work to manage your weight.

By mimicking a natural hormone that controls hunger and blood sugar, semaglutide tablets work by helping people manage their weight by reducing food cravings. Semaglutide comes in pill form, as a sublingual suspension, and as an injection. Each type has its pros and cons, and there are several factors to consider when deciding between semaglutide tablets vs injections.

If you need a more customized dose or formulation of semaglutide that’s not available in regular prescriptions, compounded semaglutide can be a great option. It offers flexibility to meet your specific needs. Talk with your healthcare provider to ensure it’s safe, effective, and sourced from a reputable source like Eden.

What Is Tesofensine?

Tesofensine is a new drug that's gaining attention for weight control. Scientists first used this drug to treat Alzheimer's disease, but during testing, they found something unexpected: patients lost a significant amount of weight [8]. This surprise led scientists to shift their focus. Now, they're looking at tesofensine to help people lose weight.

‍

Tesofensine functions primarily as an appetite suppressant and has shown potential in early studies for supporting weight loss. Its use is still under investigation, and it is not approved in all countries, including the United States. 

‍

It works by adjusting key brain chemicals serotonin, norepinephrine, and dopamine [8]. By impacting these brain chemicals, tesofensine helps to manage appetite and cut down food cravings, which makes it easier for people to eat less and stop overeating. 

‍

One thing that stands out about tesofensine is how it tackles weight loss from two angles. 

Besides curbing your appetite, this drug also has an impact on how your body burns energy. Research shows tesofensine boosts the calories your body uses up even when you're not doing anything [8]. This kick to your metabolism helps you lose weight by making your body burn more calories than you eat.

‍

The combination of curbing hunger and speeding up metabolism gives tesofensine a strong impact on battling obesity. As studies continue, tesofensine might offer an alternate choice for people struggling with weight control, offering a way to reach and maintain a healthy weight.

‍

If you're considering semaglutide alternatives, options like tesofensine or other GLP-1 receptor agonists might be effective for weight management and blood sugar control. It's important to discuss these alternatives with your healthcare provider to determine the best fit for your needs and health goals.

‍

How Does Tesofensine Work?

Tesofensine operates as a triple monoamine reuptake inhibitor, affecting neurotransmitters such as serotonin, norepinephrine, and dopamine. These neurotransmitters play roles in regulating appetite and metabolism. Its main job is to stop the reuptake of norepinephrine (NE), serotonin (5-HT), and dopamine (DA) [9]. This special action makes more of these neurotransmitters available in synapses, which has a big impact on how we control our appetite and use energy.

‍

The appetite-suppressing effect of tesofensine has an influence on norepinephrine and dopamine pathways. Tesofensine blocks NE reuptake, which stimulates α1 adrenoceptors. This plays a key role in reducing food intake [9]. Also, the drug inhibits DA reuptake. This leads to increased D1 receptor activity, which adds to its hypophagic effect [9].

‍

Tesofensine has an influence on weight loss that goes beyond curbing appetite. The drug also boosts the body's energy use, which ramps up metabolism [8]. This two-pronged approach of cutting down calorie intake while at the same time burning more calories sets the stage for losing weight.

‍

Research on animals has given us a peek into how tesofensine works. When scientists tested obese rats, they found that prazosin, a drug that blocks α1 adrenoceptors, reduced tesofensine's ability to cut down food intake [9]. In a similar way, SCH23390, which blocks D1 receptors, stopped tesofensine from lowering food intake. This shows that dopamine pathways play a key role in how tesofensine does its job [9].

‍

In contrast to other monoamine reuptake blockers, tesofensine's appetite-suppressing effects don't seem to rely as much on serotonin activity [9]. This sets tesofensine apart from other weight loss drugs and might explain why it works so well as a possible obesity treatment.

Semaglutide and Tesofensine Compared

Tesofensine: Weight Loss Effectiveness

Tesofensine, a triple monoamine reuptake inhibitor, has an influence on weight loss, as clinical trials show. Research indicates that tesofensine, along with diet, exercise, and lifestyle changes, can help people lose about 6 to 8 percent of their body weight over 12 weeks [10]. This drug impacts appetite and metabolism to burn fat fast, and many people see results in just 1-2 weeks after starting treatment [1].

‍

Semaglutide: Weight Loss Effectiveness

Semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, has an influence on substantial weight loss. The STEP 1 trial showed that semaglutide 2.4 mg caused a 14.9% drop in weight compared to 2.4% with placebo at week 68 [11]. This drug makes people feel full, reduces hunger, and slows down how fast the stomach empties [1]. The weight loss benefits of semaglutide take time to show up, and it often takes four weeks or more to start working [1].

‍

Tesofensine: Safety

Tesofensine has been associated with side effects such as nausea, constipation, dry mouth, headaches, and insomnia. Additionally, it may increase heart rate and blood pressure in some individuals. These potential side effects highlight the importance of medical supervision when using Tesofensine. In rare instances, tesofensine has a link to anxiety, agitation, depression, and more concerning effects like hallucinations, psychosis, and seizures [10].

‍

Semaglutide: Safety

Common side effects of Semaglutide include gastrointestinal issues such as nausea, vomiting, abdominal pain, diarrhea, and constipation. It is important to discuss any side effects with a healthcare provider to ensure safe and effective use. Some patients might feel bloated and have heartburn. These gut-related effects, while mild, seem to happen more often than with tesofensine [1]. In rare cases, patients have reported fuzzy vision and feeling confused [10].

‍

Semaglutide stays in your system for about one week. With this length of half-life, semaglutide will stay in your system for several weeks after you take your final dose. Sticking to semaglutide safety guidelines will help you cut down on possible side effects and get the best results as you work to manage your weight.

‍

Tesofensine: Cost

Tesofensine has been approved in Europe, Mexico, Argentina, and several other nations, but not in the United States. This means we can't get exact price information for this drug [1]. The cost of Tesofensine can vary significantly depending on the country and availability, and it is important to consult a healthcare provider for accurate pricing and to discuss the financial aspects of treatment. 

‍

Prices can range from $300 to $500 or more for a month's supply, depending on the dosage and the provider  [1]. It's important to consult with a healthcare provider before using tesofensine, as it may not be approved for use in some countries and could have significant side effects or risks.

‍

Semaglutide: Cost

The semaglutide costs can add up quickly if your insurance doesn't cover it. Semaglutide has FDA approval to manage chronic weight in the United States. You can find it under the brand names Ozempic and Wegovy. If you don't have insurance, these drugs will set you back about $1,000-$1,500 each month. Some insurance plans may cover semaglutide, but they often need prior authorization and put limits on how long they'll approve it [1].
