INCRETINS ANALOGS

GLP-1 Receptor Agonists (GLP-1 RAs)

GLP-1 RAs are a class of FDA-approved prescription medications that are used to help people lose weight. They work by mimicking the effects of a naturally occurring hormone called glucagon-like peptide-1 (GLP-1). GLP-1 helps to regulate appetite, slow down stomach emptying, and increase insulin production.

GLP-1 RAs have been shown to be very effective for weight loss. In clinical trials, people who took GLP-1 RAs lost an average of 15% of their body weight over the course of a year. This is significantly more weight loss than is typically seen with other weight loss medications or lifestyle changes alone.

In addition to weight loss, GLP-1 RAs have also been shown to improve a number of other health conditions, including:

  • Type 2 diabetes
  • High blood pressure
  • High cholesterol
  • Heart disease
  • Stroke
  • Cancer
 

GLP-1 RAs are generally safe and well-tolerated. However, they can cause some side effects, such as nausea, vomiting, diarrhea, and constipation. These side effects are usually mild and go away on their own.

If you are considering taking GLP-1 RAs, talk to your doctor about the risks and benefits. GLP-1 RAs may not be right for everyone, but they can be a very effective way to lose weight and improve your health.

How GLP-1 RAs Work?

GLP-1 RAs work by binding to GLP-1 receptors on cells in the brain, stomach, pancreas, and liver. When GLP-1 RAs bind to these receptors, they send signals that:

  • Reduce appetite
  • Slow down stomach emptying
  • Increase insulin production
  • Decrease glucagon production
 

These effects lead to weight loss in a number of ways. First, reduced appetite means that you eat less food. Second, slowed stomach emptying makes you feel full for longer after eating. Third, increased insulin production helps your body use glucose for energy, which can help you burn more calories. Fourth, decreased glucagon production helps to prevent your liver from releasing stored glucose into the bloodstream, which can also help you lose weight.

Who Can Take GLP-1 RAs?

GLP-1 RAs are generally safe for most people to take. However, they are not recommended for people with certain medical conditions, such as:

  • Pancreatic cancer
  • Medullary thyroid cancer
  • Multiple endocrine neoplasia type 2 (MEN2)
  • Severe gastroparesis
  • Active inflammatory bowel disease
 

If you have any of these conditions, talk to your doctor about whether GLP-1 RAs are right for you.

What Are the Side Effects of GLP-1 RAs?

The most common side effects of GLP-1 RAs are:

  • Nausea
  • Vomiting
  • Diarrhea
  • Constipation
  • Headache
  • Fatigue
  • Dizziness

  • Indigestion
  • Gas

These side effects are usually mild and go away on their own. If you experience any side effects that are bothersome or do not go away, talk to your doctor.

If you are interested in taking GLP-1 RAs, talk to your doctor about the costs involved. There are a number of resources available to help you get the medication you need, even if you have limited financial resources.

Tirzepatide

Tirzepatide (Mounjaro®) is a medication designed for adults with type 2 diabetes that is administered once a week via injection. This drug helps regulate blood sugar levels by binding to GLP-1 and GIP receptors in the pancreas and intestine. However, it is crucial to note that Mounjaro is only suitable for some. 

Individuals with a history of medullary thyroid cancer or pancreatitis should not use it, and it is not recommended for pregnant or breastfeeding women.

While Mounjaro can be an effective treatment for type 2 diabetes, it may cause some side effects such as nausea, vomiting, diarrhea, constipation, and headache. These side effects are usually mild and subside on their own. Still, if they persist or become severe, it is essential to consult with a doctor.

Mounjaro is FDA-approved for adults with type 2 diabetes who have not achieved their blood sugar goals with other medications. Although it is not currently approved for weight loss in patients without diabetes, ongoing studies suggest that it may receive this indication in the future. The starting dose of Mounjaro is 0.25 milligrams (mg), which can be increased up to 15 mg depending on how well it works for the individual. It is most effective when used in conjunction with a healthy diet and exercise regimen.

Overall, Mounjaro is the first and only FDA-approved medication that is a dual GLP-1 and GIP receptor agonist, providing two different ways to help regulate blood sugar levels. If you have any questions or concerns about Mounjaro, it is recommended that you speak to your medical team.
