What is Zepbound®
(Mounjaro® - tirzepatide)?
If you're researching medical weight loss options, you've likely come across Zepbound® and Mounjaro®, two medications containing tirzepatide. These treatments have become increasingly popular for their effectiveness in helping individuals lose weight and manage related health conditions. At Phoenix NP, we offer tirzepatide-based medical weight loss programs tailored to your goals, with transparent plans and pricing that fit your lifestyle.
What is Tirzepatide?
Tirzepatide is a medication used to treat type 2 diabetes and obesity. It's a once-weekly injectable drug that's available under two brand names: Zepbound® and Mounjaro®. Tirzepatide is unique in which it has two mechanisms of action on the body. Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. Similar to Ozempic® and Wegovy®, it mimics the naturally occurring GLP-1 hormone to help regulate blood sugar and appetite, but it also mimics the naturally occurring GIP hormone to increase your sensitivity to insulin.
What this means is that tirzepatide works on your digestive system in two different, but complementary ways, to regulate your sugar levels, digestion, and appetite.
Zepbound® and Mounjaro® are two branded versions of tirzepatide:

Zepbound®
is specifically approved for chronic weight management in adults with obesity or overweight. It is also approved for treating moderate-to-severe obstructive sleep apnea (OSA) in adults with obesity.

Mounjaro®
is approved for managing type 2 diabetes but is also widely used off-label for weight loss.
How Does Zepbound® Help With Weight Loss?
When used in conjunction with a healthy diet and increased physical activity, Zepbound® has been shown to help patients lose an average of between 15% to 20.9% of their body weight over time. The medication works by:
-
Reducing appetite
-
Controlling cravings
-
Slowing gastric emptying
-
Improving insulin sensitivity
This comprehensive approach makes Zepbound® especially beneficial for individuals who have struggled with traditional diet and exercise alone.
Who is a Candidate for Zepbound®?
You may be a good candidate for Zepbound® treatment if:
-
Your BMI is 30 or higher, or
-
Your BMI is 27 or higher with at least one weight-related condition (e.g., high blood pressure, type 2 diabetes, or high cholesterol)
If your BMI is under 27, you may still be a candidate to be prescribed Zepbound®, depending on your medical history, lab results, or previous use of the medications. At Phoenix NP, our licensed medical providers will assess your health history and goals to determine if Zepbound® or a similar treatment is right for you.
