Mechanism of Action
Tirzepatide:- Dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist
- Activates both GIP and GLP-1 receptors
- Selective GLP-1 receptor agonist
- Activates only GLP-1 receptors
Effectiveness for Weight Loss
Tirzepatide:- Associated with greater weight loss compared to semaglutide
- In a study of adults with overweight or obesity:
- Patients were 1.76 times more likely to achieve ≥5% weight loss
- 2.54 times more likely to achieve ≥10% weight loss
- 3.24 times more likely to achieve ≥15% weight loss compared to semaglutide
- Effective for weight loss, but generally less so than tirzepatide
- Approved for chronic weight management in adults with obesity or overweight with at least one weight-related condition
Effectiveness for Type 2 Diabetes
Both medications are effective in treating type 2 diabetes, but tirzepatide has shown superior results:Tirzepatide:- In a 40-week trial, tirzepatide at doses of 5 mg, 10 mg, or 15 mg was superior to semaglutide 1 mg in reducing glycated hemoglobin levels
- 82-86% of patients reached the target glycated hemoglobin level of <7.0%
- Effective in lowering blood sugar levels in adults with type 2 diabetes
- 79% of patients reached the target glycated hemoglobin level of <7.0% in the same trial
Dosage and Administration
Tirzepatide (Zepbound):- Weekly subcutaneous injection
- Dosage increased over 4-20 weeks to target doses of 5 mg, 10 mg, or 15 mg
- Weekly subcutaneous injection
- Typical dose for weight loss is 2.4 mg
Side Effects
Both medications have similar side effect profiles, with gastrointestinal issues being the most common:- Nausea
- Diarrhea
- Vomiting
- Constipation
- Abdominal discomfort
Considerations
- Tirzepatide is a newer medication, approved by the FDA in November 2023 for chronic weight management
- Semaglutide has been in use longer and has more established safety data
- Both medications should be used in conjunction with diet and exercise for optimal results
- Neither medication is recommended for patients with a history of medullary thyroid cancer or Multiple Endocrine Neoplasia syndrome type 2
