Tirzepatide Targets GLP-1 and GIP Receptors
Zepbound is an FDA-approved prescription medication for chronic weight management. Its active ingredient is tirzepatide, the same compound found in Mounjaro, a diabetes treatment. Above all, Zepbound activates GLP-1 and GIP receptors, hormones that regulate appetite, insulin levels, and metabolism in the human body. This multi-action mechanism gives a fuller feeling, reduces cravings, and improves the body’s ability to digest food efficiently. These actions play a major part in reducing stubborn body fat, without a doubt.
FDA Approvals for Obesity and Obstructive Sleep Apnea
In 2023, the FDA approved Zepbound for chronic weight management in adults with obesity. More recently, it also gained approval for treating obstructive sleep apnea (OSA) in patients with obesity. Certainly, these approvals highlight the growing role of Zepbound in addressing multiple weight-related health conditions.
Zepbound vs Other Weight Loss Medications
Zepbound Dosage and Administration
Starting Dose: How to Begin Safely
Most patients start with 2.5 mg once weekly. In fact, this allows the body to adjust and minimizes side effects.
Dosage Escalation and Titration Schedule
After the first 4 weeks, the dose is gradually increased:
- 5 mg → 7.5 mg → 10 mg → up to 15 mg weekly.
Escalation depends on patient tolerance, side effects, and weight loss results.
Maintenance Dose and Maximum Recommended Levels
The maintenance dose usually ranges between 2.5–15 mg weekly. Therefore, it depends on individual progress and response to therapy.
What to Do if You Miss a Zepbound Dose
- If you miss a dose, take it within 4 days.
- If more than 4 days have passed, skip the missed dose and continue your regular weekly schedule.
Zepbound Guide to Injection Instructions, Site Rotation, and Storage Tips
Follow these guidelines to ensure safe and effective use:
- Administer Zepbound as a subcutaneous injection in the stomach, thigh, or upper arm.
- Rotate injection sites weekly to avoid irritation.
- Store pens in the refrigerator at 36°F to 46°F (2°C to 8°C), but never freeze them.

Integrating Other Weight Loss Medications
Medications like Zepbound or Wegovy can be powerful tools to support weight loss. Along with a healthy diet and lifestyle, it gives effective results. Certainly, Wegovy (semaglutide) works by targeting GLP-1 receptors to help reduce appetite and improve blood sugar control. Because dosage schedules and responses can vary between medications, understanding how semaglutide is administered can provide helpful context for anyone exploring weight management options.
Clinical Results and Weight Loss Outcomes with Zepbound
Key Clinical Trials: SURMOUNT Studies
The table below summarizes the Zepbound SURMOUNT clinical trials, showing how different weekly doses of tirzepatide (5 mg, 10 mg, 15 mg) affected weight loss and diabetes-related outcomes in adult participants across SURMOUNT-1 to SURMOUNT-4.
| Trial | Participants & Baseline | Dosing Groups | Mean % Weight Change (Week 72–88) | % with ≥5% Weight Loss |
|---|---|---|---|---|
| SURMOUNT-1 | N = 2,539 Weight: 104.8 kg BMI: 38.0 |
5 mg, 10 mg, 15 mg, Placebo | 5 mg: −15.0% 10 mg: −19.5% 15 mg: −20.9% Placebo: −3.1% |
5 mg: 85% 10 mg: 89% 15 mg: 91% Placebo: 35% |
| SURMOUNT-2 | N = 938 Weight: 100.7 kg BMI: 36.1 |
10 mg, 15 mg, Placebo | 10 mg: −12.8% 15 mg: −14.7% Placebo: −3.2% |
10–15 mg: 79–83% Placebo: 32% |
| SURMOUNT-3 | N = Not specified Adults with obesity/overweight (after 12-week lifestyle program) |
10 mg, 15 mg, Placebo | Greater weight loss with tirzepatide vs placebo over 72 weeks | Most participants achieved ≥5% loss |
| SURMOUNT-4 | N = 670 Weight: 107.3 kg |
Tirzepatide (continued) vs Placebo (withdrawal) | Week 36–88: Tirzepatide: −5.5% Placebo: +14.0% Overall: −25.3% vs −9.9% |
Maintained ≥80% of weight loss: 89.5% (tirzepatide) vs 16.6% (placebo) |
Notes:
- Weight loss is expressed as a percentage of baseline body weight.
- Diabetes outcomes (HbA1c) were only evaluated in SURMOUNT-2, as the other trials included non-diabetic participants.
- Maximum tolerated dose (MTD) in SURMOUNT-3 & 4 allowed adjustments based on GI tolerability.
