Overview

What is Mazdutide?

Mazdutide is a dual GLP-1 and glucagon receptor agonist developed by Innovent Biologics for obesity and type 2 diabetes. It has shown up to 14% weight loss in Phase 3 trials and significant liver fat reduction in MASH studies. The dual mechanism provides synergistic effects on appetite, energy expenditure, and metabolic health.

Key Benefits

Superior weight loss through dual mechanism, significant liver fat reduction, improved glycemic control, once-weekly dosing convenience.

Mechanism of Action

Mazdutide activates both GLP-1 and glucagon receptors. GLP-1 activation reduces appetite and improves insulin secretion, while glucagon activation increases energy expenditure and promotes hepatic lipid metabolism.

What to Expect

  • Week 1-4: GI adaptation, appetite reduction begins
  • Week 4-12: Significant weight loss acceleration
  • Week 12-24: Continued weight loss, metabolic improvements
  • Week 24+: Sustained weight management

Side Effects & Safety

Side Effects

  • Most common: nausea, vomiting, diarrhea (GI symptoms)
  • Typically mild to moderate and transient
  • Dose escalation helps minimize GI side effects
  • Contraindicated in personal/family history of medullary thyroid carcinoma
  • Not recommended during pregnancy or breastfeeding

When to Stop

  • Severe GI symptoms
  • Signs of pancreatitis
  • Allergic reactions
  • As directed by healthcare provider
