What is tirzepatide used for?
Tirzepatide is an injectable medication mainly used for:
Treatment of type 2 diabetes
It provides very effective blood-glucose control.Weight loss / obesity management
It is prescribed for people with obesity or overweight with related risk factors, leading to significant and sustained weight reduction.
It is considered a next-generation medication because it targets two metabolic hormones at the same time, making it more potent than similar drugs.
How does it work?
Tirzepatide is a dual GIP and GLP-1 receptor agonist (incretin hormones):
GLP-1
Reduces appetite

GIP
Improves insulin response to glucose
Enhances the effect of GLP-1
Improves insulin sensitivity
Combined effect
👉 Less hunger
👉 Longer-lasting satiety
👉 Better blood sugar control
👉 Progressive weight loss
