Hormonal

Tirzepatide, a dual GIP/GLP-1 receptor agonist, produces dose-dependent reductions in HbA1c (up to 2.4%) and body weight (up to 11.3 kg) in patients with Type 2 Diabetes, with efficacy superior to the GLP-1 receptor agonist dulaglutide.

If you have Type 2 Diabetes, Tirzepatide is a once-weekly injection that significantly lowers blood sugar (HbA1c) and promotes substantial weight loss, outperforming existing GLP-1 drugs like dulaglutide in clinical trials. It works by mimicking two gut hormones (GIP and GLP-1) to improve insulin response and reduce appetite. While gastrointestinal side effects like nausea are common, they are usually mild and can be managed by starting with a low dose and increasing gradually. This treatment is suitable for adults with T2DM, including those already taking metformin.

GoodSupportsHIGH confidence
In the phase 1 and phase 2 trials tirzepatide demonstrated dose-dependent reduction in HbA1c (up to 2.4%) and body weight (up to 11.3 kg) in patients with T2DM. The clinical efficacy of tirzepatide is superior to the GLP-1 RA dulaglutide.
