Hormonal

Tirzepatide, a dual GIP/GLP-1 receptor agonist, produces statistically significant reductions in HbA1c and body weight in patients with type 2 diabetes and obesity, outperforming several existing antidiabetic classes including GLP-1 agonists and insulin.

Tirzepatide is a once-weekly injection that significantly lowers blood sugar and helps with weight loss in people with type 2 diabetes and obesity. It works by mimicking two natural hormones (GIP and GLP-1). Clinical trials show it is more effective than some existing diabetes medications and GLP-1 drugs alone. Common side effects include gastrointestinal issues, which are often worse at higher doses, so doctors usually start with a low dose and increase it slowly. It is not recommended for pregnant women.

Why this rating

Based on multiple Phase III trials (SURPASS, SURMOUNT) with large sample sizes, though the paper notes limited comparisons to non-GLP-1 drugs.
