Higher semaglutide dose boosts weight loss in obesity trials

October 05, 2025 በAI የተዘገበ

Two phase 3 clinical trials show that a 7.2 mg weekly dose of semaglutide leads to greater weight loss than the approved 2.4 mg dose in adults with obesity, including those with type 2 diabetes. Nearly half of participants on the higher dose lost 20% or more of their body weight over 72 weeks. The results, published in The Lancet Diabetes & Endocrinology, suggest improved metabolic health with a favorable safety profile.

AstraZeneca Cuts Prices on Select US Drugs After Trump Pressure
