Tirzepatide, a dual GLP-1 and GIP receptor agonist, ranked first among FDA-approved agents for both glycemic control and weight loss in a meta-analysis of 76 randomized trials involving 39,000 adults with type 2 diabetes.
The drug demonstrated superior efficacy with mean reductions of 2.1% in HbA1c, 3.11 mmol/L in fasting blood glucose, and 8.5 kg in body weight compared to placebo, outperforming semaglutide which ranked second.
Following its May 2022 market launch, tirzepatide achieved rapid uptake, reaching 12.3% of all glucose-lowering medication use by December 2023 and surpassing traditional therapies like metformin in incident prescriptions.
The medication's swift adoption represents a significant shift in diabetes and obesity treatment patterns, with implications for clinical practice guidelines and healthcare policy.
