As one of the most effective GLP-1 receptor agonists (GLP-1RAs), tirzepatide has demonstrated superior efficacy in reducing HbA1c levels (-2.10%) and fasting plasma glucose concentrations (-3.12 mmol\/L), offering unmatched glycemic control. It also provides significant benefits in weight management, with an average reduction of -8.47 kg, making it a powerful tool for addressing the \"\"twin epidemics\"\" of diabetes and obesity.
