Core Viewpoint - The article discusses the current landscape of weight loss medications in China, focusing on the differences between new-generation GLP-1 drugs and traditional weight loss medications, highlighting their mechanisms, efficacy, and safety profiles [4][7]. Group 1: Overview of Weight Loss Medications - There are six weight loss drugs currently approved in China, including three new-generation GLP-1 drugs: Semaglutide, Tirzepatide, and Mounjaro, and three traditional drugs: Benaglutide, Liraglutide, and Orlistat [4][7]. - New-generation GLP-1 drugs have longer action times and more significant weight loss effects compared to first-generation drugs [4][6]. Group 2: Mechanisms and Administration - The six weight loss drugs differ in their mechanisms of action and target populations, with new-generation drugs showing better safety and efficacy [7]. - All approved GLP-1 weight loss medications are currently available only as subcutaneous injections, with no oral versions available yet [6]. Group 3: Indications and Contraindications - Weight loss medications should be considered for patients who have not achieved a weight loss of at least 5% after three months of lifestyle intervention, even for those who are merely overweight without complications [9]. - A comprehensive assessment is necessary before starting medication, especially for high-risk populations such as the elderly or those with liver and kidney dysfunction [10]. Group 4: Clinical Application Process - Diagnosis of obesity or overweight should consider BMI, metabolic indicators, and related comorbidities, with obesity defined as BMI ≥ 28 kg/m² [12]. - The selection of medications should prioritize those with additional clinical benefits for patients with comorbid conditions like type 2 diabetes or cardiovascular diseases [13]. Group 5: Monitoring and Management - Regular monitoring of body composition and metabolic indicators is essential, with evaluations occurring monthly during the initial three months and quarterly thereafter [16]. - For elderly patients, careful consideration of muscle mass and potential drug interactions is crucial, with recommendations for dose adjustments based on renal and hepatic function [19].
