Abstract
Objective: Obesity affects more than 40% of US adults, increasing risks for cardiovascular disease and type 2 diabetes. Glucagon-like peptide 1 receptor agonists (GLP-1 RAs), initially indicated for diabetes, show promise in weight loss but face coverage issues, high costs, and premature prescribing from physicians. Research is needed to assess prescribing patterns, especially in patients without diabetes.
Study design: We conducted a retrospective, population-based, observational study using the Merative MarketScan Commercial Database and the Merative MarketScan Medicare Supplemental Database, which capture person-specific clinical utilization and expenditures. We analyzed GLP-1 RA prescribing rates from 2018 to 2023, comparing semaglutide with other GLP-1 RAs and stratifying by diabetes and overweight/obesity indications.
Methods: The study included individuals 18 years or older with 12 months of continuous enrollment from 2018 to 2023, categorizing GLP-1 RA users into 4 groups based on diabetes and obesity/overweight diagnosis codes within a year of their index date.
Results: Prescribing of GLP-1 RA medications, particularly semaglutides, increased notably over the years, whereas dulaglutide, liraglutide, and exenatide use declined. When investigating possible premature prescribing by examining users with no diabetes indication, the number of prediabetes or abnormal glucose diagnoses increased slightly before the index GLP-1 RA prescribing index date. However, less than 9% received a diabetes or prediabetes diagnosis 30 days after starting a GLP-1 RA.
Conclusions: From 2018 to 2023, GLP-1 RA prescribing increased significantly, with semaglutide approved for weight loss rising to 60% share in the nondiabetic obese/overweight group. Trends showed a notable rise in prescriptions for nondiabetic and obese/overweight patients.
