BACKGROUND: The uptake of novel lipid-lowering therapy (LLT) has been low; however, variations in clinician prescribing patterns have not been well studied. This study sought to describe early prescribing patterns of novel LLT and identify factors associated with high usage. METHODS: We identified prescriptions for any LLT using pharmacy transaction data (covering >80% of the United States) from January 1, 2018 to December 31, 2022, and identified patients newly initiated on PCSK9i (proprotein convertase subtilisin/kexin type 9 inhibitor) monoclonal antibodies or bempedoic acid (BA). We assessed the proportion of LLT prescribers overall and by specialty who had prescribed PCSK9i and BA, and the volume of patients prescribed. The association between use of PCSK9i and BA was assessed. RESULTS: Of 996 421 LLT prescribers, only 9.2% (N=91 166) and 2.4% (N=23 674) had prescribed PCSK9i and BA, respectively, by December 31, 2022. Usage was higher among cardiologists, but still only 62.8% and 18.2% of cardiologists had given a PCSK9i or BA prescription. The top 10% of prescribers were responsible for starting 57.3% and 51.2% of PCSK9i and BA prescriptions, respectively. CONCLUSIONS: The majority of US clinicians prescribing LLT have never prescribed a PCSK9i or BA, and among those who do, most have used these therapies in only a few patients. However, there exist distinct groups of early adopters and high-volume users with higher approval rates, slightly more years in practice, and ...
