Low adoption of weight loss medications: A comparison of prescribing patterns of antiobesity pharmacotherapies and SGLT2s
Abstract
OBJECTIVE: To characterize the adoption of antiobesity pharmacotherapies, as compared with that of the newest antidiabetes pharmacotherapy, subtype 2 sodium-glucose transport protein inhibitors (SGLT2s), among prescribers in the United States.
METHODS: A retrospective analysis of 2012 to 2015 data extracted from the IMS Health National Prescription Audit™ and Xponent™ assessed adoption rates of antiobesity pharmacotherapies and SGLT2s.
RESULTS: The number of dispensed antidiabetes prescriptions was 15 times the number of dispensed antiobesity prescriptions. The antiobesity market share was: 74.0% phentermine, 18.6% new antiobesity pharmacotherapies. The mean increase in prescriptions/month were: 25,259 for SGLT2s, 5,154 for new antiobesity pharmacotherapies, and 2,718 for phentermine. Medical specialties prescribing the majority of the analysis medications were Family Medicine/General Practice and Internal Medicine. Endocrinology had the highest prevalence of prescribers of any subspecialty.
CONCLUSIONS: The adoption rate of SGLT2s was nearly exponential, while the adoption rate of new antiobesity pharmacotherapies was linear. Considering the relative prevalence of obesity to diabetes and that obesity is a major cause of diabetes, these results are paradoxical and suggest systematic barriers against the prescribing of antiobesity pharmacotherapies. The under-prescribing of antiobesity pharmacotherapies is widely acknowledged, but this is the first prescription data of these…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
