National Trends in the Use of Sacubitril/Valsartan

J Card Fail. 2021 Aug;27(8):839-847. doi: 10.1016/j.cardfail.2021.05.015.

Abstract

Background: Better understanding of recent sacubitril/valsartan prescription patterns may help identify factors that influence its use. The aim of the study was to characterize sacubitril/valsartan use and dosage patterns nationally.

Methods and results: We conducted a population-level cohort study using IQVIA Inc. National Prescription Audit™ data in the United States from August 2016 to July 2019. Over 3 years, there was a 5.6-fold increase in the number of sacubitril/valsartan prescriptions dispensed per month, totaling 3.3 million prescriptions. For the most recent year, this extrapolates to a best-case scenario of 13.8% of patients with heart failure with reduced ejection fraction using sacubitril/valsartan, representing at most one-half of those eligible for sacubitril/valsartan use. During the most recent year, 48.7% of dispensed prescriptions were for the lowest strength (24/26 mg) and only 20.6% for the target strength (97/103 mg). A greater proportion of the target strength was used in younger patients (< 65years: 24.6%; ≥ 85: 11.1%; P<0.0001). Cardiologists prescribed 59.0% of all dispensed prescriptions, and noncardiologists showed a greater increase (7.5-fold vs 4.9-fold; P<0.0001) over time.

Conclusions: Recent use of sacubitril/valsartan has increased greatly in the United States; however, a substantial proportion of eligible patients with heart failure with reduced ejection fraction did not receive treatment, and only 1 in 5 prescriptions dispensed were for the target strength. Further exploration of barriers to the use of sacubitril/valsartan and dosing uptitration and their clinical implications warrant further evaluation.
