Evaluating the Safety and Tolerability of Sacubitril/Valsartan for HFrEF Managed Within a Pharmacist Clinic.

ABSTRACT

OBJECTIVE: The objective of this research was to describe the use of pharmacist-managed sacubitril/valsartan therapy in a multi-center, outpatient cardiac group. BACKGROUND: Sacubitril/valsartan, an angiotensin receptor-neprilysin inhibitor (ARNi), is a novel agent for the treatment of heart failure. An ARNi is recommended by national guidelines to be used in place of angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) therapy for patients who remain symptomatic. METHODS: A retrospective chart review was performed to identify patients initiated and fully titrated on sacubitril/valsartan therapy from July 7, 2015 to March 7, 2017. RESULTS: Fifty-two of the 72 symptomatic heart failure with reduced ejection fraction (HFrEF) patients prescribed sacubitril/valsartan during the 21-month period were included in this analysis. The average ejection fraction was 26%. The average age was 69 years. At baseline, 26.9% of patients were not on ACEi/ARB therapy and 13.5% were on target-dose therapy. After completing the uptitration process, the maximally tolerated dose of sacubitril/valsartan was 5.8% low-dose, 7.7% mid-dose, and 86.5% target-dose. Loop and thiazide diuretic use decreased significantly. There was a significant mean reduction in systolic blood pressure of 6 mmHg with no significant changes in serum creatinine, blood urea nitrogen, or potassium levels. CONCLUSIONS: With close monitoring and follow-up, ARNi therapy was a safe alternative to ACEi/ARB therapy for chronic symptomatic HFrEF when initiated within a pharmacist clinic.
