In talking to healthcare leaders about drug utilization, I’ve fielded many questions concerning the application of clinical evidence to specific drugs and drug categories. I address one popular topic below.
DEAR LUMERE: I’m a pharmacy clinical coordinator, and my hospital’s cardiologists are clamoring for Entresto (sacubitril/valsartan) to treat patients with chronic heart failure. They point to strong efficacy data and last year’s updated American College of Cardiology/American Heart Association guidelines that recommend it over ACE inhibitors and ARBs. Should we add Entresto to our inpatient formulary? – UNCLEAR ABOUT ENTRESTO
DEAR UNCLEAR ABOUT ENTRESTO: Let’s look at your question from three angles:
- Patient safety: Switching from an angiotensin-converting enzyme (ACE) inhibitor to Entresto requires a 36-hour washout period to eliminate the risk of angioedema. Therefore, patients who were previously on therapy cannot start Entresto immediately upon admission.
- Cost effectiveness: Entresto can cost two orders of magnitude more than ACE inhibitors and angiotensin receptor blockers (ARBs). While some studies have shown that Entresto meets commonly accepted incremental cost-effectiveness thresholds over a patient’s lifetime, the short-term incremental cost-effectiveness is much harder to justify.1, 2
- Limited patient population: Entresto is appropriate only for approximately 40% of patients with heart failure.3 It was not widely adopted in its first year and last year fell $30M short of a projected $200M in global sales.
Given these factors, patients should not be starting Entresto in the inpatient setting, and it doesn’t make sense for most hospitals to carry it on their shelves.
