Real‐world treatment patterns of sacubitril/valsartan: a longitudinal cohort study in Germany

AIMS: To analyse real-world treatment patterns of sacubitril/valsartan (sac/val) using data from a pharmacy database in Germany. METHODS AND RESULTS: A retrospective cohort study of 26 191 adult patients (aged ≥ 18 years) in the IMS® longitudinal prescriptions database in Germany who were dispensed sac/val from January 2016 to June 2017 was conducted. The analysis included sac/val dose titration assessed in the 6 months from first sac/val prescription; prescriptions of concomitant cardiovascular medications in the 6 months pre- and post-index and compliance and persistence during 12 months post-index. Two-thirds of patients were prescribed the lowest sac/val dose of 50 mg twice daily (b.i.d.) at index and up-titration during the first 6 months was attempted in 41% of these patients. Ten percent of patients prescribed 200 mg b.i.d. at index had to be stably down-titrated; among patients prescribed 50 or 100 mg b.i.d. at index that were up-titrated, > 80% remained on the higher dose. Overall, the mean daily diuretic dose decreased by 25% after initiation of sac/val. High compliance and persistence rates were observed across sac/val doses, increasing with higher sac/val dose at index. Prior dose of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker had only minor impact on first sac/val dose, compliance and persistence. CONCLUSIONS: Most patients prescribed sac/val are not initiated on the recommended dose nor up-titrated as recommended by the EU Summary of Product Characteristics. Initiation of sac/val was associated with high persistence and compliance and a dose reduction of diuretics. Barriers to up-titration must be explored.
