Aliskiren-based stepped-care treatment algorithm provides effective blood pressure control.

AIMS

Recent guidelines for the management of hypertension recommend an individualised stepped-care treatment approach in mild-to-moderate hypertensive patients, to achieve blood pressure (BP) goals. This study evaluated the probability of patients achieving BP targets with an aliskiren-based stepped-care treatment regimen.

METHODS

This was a 24-week, open-label, non-comparator study design that included six sequential 4-week treatment periods in patients with mild-to-moderate hypertension. Over the potential 24 weeks of active treatment, incremental therapy included the following add-on therapies at 4-week intervals: aliskiren 150-300 mg once daily, hydrochlorothiazide (HCTZ) 12.5-25 mg once daily, and finally amlodipine 5-10 mg once daily, as needed to achieve target BP. Subjects achieving BP targets following any given 4 weeks of therapy were considered study completers, while subjects not achieving their clinical BP target entered into the next step of incremental therapy. The primary efficacy end-point was the estimated cumulative probability of patients achieving BP target.

RESULTS

Of 256 patients treated, 232 (90.6%) completed the study. Baseline mean sitting BP was 155.7/91.7 mmHg. At study end-point, the estimated cumulative probability of reaching BP target was 86.12%. The stepped-care treatment regimen was well tolerated at the maximal recommended doses of all the individual complimentary therapies.

CONCLUSION

An aliskiren-based stepped-care treatment regimen that subsequently included both HCTZ and amlodipine is effective in achieving BP goals in approximately 90% of patients with mild-to-moderate hypertension.
