Abstract
In a prespecified subgroup analysis of a 12-week multinational, randomized, double-blind, parallel-group trial, self-identified Hispanic/Latino adult men and women with systolic blood pressure 160 mm Hg to 179 mm Hg received combination aliskiren/hydrochlorothiazide (HCT) 150/12.5 mg or aliskiren 150 mg (force-titrated to 300/25 mg and 300 mg, respectively, at week 1). At week 12, combination aliskiren/HCT provided greater reduction in mean sitting systolic blood pressure from baseline, the primary efficacy variable, compared with aliskiren monotherapy (-32.6 mm Hg vs -19.6 mm Hg; P<.0001). Differences in mean sitting diastolic blood pressure reductions followed a similar pattern (-13.5 mm Hg vs -7.1 mm Hg; P<.0001). Notable blood pressure reductions were evident at week 1 in both treatment groups, with near-maximal effects reached by week 8. Results were consistent regardless of country of residence. Both treatments were well tolerated. Aliskiren alone or in combination with HCT is safe and effective in Hispanic/Latino patients with stage 2 hypertension. Combination aliskiren/HCT produced greater blood pressure reductions than aliskiren monotherapy.
