摘要
Previously, we reported the efficacy of aliskiren/amlodipine in US minority adults with stage 2 hypertension, with additional blood pressure (BP) lowering from the addition of hydrochlorothiazide (HCTZ). A subgroup analysis in patients with hypertension and comorbidities of diabetes, cardiometabolic syndrome, or obesity, and in black participants is reported. This 8-week, multicenter, double-blind study included 412 self-identified minority patients with mean sitting systolic BP (msSBP) %26gt;= 160 mm Hg and %26lt;200 mm Hg). Patients were randomized to receive either combination aliskiren/amlodipine 150/5 mg or amlodipine 5 mg. Doses were forced-titrated to a maximum of aliskiren/amlodipine/HCTZ 300/10/25 mg or aliskiren/amlodipine 300/10 mg, respectively. There were 256 black (62%), 118 diabetic (29%), 284 cardiometabolic syndrome (69%), and 249 obese (60%) randomized patients. Baseline msSBP was similar to 167 mm Hg across all subgroups. Least-square mean reductions in msSBP, the primary efficacy outcome, from baseline to week 8 across all subgroups, ranged from 35 to 37 mm Hg with aliskiren/amlodipine/HCTZ and 28 to 30 mm Hg with aliskiren/amlodipine (P %26lt; .01 for all between-treatment comparisons). Both regimens were well tolerated. Among high-risk patients, such as diabetics or those with cardiometabolic syndrome, combination aliskiren/amlodipine is effective in lowering BP; the addition of HCTZ provided incremental BP-lowering efficacy while maintaining tolerability. However, because our subgroups were not mutually exclusive, the generalization of our findings to the population seen in clinical practice is limited. J Am Soc Hypertens 2012;6(3):219-227.
