This 12-week, multicenter, randomized, double-blinded, 4-arm study in 440 patients with moderate to severe hypertension compared ambulatory blood pressure (ABP) responses with a triple-combination regimen (olmesartan medoxomil [OM] 40 mg, amlodipine besylate [AML] 10 mg, and hydrochlorothiazide [HCTZ] 25 mg) and its component dual-combination regimens at similar doses. At week 12, the triple combination resulted in a greater reduction in mean 24-hour systolic and diastolic blood pressure (-30.3/-18.0 mm Hg) compared with the 3 dual-combination regimens (OM 40 mg/AML 10 mg: -23.5/-13.9, OM 40 mg/HCTZ 25 mg: -23.9/-14.5, and AML 10 mg/HCTZ 25 mg: -18.5 mm Hg/-10.7 mm Hg; P<.0001 each). Greater efficacy was also found during daytime and nighttime hours and during the last 6, 4, or 2 hours of the dosing interval. The authors conclude that the triple combination of OM 40 mg/AML 10 mg/HCTZ 25 mg demonstrated superior efficacy and sustained reductions in ABP compared with its dual-combination components.
