Most patients with hypertension and diabetes require two or more antihypertensive agents to achieve the recommended blood pressure (BP) goal of <130/80 mm Hg. This prespecified subgroup analysis from the TRIple Therapy with Olmesartan Medoxomil, Amlodipine, and Hydrochlorothiazide in HyperteNsIve PatienTs StudY assessed the efficacy and safety of triple-combination treatment (olmesartan medoxomil 40/amlodipine besylate 10/hydrochlorothiazide 25 mg) versus the component dual-combination treatments according to diabetes status (diabetes; non-diabetes).Participants received dual-combination treatment for 4 weeks or placebo for 2 weeks. Participants receiving placebo switched to dual-combination treatment from week 2 to week 4. At week 4, participants switched to triple-combination treatment or continued on dual-combination treatment until week 12.The prespecified changes in BP from baseline for the diabetes subgroup receiving triple-combination treatment were greater than the respective dual-combination treatments (P ≤ .0013). Also, more participants with diabetes receiving triple-combination treatment reached BP goal (<130/80 mm Hg) versus those receiving dual-combination treatments (P ≤ .0092). In a post hoc analysis, significantly greater proportions of study participants with diabetes achieved BP targets with triple-combination treatment compared with each dual-combination treatment. Most treatment-emergent adverse events were mild to moderate in severity.In participants with hypertension and diabetes, triple-combination treatment led to greater BP reductions and enabled greater proportions of participants to reach BP goal versus the dual-combination treatments. Triple-combination treatment was well tolerated in both diabetes and non-diabetes subgroups.
