Results of a new study found that the investigational triple combination therapy of olmesartan medoxomil (OM), amlodipine besylate (AML), and hydrochlorothiazide (HCTZ) demonstrated significantly greater mean reductions at week 12 in blood pressure (37.1/21.8 mm Hg versus 27.5 to 30.0/15.1-18.0 mm Hg LS Mean Reductions, P< 0.0001), as compared to corresponding dual combination therapy (dual components).
The study, presented at the American Society of Hypertension (ASH) annual meeting in New York, also found that at week 12, a significantly greater percentage of patients treated with the investigational triple combination therapy (OM/AML/HCTZ 40/10/25 mg) reached blood pressure goal (<140/90 mm Hg or <130/80 mm Hg for patients with diabetes, chronic renal disease, or chronic cardiovascular disease), as compared to corresponding dual components (64.3 percent versus 34.9 to 46.6 percent; P<0.0001, all comparisons). The triple therapy was well tolerated with most reported adverse events defined as mild or moderate.
"Many patients with hypertension fail to reach recommended blood pressure targets even when taking more than one therapy," said Suzanne Oparil, MD, Professor of Medicine and Physiology and Biophysics at the University of Alabama School of Medicine. "This study demonstrated that treating patients with a triple combination therapy regimen, each component which has a different mechanism of action, is more effective at lowering blood pressure than the dual combination of any two individual components and was well tolerated among the patients studied."
