Efficacy of olmesartan medoxomil and hydrochlorothiazide fixed-dose combination therapy in patients aged 65 years and older with stage 1 and 2 hypertension or isolated systolic hypertension.
Am J Cardiovasc Drugs. 2012 Oct 01; 12(5):325-33.AJ

Abstract

BACKGROUND

The incidence of hypertension, particularly isolated systolic hypertension, increases with increasing age, as does the risk of fatal cardiovascular disease. A combination antihypertensive therapy regimen may be required to reach recommended BP goals in older patients.

OBJECTIVES

This study set out to report blood pressure (BP) data in elderly patients across the subgroups of stage 1 and stage 2 hypertension (prespecified subgroup) and isolated systolic hypertension (ISH) [post hoc].

DESIGN AND SETTING

This was a subgroup analysis of a prospective, open-label study carried out in a multicenter, outpatient setting (e.g. the BeniSILVER [Benicar Efficacy: New Investigation Shows OM Treatment Increasingly Leads to Various Elderly Populations to Safe BP Reductions; ClinicalTrials.gov identifier: NCT00412932] study). The study included 176 patients with a mean age of approximately 72 years; stage 1 hypertension, 60, stage 2 hypertension, 116, and ISH, 98.

INTERVENTION

After a 2- to 3-week placebo run-in period, patients were uptitrated every 3 weeks from olmesartan medoxomil (OM) 20 mg daily to OM 40 mg, OM/hydrochlorothiazide (HCTZ) 40 mg/12.5 mg, and OM/HCTZ 40 mg/25 mg, if seated cuff BP (SeBP) was ≥120/70 mmHg.

MEASUREMENTS

Measurements included change from baseline in mean 24-hour ambulatory BP and SeBP after 12 weeks of treatment, percentage of patients achieving a cumulative SeBP goal of <140/90 mmHg (stage 1 and stage 2 cohorts) or seated cuff systolic BP (SeSBP) goal of <140 mmHg (ISH cohort), and the incidence of adverse events (AEs).

RESULTS

Combination therapy was required by 159 patients. Changes from baseline in mean 24-hour ambulatory BP (± standard deviation [SD]) were -24.2 (± 11.8)/-11.8 (± 6.9) mmHg, -26.5 (± 11.8)/-12.6 (± 6.7) mmHg, and -24.7 (± 12.5)/-11.2 (± 6.4) mmHg in the stage 1, stage 2, and ISH cohorts, respectively (all p < 0.001 vs baseline). Mean SeBP changes (± SD) from baseline in patients titrated to OM/HCTZ 40 mg/25 mg were -24.6 (± 11.4)/-10.5 (± 7.3) mmHg in the stage 1 cohort, -26.4 (± 17.2)/-11.3 (± 9.7) mmHg in the stage 2 cohort, and -21.5 (± 15.6)/-6.8 (± 7.8) mmHg in the ISH cohort (all p < 0.001). The cumulative proportions of patients achieving an SeBP goal of <140/90 mmHg by week 12 were 88.3%, 56.0%, and 72.4% in the stage 1, stage 2, and ISH cohorts, respectively, while 72.4% of patients achieved an SeSBP of <140 mmHg in the ISH cohort. Treatment-emergent AEs ranged from 32.3% to 32.8%, with <3% of patients reporting drug-related hypotension.

CONCLUSION

An OM/HCTZ-based titration regimen enabled elderly patients with hypertension to safely reduce BP throughout the 24-hour dosing interval and allowed the majority of these patients to achieve a BP target of <140/90 mmHg or <140 mmHg.
