Abstract

Background: Treatment guidelines recommend combination therapy to control blood pressure (BP) in the majority of hypertensive patients. This longterm open-label study assessed a treatment algorithm based on olmesartan medoxomil (hereafter olmesartan), amlodipine and hydrochlorothiazide (HCTZ). Methods: Patients with moderate-to-severe hypertension who were inadequately controlled with amlodipine 5mg/day monotherapy and who subsequently completed 16 weeks of double-blind combination treatment with olmesartan and amlodipine entered a 28-week open-label phase in which all patients initially received olmesartan/amlodipine 40/5mg/day. After 4, 10 and 19 weeks, patients with inadequately controlled hypertension (seated trough diastolic [DBP] and systolic [SBP] BP ≥ 90mmHg and ≥140 mmHg, respectively) had their doses increased in a step-wise manner to: (i) olmesartan/ amlodipine 40/10 mg; (ii) olmesartan/amlodipine/HCTZ 40/10/12.5 mg; and (iii) olmesartan/amlodipine/HCTZ 40/10/25 mg. Results: In total, 692 patients entered the open-label phase (691 on olmesartan/ amlodipine 40/5 mg). The majority of patients remained on olmesartan/ amlodipine 40/5mg without dose elevation, and, of these, 74.3% achieved goal BP at study completion or early termination. Additional patients achieved goal BP with each successive uptitration of therapy: in patients who finished the study on olmesartan/amlodipine 40/10mg and olmesartan/ amlodipine/HCTZ 40/10/12.5mg, the respective proportions who reached goal BP were 59.0% and 47.1%. Overall, 66.9% of patients achieved the European guideline recommended goal BP of SBP > 140mmHg and DBP > 90mmHg for patients without diabetes mellitus, and SBP > 130mmHg and DBP
