Abstract

This previously unpublished, preplanned analysis investigated the efficacy of the olmesartan/amlodipine combination at different doses on 24-h blood pressure (BP) control, as well as assessed trough estimation of trough-to-peak ratio (TPR) and smoothness index (SI). Ambulatory BP monitoring was performed in patients with moderate-to-severe hypertension whose BP was inadequately controlled after 8 weeks’ treatment with amlodipine 5 mg. Patients were randomized to continue with amlodipine 5mg or to receive olmesartan/amlodipine 10/5, 20/5 or 40/5 mg for 8 weeks (Period II). Patients not achieving BP control were uptitrated to a more powerful regimen for another 8 weeks (Period III). During Period II, each olmesartan/ amlodipine combination reduced 24-h systolic and diastolic BP (SBP/DBP), as well as morning and early morning SBP/DBP, significantly more than amlodipine 5mg (Po0.001 for all). TPRs were higher in each olmesartan/amlodipine group than with amlodipine 5 mg, and SI values showed dose-related increases; olmesartan/amlodipine 40/5 mg produced a significantly higher SI for SBP and DBP (1.55 and 1.33, respectively) than amlodipine 5mg (0.96 and 0.77, respectively, Po0.0001 for each). During Period III, uptitrated patients showed further BP reductions, which were largest in those on olmesartan/amlodipine 40/10 mg. SI values increased in uptitrated patients and were highest with olmesartan/amlodipine 40/10mg (SBP 1.62/DBP 1.41). The olmesartan/amlodipine combination effectively reduces BP over 24 h, including the morning hours, in a dose-related manner. Compared with amlodipine alone, the olmesartan/amlodipine combination has a better 24-h coverage (TPR) and a dose-related improvement in BP lowering homogeneity (SI).
