The primary objective of this study was to assess the anti-hypertensive effect of OM/HCTZ 40/12.5 mg combination therapy compared to OM 40 mg monotherapy in lowering sitting diastolic BP in hypertensive patients after 8 weeks of double-blind treatment.
The study consisted of two sequential phases of 8 weeks duration each:
During the first phase, OM 40 mg monotherapy was compared with OM/HCTZ 40/12.5 mg in order to evaluate the additional benefit of OM/HCTZ 40/12.5 mg in the treatment of essential moderate to severe hypertension.
During the second phase, patients whose BP proved to be insufficiently controlled by the OM 40 mg monotherapy were to start OM/HCTZ 40/12.5 mg combination therapy while patients whose BP proved to be insufficiently controlled by the OM/HCTZ 40/12.5 mg combination were to be up-titrated to the OM/HCTZ 40/25 mg combination to evaluate the additional benefit of the up-titrated combination.
The study was be conducted by qualified and experienced personnel with adherence to GCP, current guidelines on the design of studies in hypertension, the applicable regulatory requirements and the ethical principles based on the Declaration of Helsinki.

Active Comparator: OM 40
Olmesartanmedoxomil (OM)40 mg tablets.
Drug: OM 40
Initially patients were to be treated with Olmesartanmedoxomil (OM)40 mg tablets once daily for 8 weeks. After 8 weeks non-responders were to be uptitrated to OM/HCTZ 40/12.5 mg and responders remained on the previous therapy for further 8 weeks.
Experimental: OM/HCTZ 40/12.5
Olmesartanmedoxomil (OM) /Hydrochlorothiazide (HCTZ)40/12.5 mg tablets.
Drug: OM/HCTZ 40/12.5
Initially patients were to be treated with Olmesartanmedoxomil (OM) /Hydrochlorothiazide (HCTZ)40/12.5 mg tablets once daily for 8 weeks. After 8 weeks non-responders were to be uptitrated to OM/HCTZ 40/25 mg and responders remained on the previous therapy for further 8 weeks.
- Change in diastolic blood pressure. [ Time Frame: Between baseline and week 8 ]
- Change in diastolic blood pressure among non-responders to primary therapy. [ Time Frame: Between week 8 and week 16. ]
