An Examination of the Blood Pressure Lowering Ability and Safety of Olmesartan Medoxomil in Elderly Patients With Hypertension

A Prospective, Open Label, Single Arm Study to Evaluation the Safety and Efficacy of an Olmesartan Medoxomil Based Treatment Regimen in Elderly Patients With Hypertension

This 14 week study will examine the ability of olmesartan medoxomil to lower the blood pressure of patients 65 years of age or older with high blood pressure. The medication being tested has been approved by the FDA for the treatment of high blood pressure.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Mean 24-hour Ambulatory Systolic Blood Pressure After 12 Weeks of Active Treatment	All participants started the treatment arm with 20 mg olmesartan medoxomil (Olm). If their blood pressure was not controlled, participants were titrated at 3-week intervals to: Olm 40 mg, then, if needed Olm 40 mg + hydrochlorothiazide (HCTZ) 12.5 mg, then, if needed Olm 40 mg + HCTZ 25 mg This outcome measure included all participants at the end of the 12-week treatment period regardless of whether or not they were titrated. They had to have both baseline and 12-week ambulatory blood pressure measurements.	baseline to 12 weeks

Secondary Outcome Measures
