Brief summary

This is a multicentre, randomized, open-label parallel trial to demonstrate the superiority and/or non-inferiority of bisoprolol on metoprolol succinate sustained-release (SR) tablet in subjects with mild to moderate primary hypertension.

Detailed description

Primary objectives: To demonstrate that bisoprolol is superior in mean ambulatory heart rate and/or non-inferior in mean ambulatory DBP as compared with metoprolol SR in the last 4 hours after 12-week active treatment in subjects with mild to moderate essential hypertension (EH). Secondary objectives: 1. To compare the efficacy of the 2 study drugs by 24h ambulatory monitoring by several parameters at different times (Example: blood pressure, heart rate, their variability, etc...) after 12-week treatment from baseline among subjects with mild to moderate EH 2. To evaluate safety of the two drugs 3. To evaluate the treatment compliance of the two drugs

Interventions

DRUGBisoprolol

Subjects will receive bisoprolol fumarate (Concor®) at a dose of 5 milligram (mg) once daily orally as sustained release (SR) tablets for a period of 4 weeks. The dose of bisoprolol will be escalated to 7.5 mg orally once daily for next 4 weeks (Weeks 4 to 8) and to 10 mg orally once daily for the next 4 weeks (Weeks 8 to 12), if clinic systolic blood pressure (SBP) was greater than or equal to (\>=) 140 millimeters of mercury (mmHg) and/or diastolic blood pressure (DBP) was \>=90 mmHg measured every 4 weeks.

DRUGMetoprolol

Subjects will receive metoprolol succinate (Betaloc SR) at a dose of 47.5 mg once daily orally as SR tablets for a period of 4 weeks. The dose of metoprolol will be escalated to 71.25 mg orally once daily for next 4 weeks (Weeks 4 to 8) and to 95 mg orally once daily for the next 4 weeks (Weeks 8 to 12) if clinic SBP was \>=140 mmHg and/or DBP was \>=90 mmHg measured every 4 weeks.

Heart Rate Response Rate

Heart rate response was defined as decrease in heart rate from baseline \>=10 percent (%). Heart rate response rate was calculated by using the number of subjects with heart rate response divided by total number of subjects and multiplied by 100.

Time frame: Week 12

Population: ITT analysis population included all randomized subjects. 'N' (number of subjects analyzed) signifies number of evaluable subjects for this outcome measure.
