Primary Outcome Measures:
  • Change of mean ambulatory diastolic blood pressure in the last 4 hours after 12-week treatment from baseline (i.e. △DBP) [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]
  • Change of mean heart rate in the last 4 hours after 12-week treatment from baseline (i.e.△HR) [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change of mean ambulatory systolic blood pressure baseline in the last 4 h (i.e. △SBP) [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]
  • Change of mean ambulatory 24-h blood pressure [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]
  • Change of mean ambulatory daytime blood pressure [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]
  • Change of mean ambulatory night-time blood pressure [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]
  • Change of mean ambulatory daytime heart rate [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]
  • Change of mean ambulatory night-time heart rate [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]
  • 24-hour variability of blood pressure [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • The response rates for blood pressure [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    DBP≤90 mmHg or a DBP reduction ≥10 mmHg from baseline

  • The response rates for heart rate [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    10% HR reduction from baseline

  • Change of mean ambulatory 24-h heart rate [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Bisoprolol Group
Concor 5mg, oral
Drug: Bisoprolol

Dose escalation schedule: 5mg 1/d to 7.5mg 1/d to 10mg 1/d.

The active drug should be taken as close to 8am every morning. Every 4 weeks the dosage need to be up-titrated if the patient's blood pressure (BP) is ≥140 and/or 90mmHg. The first Ambulatory blood pressure monitoring (ABPM) is performed on the last day of the wash-out period. The second ABPM is performed on the last day of the active treatment.

Other Name: Concor
Active Comparator: Metoprolol SR Group
Betaloc ZOK 47.5mg, oral
Drug: Metoprolol

Dose escalation schedule: 47.5mg 1/d to 71.25mg 1/d to 95mg 1/d.

Comparison of different drug. Metoprolol succinate 47.5mg/tablet, oral


Detailed Description:

Primary objectives:

To demonstrate that bisoprolol is superior in mean ambulatory heart rate and/or non-inferior in mean ambulatory diastolic blood pressure as compared with metoprolol SR in the last 4 hours after 12-week active treatment in patients with mild to moderate essential hypertension.

Secondary objectives:

  1. To compare the efficacy of the 2 study drugs by 24h ambulatory monitoring by several parameters at different times (e.g. blood pressure, heart rate, their variability, etc...) after 12-week treatment from baseline among patients with mild to moderate essential hypertension
  2. To evaluate the safety of these two study drugs
  3. To evaluate the compliance of the two study drugs
