Study Details
Study Description
Brief Summary
This is a Phase 4, prospective, multi-centric and randomized controlled study to compare the effects of bisoprolol and atenolol on resting heart rate (RHR) and sympathetic nervous system's (SNS) activity in subjects with essential hypertension.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Bisoprolol
|
Drug: Bisoprolol
Bisoprolol will be administered at a dose of 5 milligram (mg) once daily for 2 weeks. If heart rate is less than or equal to 65 beats per minute (bpm), then the initial dose will be administered for another 2 weeks. If the heart rate remains greater than 65 bpm, then the dose will be further increased to 7.5 mg once daily for 2 weeks. After 2 weeks, if the heart rate is less than or equal to 65 bpm, the increased dose will be administered for another 2 weeks. If the heart rate is still greater than 65 bpm, then the dose will be further increased to 10 mg once daily for 2 weeks. After 2 weeks, if the heart rate is less than or equal to 65 bpm, the increased dose will be administered for another 2 weeks.
Other Names:

Active Comparator: Atenolol
|
Drug: Atenolol
Atenolol will be administered at a dose of 50 mg once daily for 2 weeks. If heart rate is less than or equal to 65 bpm, then the initial dose will be administered for another 2 weeks. If the heart rate remains greater than 65 bpm, then the dose will be further increased to 75 mg once daily for 2 weeks. After 2 weeks, if the heart rate is less than or equal to 65 bpm, the increased dose will be administered for another 2 weeks. If the heart rate still greater than 65 bpm, then the dose will be further increased to 100 mg once daily for 2 weeks. After 2 weeks, If the heart rate is less than or equal to 65 bpm, the increased dose will be administered for another 2 weeks.

Outcome Measures
Primary Outcome Measures
- Change From Baseline in Baroreflex Sensitivity (BRS) at Attainment of Heart Rate Goal [Baseline and attainment of heart rate goal (Week 2 or Week 4 or Week 6)]
Baroreflex sensitivity (BRS) is an important characteristic of baroreflex control and often noninvasively assessed by relating heart rate (HR) fluctuations to blood pressure (BP) fluctuations. Heart rate goal was defined as attainment of heart rate less than or equal to 65 beats per minute (bpm).
- Change From Baseline in Baroreflex Sensitivity (BRS) at End of Follow-up [Baseline and end of follow-up (Week 4 or Week 6 or Week 8)]
Baroreflex sensitivity (BRS) is an important characteristic of baroreflex control and often noninvasively assessed by relating heart rate (HR) fluctuations to blood pressure (BP) fluctuations. Heart rate goal was defined as attainment of heart rate less than or equal to 65 bpm.
Secondary Outcome Measures
- Change From Baseline in Heart Rate Variability (HRV) for Low Frequency Power (LF) and for High Frequency Power (HF) at Attainment of Heart Rate Goal and End of Follow-up [Baseline, attainment of heart rate goal (Week 2 or Week 4 or Week 6) and end of follow-up (Week 4 or Week 6 or Week 8)]
Heart rate variability (HRV) is used to describe the variations of both instantaneous HR and resting rate (RR) intervals and was evaluated for low frequency power (LF) and for high frequency power (HF). Heart rate goal was defined as attainment of heart rate less than or equal to 65 bpm.
- Change From Baseline in Ratio of Heart Rate Variability (HRV) for Low Frequency Power (LF) to Heart Rate Variability Power (HRV) for High Frequency (HF) (LF/HF) at Attainment of Heart Rate Goal and End of Follow-up [Baseline, attainment of heart rate goal (Week 2 or Week 4 or Week 6) and end of follow-up (Week 4 or Week 6 or Week 8)]
Heart rate variability (HRV) is used to describe the variations of both instantaneous HR and resting rate (RR) intervals and was evaluated for low frequency power (LF) and for high frequency power (HF). Heart rate goal was defined as attainment of heart rate less than or equal to 65 bpm.
- Number of Participants Attaining Heart Rate Goal at Dosage 1, 2 and 3 of Study Treatment [Baseline up to attainment of heart rate goal (Week 2 or Week 4 or Week 6)]
Dosage 1, 2 and 3 for bisoprolol group was defined as 5 mg, 7.5 mg and 10 mg once daily and for atenolol group as 50 mg, 75 mg and 100 mg once daily, respectively. Heart rate goal was defined as attainment of heart rate less than or equal to 65 bpm.

Heart rate goal was defined as attainment of heart rate less than or equal to 65 bpm.
- Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [Baseline up to end of follow-up (Week 4 or Week 6 or Week 8)]
AE: any new untoward medical occurrence/worsening of pre-existing medical condition, whether or not related to study drug. SAE: Any AE that resulted in death; was life threatening; resulted in persistent/significant disability/incapacity; resulted in/prolonged an existing in-patient hospitalization; was a congenital anomaly/birth defect; or was a medically important condition
