Brief Summary
Previous studies have shown that elevated nighttime blood pressure (BP) was more closely associated with cardiovascular mortality and morbidity than daytime and clinic BPs. With increasingly advanced technology, not only 24-hour ambulatory but also home BP monitors can be used to evaluate nighttime BP. The validation study of the Omron HEM 9601T showed that the wrist-type home BP monitor could be a suitable and reliable tool for the diagnosis and management of nocturnal hypertension. However, up to now, there is no data on home nighttime BP in Chinese patients and it is unclear if different dosing time would reduce ambulatory and home nighttime BPs differently. The investigators therefore designed a multicenter randomized clinical trial to compare between morning dosing and bedtime dosing of antihypertensive medications in the difference in nighttime, daytime and the 24-h BP reductions evaluated by both ambulatory and home BP monitoring, and in target organ protections.

Study Arms (2)
The morning dosing group
ACTIVE COMPARATORAfter randomization, subjects will take alisartan 120 mg (Salubris, Shenzhen, China) once daily at 6:00-10:00. After 8 weeks of treatment, if the 24-hour ambulatory systolic BP remained ≥ 130 mmHg, alisartan will be doubled to 240mg. After 16 weeks of treatment, if the 24-hour ambulatory systolic BP remained ≥ 130 mmHg, amlodipine besylate 2.5 mg (Dawnrays, Suzhou, China) once daily will be added. The whole treatment duration will last for 24 weeks.
The bedtime dosing group
EXPERIMENTALAfter randomization, subjects will take alisartan 120 mg once daily at 20:00-24:00. The follow-up plan is the same as the morning dosing group.
Interventions
Drugs will be taken once daily at 6:00-10:00.
Eligibility Criteria
You may qualify if:
- Male or female patients aged 18-70 years old;
- Never treated for hypertension or stopped using antihypertensive drugs for at least 2 weeks;
- In the two screenings,the clinical systolic BP should be in the range of 140-159 mmHg, the diastolic BP \< 100 mmHg;
