Detailed Description
The study is designed as a multicenter, randomized, open-label, parallel-group and active controlled clinical study. The ratio of test group (lercanidipine group) and control group (felodipine group) is 1:1.
The study period lasts for 8 weeks, including 0-2 weeks of run-in period and 6 weeks of treatment period. There are 5 visits: run-in period (V1), baseline (V2), 2 weeks after treatment (V3), 4 weeks after treatment (V4) and 6 weeks after treatment (V5).
There are about 2 weeks for run-in period, the patients should start continuous recording the data of self-measuring blood pressure and heart rate for 1 week (at least 5days) before randomized in V2. Patients who under the antihypertensive treatment or have discontinued the antihypertensive treatment for less than 1 week need to discontinued the treatment for over 1week and start this trial; patients who never received any antihypertensive drug or patients who have discontinued the antihypertensive treatment for over one week will directly enter treatment period.
In V2, investigator should confirm the patient meet the inclusion/exclusion criteria, only the eligible patients will be divided groups by random, and the rest need to drop-out this trial. In that day of randomization, patients should take drug.
After the randomization, the patients will be given study drugs, and take take once-daily dose of the study drugs at 07:00-09:00 (except the day of visit). During the treatment, there will be a visit every 2 weeks, and in each visit the patients need to get the study drug for next two weeks, totally 3 times. In V3 and V4, if the patients' mean DBP ≥ 90 mm Hg, the doses will be doubled, twice a day (07:00- 09:00 in the morning and 16:00-18:00 in the afternoon), otherwise, the dosage do not change.
From the day beginning administration of the study drugs, patient should measure the BP and HR every day with the electronic sphygmomanometer after getting up in the morning and before going to bed. And patient records the data of blood pressure and heart rate in the record card. 2 to 3 minutes waiting for each measure and at least 12 significant date for consecutive 3 days. In every visit, investigator will collect the data of patient's self-measuring blood pressure, and give new recording forms for self-measuring blood pressure to the patients.
