The Effects on Blood Pressure Control, Pulse Wave Velocity, as Well as Safety and Tolerability of Felodipine Sustained Release in Chinese Patients.
A Randomized, Open-label Study to Evaluate the Effects on Blood Pressure Control, Pulse Wave Velocity, as Well as Safety and Tolerability of Felodipine Sustained Release, Alone and in Combination With Metoprolol, Lisinopril or Hydrochlorothiazide, in Chinese Patients With Mild to Moderate Essential Hypertension.

Detailed Description
In this study, investigators will choose male and female subjects aged between 35 and 79 years old with mild to moderate essential hypertension. At first 2 weeks, all patients will use felodipine 5mg daily. If the blood pressure dosen't meet the target (140/90mmHg), they will be randomized into metoprolol, lisinopril or hydrochlorothiazide combination groups for another 4 weeks therapy. After that, if the blood pressure has still not met the target, up-titrate the felodipine into 10mg, followed by a 4 weeks therapy. And if the blood pressure is still not met the target after that, up-titrate the combine drugs into maximum dosage. The whole treatment duration is 14 weeks.
The primary outcome is to evaluate the percentage of subjects reaching blood pressure target (defined as < 140 / 90 mmHg) after 14 weeks treatment with felodipine sustained release in combination with metoprolol, lisinopril or hydrochlorothiazide.

Description
Inclusion Criteria:
- Provision of written informed consent
- Female or male aged between 35-79 years old
Mild to moderate essential hypertension patients who meet any of the following criterias:
- Newly diagnosed, drug-naive, or without any antihypertension treatment for at least 3 months, moderate essential hypertension patients. (160mmHg mean SiSBP 180mmHg or 100mmHg mean SiDBP 110mmHg)
Newly diagnosed, drug-naive, or without any antihypertension treatment for at least 3 months, mild essential hypertension patients (140mmHg mean SiSBP 160mmHg or 90mmHg mean SiDBP 100mmHg) with high or extreme high cardiovascular risk (a)(having 3 or more than 3 risk factors and/or target organ lesion and/or diabetes mellitus).
(a) according to Chinese guideline for prevention and treatment of patients with hypertension 2004.
The patients have already received starting dosage of single anti-hypertension drug therapy (exclude the drugs containing felodipine component ), however the blood pressure is not well controlled (140mmHg mean SiSBP 160mmHg or 90mmHg mean SiDBP 100mmHg). After stopping the drug for 5 eliminating half life time, the patients meet any one of the following two:
- 160mmHg mean SiSBP 180mmHg or 100mmHg mean SiDBP 110mmHg.
- 140mmHg mean SiSBP 160mmHg or 90mmHg mean SiDBP 100mmHg) with high or extreme high cardiovascular risk* (having 3 or more than 3 risk factors and/or target organ lesion and/or diabetes mellitus).
Sitting blood pressure is taken after subjects take a seat to rest for 5 minutes before the next medication.
Exclusion Criteria:
Any of the following is regarded as a criterion for exclusion from the study:
- Known or suspected secondary hypertension

- Atrioventricular block of first degree (with P-R>0.24seconds), or second or third degree
- Other clinical significant arrhythmia
- Unstable and/or decompensated congestive heart failure
- Angina, acute myocardial infarction, percutaneous coronary intervention (PCI), or cardiac surgery
- Asthma or moderate to severe chronic obstructive pulmonary disease
- Type 1 diabetes mellitus
- Gout history
- Fasting serum glucose of greater than 200 mg/dl (11.1 mmol/L) or type 2 diabetes mellitus needs insulin therapy
- ALT>3ULN
- Cr>1.5mg/dl
- Pregnancy or lactation.
- Alcohol or drug abuse
- Known need for other concomitant anti-hypertensive therapy during the study besides the study drug.
- Known or suspected allergy to investigational drug or non-active ingredients of investigational drugs, known allergy to other blockers, calcium antagonist, diuretics, angiotensin converting enzyme inhibitor or with other contraindications.
- Suspected white-coat hypertension based on investigator's judgement.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Felodipine tablet (Plendil)
|
Felodipine sustained release tablet single drug therapy (1st week- 2nd week) Eligible subjects will first take felodipine tablet 5mg, once daily, orally for 2 weeks.
If blood pressure is controlled after 2 weeks, then the subjects will continue the treatment until the end of primary therapy stage (14th week).
|
Active Comparator: Felodipine tablet (Plendil)+Metoprolol tablet (Betaloc ZOK)
|
Step 1: Eligible subjects will first take felodipine tablet 5mg, once daily, orally for 2 weeks. If blood pressure is not controlled after 2 weeks, then the subjects will go to Step 2: Felodipine sustained release tablet 5mg once daily combined with metoprolol succinate prolonged-release tablet (Betaloc ZOK) 47.5mg , once daily. If blood pressure is not controlled after 4 weeks, then the subjects will go to Step 3: The dosage of felodipine sustained release tablet will be escalated to 10mg, once daily, while the dosage of the combined drug remains the same. If blood pressure is not controlled after 4 weeks, then the subjects will go to Step 4: The dosage of felodipine sustained release tablet keeps 10mg, once daily, while the dosage of different combined drug is doubled. |
Active Comparator: Felodipine tablets (Plendil)+Lisinopril (Zestril)
|
Step 1: Eligible subjects will first take felodipine tablet 5mg, once daily, orally for 2 weeks. If blood pressure is not controlled after 2 weeks, then the subjects will go to Step 2: Felodipine sustained release tablet 5mg once daily combined with Lisinopril (Zestril) 10mg, once daily. If blood pressure is not controlled after 4 weeks, then the subjects will go to Step 3: The dosage of felodipine sustained release tablet will be escalated to 10mg, once daily, while the dosage of the combined drug remains the same. If blood pressure is not controlled after 4 weeks, then the subjects will go to Step 4: The dosage of felodipine sustained release tablet keeps 10mg, once daily, while the dosage of different combined drug is doubled. |
Active Comparator: Felodipine tablet (Plendil)+Hydrochlorothiazide
|
Step 1: Eligible subjects will first take felodipine tablet 5mg, once daily, orally for 2 weeks. If blood pressure is not controlled after 2 weeks, then the subjects will go to Step 2: Felodipine sustained release tablet 5mg once daily combined with hydrochlorothiazide 12.5mg, once daily. If blood pressure is not controlled after 4 weeks, then the subjects will go to Step 3: The dosage of felodipine sustained release tablet will be escalated to 10mg, once daily, while the dosage of the combined drug remains the same. If blood pressure is not controlled after 4 weeks, then the subjects will go to Step 4: The dosage of felodipine sustained release tablet keeps 10mg, once daily, while the dosage of different combined drug is doubled. |
