Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
2. Medicine: spironolactone (20mg/tablet), indapamide (1.5mg/tablet) and amlodipine (5mg/tablet).
3. Rationale: Our hypothesis of the present trial is that spironolactone is superior to indapamide in cardiovascular prevention in hypertensive patients, with the possible addition of amlodipine. Before a clinical outcome trial is considered, the present feasibility trial is designed to compare the efficacy of antihypertensive regimens based on these two drugs on blood pressure and several measurements of organ damage.
4. Objective: To evaluate the effects of spironolactone (either with or without amlodipine), in comparison with indapamide (either with or without amlodipine), on the extent of blood pressure reduction.
5. Study design: Multi-center (five sites), prospective, randomized, open-label, blinded-end point study with active treatment arm (study duration - 12 weeks)
6. Study population: Men and Women aged over 45 years (n=200) meeting the inclusion/exclusion criteria.
7. Randomization and treatment: After stratification by centers, eligible patients will be randomly divided into two groups, taking spironolactone (20mg tablet) once a day or indapamide (1.5mg tablet) once a day. Spironolactone may be up-titrated to 40mg daily and indapamide may be up-titrated to 3mg daily at 4-week or 8-week visit. At 8-week visit, if needed, we will add amlodipine at 5 or 10 mg once daily.
8. Follow up: 12 weeks.
9. Sample size: a total of 200 patients should be enrolled in the combination.
10. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in June 2020, recruitment will start. Patients enrollment will be performed between June 2020 to November 2020. All patients should be followed up before July 2021.

6. Study population: Men and Women aged over 45 years (n=200) meeting the inclusion/exclusion criteria. Adult subjects with essential hypertension will be included. Specific criteria are as follows:
Male and female subjects participates (OK with more women is preferred) Age ≥45 years Clinic systolic BP: 140 -179 mmHg (untreated or on monotherapy treatment) Waist Circumference (WC) ≥90 cm for male and ≥85 cm for female
7. Randomization and treatment: After stratification by centers, eligible patients will be randomly divided into two groups, taking spironolactone (20mg tablet) once a day or indapamide (1.5mg tablet) once a day. Spironolactone may be up-titrated to 40mg daily and indapamide may be up-titrated to 3mg daily at 4-week or 8-week visit. At 8-week visit, if needed, we will add amlodipine at 5 or 10 mg once daily.
8. Follow up: 12 weeks. Patients will be followed up every 4 weeks. Ambulatory and office blood pressure will be measured. Medical history should be recorded. Clinical examinations including blood biochemical tests (serum creatinine, uric acid and electrolytes) should be performed.
9. Sample size: a total of 200 patients should be enrolled in the combination.
10. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in June 2020, recruitment will start. Patients enrollment will be performed between June 2020 to November 2020. All patients should be followed up before July 2021.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
1. Male and post menopause female subjects participates (OK with more women is preferred)
2. Age ≥45 years
3. Clinic systolic BP: 140 -179 mmHg (untreated or on monotherapy treatment)
4. Waist Circumference (WC) ≥90 cm for male and ≥85 cm for female
Exclusion Criteria
2. Hyperkalemia (serum potassium concentration ≥5.0 mmol/L) or hypokalemia (serum potassium concentration ≤3.5 mmol/L)
3. Contraindication for the treatment drugs or current use of spironolactone, indapamide or amlodipine
4. Chronic kidney disease (eGFR≤45 ml/min 1.73 m² or serum creatinine ≥ 2 mg/dl)
5. Expected lifespan ≤6 months
6. Treated subjects in whom withdrawal of antihypertensive treatment is deemed unethical by the investigator (e.g. because of the existence of compelling indications other than hypertension for continuous use of previously used antihypertensive agent)
7. Contraindications to study treatments as detailed in the relative Summaries of medical Product Characteristics for spironolactone, indapamide or amlodipine (this includes hypersensitivity, pregnancy and lactation)
8. Diagnosed cardiovascular diseases other than hypertension (coronary heart disease, heart failure or left ventricular systolic dysfunction of any degree, atrial fibrillation or frequent arrhythmias, valvular or congenital heart disease, cardiomyopathies, cerebrovascular disease, peripheral artery disease, or aortic aneurysm)
9. Subjects with conditions other than those mentioned above, where compelling indications for the use of any specific class of antihypertensive medication exist, according to the current (e.g. European Society of Cardiology) guidelines
10. Other conditions deemed relevant by the investigator (including respiratory disorders, liver disease, renal disease, thyroid disorders)
