This is an interventional treatment trial for Hypertension Read More

Inclusion Criteria:

• Mild-to-moderate essential hypertension defined as a mean seated diastolic blood pressure measurement of ≥ 95 mmHg measured by manual cuff sphygmomanometer, on Visit 2 of the four-week placebo run-in period (baseline)
• Mean seated systolic blood pressure ≥ 140 mmHg, measured by manual cuff at baseline (Visit 2)
• A 24-hour mean diastolic blood pressure , measured by ABPM, of ≥ 85 mmHg evaluated at baseline (Visit 3)
• Age 18 or older
• Patient's written informed consent in accordance with GCP (Good Clinical Practice) and local legislation

Exclusion Criteria:

• Pre-menopausal women (last menstruation ≤ 1 year prior to date of consent):

  • Who are not surgically sterile (hysterectomy, tubal ligation)

  • Who have a positive urine pregnancy test
  • Who are nursing
• Mean seated diastolic blood pressure (DBP) > 114 mmHg or mean seated systolic BP > 200 mmHg, by manual cuff

• Any known hepatic and/or renal dysfunction as defined by the following laboratory parameters:

  • SGPT (serum glutamate pyruvate transaminase) (ALT) or SGOT (serum glutamate oxaloacetate transaminase) (AST) greater than two times the upper limit of normal
  • Serum creatinine > 1.8 mg/dl (or 159 µmol/l)
• Clinically relevant hypokalemia
• Known or suspected secondary hypertension
• Known bilateral renal artery stenosis; renal artery stenosis in a solitary kidney; post-renal transplant patients, presence of only one functioning kidney.
• Congestive heart failure (CHF) (NYHA (New York Heart Association) class CHF III-IV)
• Unstable angina within the past 3 months; stable angina where a change in nitrate therapy (dose or frequency) during the run-in period was required
• Stroke within the past 6 months prior to start of run-in period
• Myocardial infarction or cardiac surgery within the past 3 months prior to start of run-in period
• PTCA (percutaneous transluminal coronary angioplasty) within the past 3 months prior to start of run-in period
• Previous history of angioedema
• Sustained ventricular tachycardia, atrial fibrillation, atrial flutter or other clinically relevant cardiac arrhythmias as determined by the investigator
• Hypertrophic obstructive cardiomyopathy, hemodynamically relevant stenosis of the aortic or mitral valve
• Patients with unstable insulin-dependent diabetes mellitus (risk of hypoglycemia or HbA1c ≥ 10 % in history within 6 months prior to start of run-in period)
• Known drug or alcohol dependency within the past 6 months period prior to start of run-in period
• Concomitant administration of medications known to affect blood pressure, except medications allowed by the protocol
• Patients receiving any investigational therapy within one month of signing the informed consent form
• Known hypersensitivity to any component of the formulations
• Any clinical condition which, in the opinion of the investigator, would not allow safe completion of the protocol and safe administration of trial medication
• Concomitant use of lithium or cholestyramine or colestipol resins (potential drug interactions with HCTZ)
