Beschreibung
Inclusion Criteria:
- Mild-to-moderate hypertension as defined by a morning mean diastolic blood pressure from ≥ 90 and ≤ 115 mmHg and a mean systolic blood pressure ≤ 200 mmHg after five minutes in the seated position at the end of three weeks of placebo run-in treatment
- Male or female patients between 18 and 65 years of age, inclusive. Patients 60 to 65 years of age must have a screening 24-hour urine creatinine clearance rate of ≥ 1 mL/sec
- Ability to provide written informed consent
Exclusion Criteria:
- Pre-menopausal women (last menstruation ≤ one year to start of screening)
Post-menopausal women (last menstruation > one year from start of screening or have had a hysterectomy and oophorectomy)
- Who have < three months of stable estrogen replacement therapy at screening
- Who will be on progesterone therapy at any time during the trial
- Known or suspected secondary hypertension
Hepatic and/or renal dysfunction as defined by the following laboratory parameters:
- ALT (alanine aminotransferase) or AST (aspartate aminotransferase) greater than two times the upper limit of reference range
- Serum creatinine greater than 2.3 mg/dL
- Bilateral renal artery stenosis; renal artery stenosis in a solitary kidney; post-renal transplant
- NYHA (New York Heart Association) functional class CHF (chronic heart failure) III-IV
- Unstable angina, myocardial infarction or cardiac surgery within the preceding three months
- Stroke within the preceding six months
- PTCA (percutaneous transluminal coronary angioplasty) within the preceding three months
- History of angioedema
- Sustained ventricular tachycardia, atrial fibrillation, or other clinically relevant cardiac arrhythmias as determined by the clinical Investigator
- Hypertrophic obstructive cardiomyopathy, aortic stenosis, hemodynamically relevant stenosis of aortic or mitral valve
- Administration of digoxin or other digitalis-type drugs
- Patients with insulin-dependent and non-insulin-dependent diabetes mellitus
- History of drug or alcohol dependency
- Use of antihypertensive agents such as diuretics, ACE inhibitors, angiotensin II antagonists, α-blockers, β-blockers, calcium channel antagonists, direct vasodilators at any time during the trial
- Administration of other non-antihypertensive medications known to affect blood pressure (e.g., oral corticosteroids, MAO (monoamine oxidase) inhibitors, nitrates) at any time during the trial
- Chronic administration of high doses of NSAIDS and aspirin (e.g., ibuprofen for rheumatoid arthritis and osteoarthritis in total daily dose in excess of 1600 mg, aspirin in excess of 2 Gm per day)
- Chronic use of salt substitutes containing potassium chloride; potassium supplements; extreme dietary restrictions
- Clinically significant sodium depletion as defined by a serum sodium level less than 130 mEq/L
- Clinically significant hyperkalemia as defined by a serum potassium level greater than 6.0 mEq/L. Clinically significant hypokalemia as defined by a serum potassium level less than 3.0 mEq/L
- Patients receiving any investigational therapy within one month of signing the informed consent form. Note that patients who have participated in previous telmisartan studies may participate in this study provided there has been at least one month between discontinuing the previous study and signing the consent for the present study
- Known hypersensitivity to any component of telmisartan
- Any other clinical condition which, in the opinion of the principal Investigator, would not allow safe completion of the protocol and safe administration of trial medication
