Summary

Primary objective: To demonstrate the no-inferiority in efficacy of treatment with Torsemide-PR in relation to Torsemide-IR in patients with mild and/or moderate hypertension.

Secondary objectives: To evaluate the safety and tolerability of Torsemide-PR.

Clinical Details

Official title: Multicentre, Multinational, Parallel, Randomised, Double Blind Clinical Trial, to Evaluate the Non-Inferiority of PR Torasemide Versus IR Torasemide in Patients With Mild or Moderate Arterial Hypertension.

Study design: Treatment, Randomized, Double-Blind, Active Control, Parallel Assignment, Safety/Efficacy Study

Primary outcome: Difference in mm Hg between the mean diastolic blood pressure (DBP) values the baseline period and the values at the end of the treatment period.

Secondary outcome:

Difference in mm Hg, systolic blood pressure (SBP) values in the baseline period and the values at the end of the treatment period.

Percentage of patients with controlled blood pressure (SBP < 140 and/or DBP < 90) at the end of the treatment period.

Urinary symptoms.

ABPM values measured in a subgroup of patients

Safety & tolerability.

Detailed description: Torsemide is a loop diuretic from the group of pyridine-sulfonylureas, which acts on the ascending large portion of the Henle loop where it inhibits the Na+/K+/2Cl- transport!system and blocks Cl- channels. Therefore, sodium and chlorine ions and water can not be reabsorbed in the tubule and the urine volume increases significantly. Torsemide is used for the treatment of oedema associated with congestive heart failure, kidney or liver disease and, either alone or combined with other anti-hypertensive drugs, for the treatment of arterial hypertension.

This trial compares the effect of a new formulation of Torasemide (Torasemide prolonged release)to the already available immediate release formulation of the same drug on the treatment of mild to moderate hypertensive patients.

Eligible patients will be randomised to either treatment with Torasemide prolonged release or with Torasemide immediate release and will be followed-up until completing 3 months of treatment. Blood pressure will be measured by an OMRON pressure gauge. Additionally, ABPM will be performed on a sub-group of the patients taking part in this trial.

2. Patients with prior anti-hypertensive treatment in monotherapy who do not respond to the treatment and, in the investigator's opinion, could benefit from diuretic treatment in monotherapy.

3. Patients with prior anti-hypertensive treatment in monotherapy who do not tolerate the current treatment and, in the investigator's opinion, could benefit from diuretic treatment in monotherapy.

Patients with prior treatment must be able to interrupt their present treatment for a period of up to 3 months.

8. Unstable angina pectoris.

9. Acute myocardial infarct in the last 6 months.

10. Liver failure defined by the following analytical parameters: - SGPT (ALT) or SGOT

(AST) over twice the upper normal limit.

12. Patients with insulin-dependent diabetes and patients with non-insulin dependent diabetes.

13. Cerebrovascular accident in the last 6 months.

14. Contraindications in the data obtained during the selection process in the physical examination, haematology, biochemistry, urine analysis and 12-lead ECG, in the investigator's opinion.

15. Simultaneous participation in another clinical trial or treatment with any investigational drug within the 30 days prior to signing the informed consent form.

16. Lactose intolerance.

17. Concomitant treatment with lithium.

18. Patients requiring chronic treatment (treatment > 7 days) with non-steroidal anti-inflammatory drugs, including aspirin.

19. Patients with concomitant treatment with aminoglycoside antibiotics, etacrynic acid.

20. Chronic administration of any medication affecting blood pressure.

21. Patients in treatment with group 1a, 1b or 2 anti-arrhythmic drugs.

22. History of drug or alcohol addiction within the 6 months prior to the start of the trial.

23. Any clinical circumstance or condition which, in the investigator's opinion, could affect the possibility of completing the protocol and the administration of Torasemide.

24. Obesity with a body mass index (BMI) of over 40 kg/m2.
