Pharmacokinetic Profile and Pharmacodynamic Characteristics of a Furosemide High Dosage Formulation in Patients With Chronic Renal Failure Undergoing Peritoneal Dialysis

Pharmacokinetic Profile and Pharmacodynamic Characteristics of a Furosemide High Dosage Formulation (PRLasix® Special, Tablets 500 mg) in Patients With Chronic Renal Failure Undergoing Peritoneal Dialysis

Primary Objective:

• To determine the absolute bioavailability of furosemide 500 mg (Lasix® Special) oral formulation in patients with chronic renal failure undergoing peritoneal dialysis.

Secondary Objectives:

• To determine the pharmacokinetic profiles of furosemide 500 mg (Lasix® Special) oral formulation and 250 mg IV formulation
• To compare the pharmacodynamic characteristics of furosemide 500 mg (Lasix® Special) oral formulation and 250 mg IV formulation

• Screening: 7 to 10 days
• Treatment period: 14 days (Period 1: 7 days; Period 2: 7 days)
• End of study: 7 days after the last dosing,
• Total duration from screening per subject: 22 to 25 days.

Inclusion criteria :

• Male or female, 18 years old or older, with chronic renal failure undergoing peritoneal dialysis for at least 3 months.
• Women of childbearing age should have a negative pregnancy test before administration of the study drug

Exclusion criteria:

• Contra-indications to furosemide, including:

  • Hypersensitivity to furosemide or to sulphonamide-derived drugs or to any ingredient in the formulation or component of the container.
  • Glomerular filtration rate below 5 mL/min
  • Glomerular filtration rate above 20 mL/min
  • Severe liver disease
  • Patients with renal failure accompanied by hepatic coma and precoma
  • Renal failure due to poisoning with nephrotoxic or hepatotoxic substances
  • Severe hyponatremia, hypokalemia, hypovolemia, dehydration or hypotension
  • Nursing women

• Pregnancy

• Treatment with any diuretic, which cannot be discontinued with the required washout period before the first drug administration

• Existence of any surgical or medical condition, which, in the judgment of the clinical investigator, might interfere with absorption, distribution, metabolism or excretion of drugs.

• Psychiatric or cognitive disturbance or illness, or recreational drug/alcohol use that, in the opinion of the principal investigator, would affect patient safety and/or compliance.

• Treatment with the following inhibitors of secretion at the renal level: clarithromycin, erythromycin, itraconazole, cyclosporin, ketoconazole, quinidine, and verapamil, which cannot be discontinued during the course of the study.

Interfering substance:Subjects must abstain from alcohol and beverages containing stimulating xanthine derivates (e.g. coffee and tea) during the entire study period.
