This medication is indicated for the treatment of the following diseases:

  • arterial hypertension (high blood pressure)
  • edema (excess fluid in the tissue under the skin) due to heart, kidney, and liver insufficiency; premenstrual and idiopathic edemas (of unknown cause)
  • renal diabetes insipidus (a disorder in which a defect in the small renal tubules causes a person to eliminate a large amount of urine) when treatment with antidiuretic hormone is not indicated
