Inappropriate secretion of antidiuretic hormone treated with frusemide
British Medical Journal (Clinical Research Ed.)
|July 10, 1982
Summary
Frusemide effectively treats chronic inappropriate secretion of antidiuretic hormone (SIADH) when water restriction is not tolerated. Most patients responded well to daily frusemide doses, with electrolyte management crucial for success.
Area of Science:
- Nephrology
- Endocrinology
Background:
- Chronic inappropriate secretion of antidiuretic hormone (SIADH) presents challenges in management.
- Water restriction is a primary treatment but often poorly tolerated by patients.
Purpose of the Study:
- To evaluate the efficacy of frusemide as an alternative treatment for SIADH.
- To assess the optimal dosage and supportive measures for frusemide therapy in SIADH.
Main Methods:
- A study involving nine patients with chronic SIADH.
- Treatment with daily doses of frusemide (40 mg or 80 mg).
- Monitoring of diuresis, electrolyte balance, and creatinine clearance; sodium chloride supplementation and potassium management were employed.
Main Results:
- Seven out of nine patients showed successful treatment with frusemide (40 mg daily).
- One patient required 80 mg frusemide, while another with low creatinine clearance had limited response.
- Electrolyte imbalances, particularly hypokalemia, occurred in five patients but were manageable.
Conclusions:
- Frusemide is a viable and effective alternative for managing SIADH in patients unable to adhere to water restriction.
- Careful monitoring and management of electrolytes, including sodium and potassium, are essential during frusemide treatment for SIADH.
