Fludrocortisone for adults with aneurysmal subarachnoid hemorrhage
Official title: A Prospective, Blinded, Randomised Clinical Trial of Fludrocortisone Compared With Placebo in Critically Ill Patients Presenting With Aneurysmal Subarachnoid Haemorrhage
Run by The George Institute · NCT06409364 · Data updated 2026-11-12
This trial tests whether giving early enteral fludrocortisone to adults hospitalized with aneurysmal subarachnoid hemorrhage reduces death and long-term disability at six months.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with confirmed aneurysmal subarachnoid hemorrhage whose aneurysm has been secured, admitted to a participating ICU within 96 hours and able to receive enteral medication are ideal candidates.
✕Probably not a fit
Patients unable to receive enteral drugs, already on steroid/mineralocorticoid therapy, with severe cardiac/hepatic/renal failure, significant sodium abnormalities, pregnant, or with imminent death are unlikely to benefit or be eligible.

What this trial studies
This is a multicentre, prospective, randomized, blinded, placebo-controlled Phase 2 trial comparing enteral fludrocortisone with placebo in adults with aneurysmal subarachnoid hemorrhage whose aneurysm has been secured. Participants are enrolled within 96 hours of hospital admission and receive the study drug while treated in a critical care environment, with outcomes including death and dependency at six months. Key exclusions include inability to receive enteral medication, pre-existing glucocorticoid or mineralocorticoid therapy, significant cardiac/hepatic/renal failure, abnormal sodium, pregnancy, or imminent death. The trial is being run at three tertiary hospitals in New South Wales, Australia.
Why it matters
Potential benefit: If successful, it could reduce deaths and long-term disability after aSAH, improving patients' chances of returning to work and better quality of life.
How similar studies have gone: Use of fludrocortisone in aSAH is relatively novel with limited randomized data, though small studies and physiologic rationale support its potential to address salt-wasting and hemodynamic instability.
