What this trial studies

This study aims to evaluate the effects of spironolactone, a medication typically used for high blood pressure, on individuals with alcohol use disorder (AUD). Participants will undergo four separate 7-day stays at a clinic in Baltimore, where they will take spironolactone capsules twice daily for five days. The study will assess how spironolactone interacts with alcohol in the body, focusing on its pharmacokinetics and pharmacodynamics, as well as monitoring safety and tolerability. The goal is to determine if spironolactone can be an effective treatment for reducing alcohol consumption in people with AUD.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 21 and older who have been diagnosed with alcohol use disorder.

Not a fit: Patients who do not have alcohol use disorder or those who are not able to comply with the study's requirements may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a new treatment option for individuals struggling with alcohol use disorder.

How similar studies have performed: While spironolactone has not been tested for alcohol use disorder specifically, its effects on alcohol consumption in animal studies suggest potential for success in this novel approach.

6. Current use of any diuretic, angiotensin receptor blocker (ARB), angiotensin converting enzyme inhibitor (ACEI), potassium supplementation, potassium containing salt substitute, heparin and low molecular weight heparin (LMWH), trimethoprim, lithium, digoxin, cholestyramine
7. Current use of MR antagonists
8. Current use of FDA-approved pharmacotherapy for AUD, or seeking treatment for AUD

11. Physical and/or mental health conditions that are clinically unstable, as determined by the study clinicians, including (but not limited to) major depressive disorder or generalized anxiety disorder unstable during the past three months or other psychiatric conditions (e.g., schizophrenia, bipolar disorder) unstable during the past twelve months prior to screening.
12. Pregnancy, intention to become pregnant, or breastfeeding.
13. Any other reason or clinical condition that the Investigators judge would interfere with study participation and/or be unsafe for a participant.
