Probenecid for Alcohol Use Disorder (PROB Trial)
Phase 1
Waitlist Available
Led By Carolina L Haass-Koffler, PHARMD
Research Sponsored by Brown University
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Be older than 18 years old
Timeline
Screening 3 weeks
Treatment Varies
Follow Up change from day 3 to day 10 of the trial
Summary
This trial tests an oral dose of 2g probenecid in people. Probenecid may change how the body handles alcohol. The study aims to see if this medication affects alcohol's impact on participants.
Who is the study for?
This trial is for adults aged 21-70 who drink more than the moderate amount weekly and are in good health. They must not be pregnant, breastfeeding, have kidney issues, or take certain medications like aspirin or methotrexate. Participants should not have other substance disorders (except nicotine) and no recent history of suicide attempts.
What is being tested?
The study tests Probenecid's effects on alcohol use disorder by comparing it with a placebo. Each participant will receive both treatments at different times in a controlled environment to see which one works better.
What are the potential side effects?
While specific side effects aren't listed here, probenecid may commonly cause allergic reactions in those sensitive to sulfa drugs, and interactions with various medications could occur.

Other Research
Common treatments for alcoholism include medications like disulfiram, naltrexone, and acamprosate. Disulfiram works by inhibiting the enzyme acetaldehyde dehydrogenase, causing unpleasant effects when alcohol is consumed, thus deterring drinking.
Naltrexone is an opioid receptor antagonist that reduces the rewarding effects of alcohol, helping to decrease cravings and relapse rates. Acamprosate modulates glutamatergic neurotransmission, stabilizing the chemical balance in the brain disrupted by chronic alcohol use.
These mechanisms are crucial for alcoholism patients as they address different aspects of addiction, from reducing the desire to drink to minimizing withdrawal symptoms, thereby supporting long-term recovery. Probenecid, while primarily used to inhibit renal excretion of uric acid, is being studied for its potential effects on other substances, which could offer new avenues for treating alcoholism by altering substance metabolism or excretion.
Chronic ethanol administration decreases 5-HT and increases 5-HIAA concentration in rat brain.
