A medication for heart problems and high blood pressure may also be effective for treating alcohol use disorder, according to a new study by researchers at the National Institutes of Health and their colleagues. The study presents converging evidence from experiments in mice and rats, as well as a cohort study in humans, suggesting that the medication, spironolactone, may play a role in reducing alcohol drinking. The research was led by scientists at the National Institute on Drug Abuse (NIDA) and the National Institute on Alcohol Abuse and Alcoholism (NIAAA), both parts of NIH, and Yale School of Medicine, New Haven, Connecticut. A report of the new findings is published in Molecular Psychiatry.
