Heart Medication Shows Potential as Treatment for Alcohol Use Disorder
Spironolactone, a medication for heart problems and high blood pressure, may also be effective for treating alcohol use disorder (AUD), according to a new National Institutes of Health study. The study presents converging evidence from experiments in rodents, as well as electronic health data from humans, suggesting that spironolactone may play a role in reducing alcohol drinking. The research, published in Molecular Psychiatry, was led by scientists at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), the National Institute on Drug Abuse (NIDA), and Yale School of Medicine in New Haven, Connecticut.
“Seeing similarities across species and research designs gives us confidence that we are onto something potentially important scientifically and clinically,” said Lorenzo Leggio, M.D., Ph.D., chief of the Clinical Psychoneuroendocrinology and Neuropsychopharmacology Section, a joint laboratory of NIDA and NIAAA, and one of the study’s senior authors.
Less than 10 percent of people with AUD receive any treatment, despite the availability of behavioral treatments and three safe and effective medications approved by the U.S. Food and Drug Administration. Given the diverse biological processes that contribute to AUD and the variability in the presentations of the disorder across individuals, research to identify new medications is needed to provide a broader spectrum of treatment options that can be tailored to individual needs.
Previous preclinical research suggests that signaling through a specific corticosteroid receptor (mineralocorticoid receptors), which can be blocked by spironolactone, might play a role in alcohol consumption and craving. In the present study, researchers showed, through experiments performed in mice and rats, that spironolactone decreases alcohol consumption. Moreover, in a complementary analysis of health records of a large sample of people from the U.S. Department of Veterans Affairs health care system, the researchers found that individuals who had been prescribed spironolactone (for reasons such as heart problems or high blood pressure) were more likely to self-report reductions in alcohol consumption.
“These results are encouraging,” said NIAAA Director George F. Koob, Ph.D., a co-author of the study. “This study provides scientific support for clinical studies to understand how the medication may reduce alcohol consumption and assess the safety and potential efficacy of spironolactone in humans with AUD.”
