Family History of Alcoholism Affects Response to Drug Used to Treat Heavy Drinking

20.09.2007
Naltrexone is one of four oral medications approved by the U.S. Food and Drug Administration (FDA) for the treatment of alcoholism.

A recent large multicenter research study of alcohol dependence supported by the National Institute of Alcoholism and Alcohol Abuse (NIAAA), the COMBINE Study, suggested that naltrexone produced a modest but significant benefit but another FDA-approved medication, acamprosate, was ineffective. Perhaps consistent with its modest effects in COMBINE, naltrexone is not widely prescribed in the treatment of alcoholism.

Yet, clinicians report that naltrexone may have significant benefits for individual patients. To make naltrexone a more useful medication, it would be important to begin to identify groups of patients who might be more or less likely to show a significant clinical benefit from naltrexone prescription and to understand the causes of differential naltrexone efficacy. A new study that will appear in the September 15th issue of Biological Psychiatry suggests that alcohol dependent individuals with a family history of alcohol dependence may be more likely than alcohol dependent individuals without a family history of alcohol dependence to reduce their drinking in the laboratory when prescribed naltrexone.

Krishnan-Sarin and colleagues at the NIAAA Center for the Translational Neuroscience of Alcoholism studied alcohol consumption in the laboratory by alcohol-dependent individuals who were not seeking treatment. The participants were studied in the laboratory after 6 days of treatment with 0 mg (placebo), 50 mg, or 100 mg of naltrexone. The authors discovered that naltrexone decreased drinking in those with a family history of alcoholism and this effect was greatest with the highest naltrexone dose. However, it increased drinking in those without a family history of alcoholism and this effect was greatest at the highest naltrexone dose.

John H. Krystal, M.D., one of the authors, notes that “When studied in large groups, naltrexone appears to have a rather small effect upon the ability to reduce drinking or remain abstinent from alcohol. However, there is growing evidence that there are subgroups of patients who show substantial benefit from naltrexone, even when naltrexone fails to work in the overall trial (see Gueorguieva R et al. Biol Psychiatry. 2007 Jun 1;61(11):1290-5).” According to Suchitra Krishnan-Sarin, Ph.D., the lead author, “The results suggest that family history of alcoholism may be an important predictor of clinical response to naltrexone and could potentially be used to guide clinical practice.” Dr. Krystal agrees, “These data suggest that family history might influence the optimal dosing of naltrexone and the nature of the clinical response.” Their hope is that these findings ultimately can contribute to a better treatment experience for some who are seeking to end their battle with alcohol.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
