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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
