How to Determine the Best Suppression Drug

Analyzing an individual’s genetic makeup can aid in the determination of which alcohol suppression drug will work the best. Since a key characteristic of alcoholism is the overwhelming urge to drink, prescription of the appropriate medication is vital to kicking the habit.

Two drugs can suppress the desire for alcohol: naltrexone works via the reward system in the brain and acamprosate via the stress system. However, they do not work for everybody. Dutch researcher Wendy Ooteman investigated if patient characteristics could predict which drug works best for which patient?

Temptation
One hundred and fifty-six alcoholics were willing to participate in Ootemans’ study. The participants’ desire to drink was aroused by, for example, placing a glass of their favourite drink on the table. Meanwhile they were posed questions about their urge for a drink and their physical reactions were measured, such as heart rate and sweat production. Genetic characteristics were also determined. After a month of treatment with naltrexone, acamprosate or a placebo the effect of clinical, physiological or genetic differences on the success of the treatment was examined.

Genetic indications
Clinical patient characteristics were found to be a poor predictor of whether someone would respond best to acamprosate or naltrexone. Biological and genetic characteristics could, however, predict this. People who started to sweat profusely during the experiment, responded better to acamprosate, whereas people who sweated less profusely responded better to naltrexone. Further genes which code for certain receptors in the brain predicted which drug would be successful for a patient. In particular, the genes that code for the mu-opioid receptor, the dopamine D2 receptor and a gaba receptor were found to be good predictors. This might be because these genes are closely associated with the causes of addiction.
