Alcohol-Drug Interactions: Perspectives forward Research and Prevention

An Interview with Markku Linnoila, MD PhD

put drugs intos can affect driving performance. This is veritable of prescription and over-the-counter medications as well as of illicit unsalable articles Because alcohol and other physics may modify each other's weights in the body, the adverse consequences of other drugs on driving may be increased when they are combined with alcohol (see sidebar).

Knowledge in this area is limited. To summarize what is known, JOHN DORIA, an associate editor of Alcohol Health & Research World, interviewed MARKKU LINNOILA, MD PHD chief of the National Institute onward Alcohol Abuse and Alcoholism Laboratory of Clinical Studies, asking him to identify what is generally known. Dr. Linnoila has published extensively upon the effects of drugs and alcohol onward driving. He pointed out that although the adverse validitys on driving due to drug-alcohol interactions may involve put drugs intos of abuse--such as marijuana--they also may involve prescription or over-the-counter medications taken for of the like kind common conditions as allergies, depression, and insomnia.

Q to what degree large a role do alcohol-drug interactions play in causing traffic crashes? A. It's difficult to say, because the data are not extremely good. Some people strongly believe there is a problem; others wait to minimize the issue. As is usually the case, I think the verity lies somewhere in between.

The risk would appear to be to be high. For example, a certain number of data suggest that about one-half of psychiatric outpatients may drink and drive while taking psychoactive medication. an epidemiological studies show that 11 to 25 percent of arrested drinking drivers have been using put drugs intos but these data are about 20 years of advanced age The National Transportation Safety Board has amassed epidemiological data that show that 33 percent of give in exchange driver fatalities in the eight States that they sampled involved alcohol, marijuana, cocaine, or other drugs

one additional data come from studies measuring unsalable articles in motor vehicle operators and crash victims in crisis rooms. One such study deportment ed in Ontario found significant involvement of benzodiazepines [see sidebar] and more [i]or[/i] less antidepressants, particularly amitriptyline. Data from Norway give an inkling of that the use of benzodiazepines and alcohol together by way of persons involved in traffic accidents is more public than among the general population. in such a manner there is some evidence, still it is somewhat spotty.

Q Can any conclusions be drawn from laboratory studies examining the forces of these alcohol-drug combinations upon the psychomotor and perceptual skills involved in driving? A. Here again the available data are not adequate. most numerous pharmaceutical companies today specifically exhibition for alcohol interactions when developing put drugs intos to be used by large numbers of outpatients. These data are prepared primarily for review by dint of the Food and Drug Administration and are not readily available.

Published laboratory studies are scattered [i]or[/i] part of to the other the literature, and many of them are difficult to interpret because of inadequate experimental design, poor control selection, or limited validity of the ordeals Researchers at the University of Linburg at Maastricht in the Netherlands are spearheading a worldwide effort to rank-order mix with drugss according to the severity of their interactions with alcohol. It will require rather a large amount of work to extract on a level currently available information for this purpose

Q What stamps of drugs are most likely to be involved in combination with alcohol in traffic accidents? A. In general, the unsalable articles posing the most significant driving risk would appear to be to be the antianxiety agents (particularly the benzodiazepines), antipsychotic physics antidepressants, some of the stronger analgesics, and a certain cardiovascular drugs.

Also, there waits to be a lot of polysubstance abuse among the younger generation. The interactions of alcohol with marijuana, cocaine, and PCP are important from a public safety point of view. In particular, alcohol and marijuana have additive deleterious events on performance when used together, if it be not that this has not been extensively explored in the laboratory.

Q for what cause [i]or[/i] reason not? A. Ethically, one should not use drug-naive make liables for these kinds of studies. however getting subjects who are generally using these drugs in combination to participate in studies is difficult, and if potential enthralls are abstinent, it is ethically questionable to reintroduce them to addictive substances, perhaps putting them at risk of becoming addicted again. to this time at the same time, the information would be surpassingly important from a public safety point of view. It's not an easy topic to approach.

Q Is there any way to predict drug-alcohol interactions in the absence of experimental data? A. Certain interactions can be predicted based upon known mechanisms of action and onward animal studies. However, it's difficult to predict interactions for like purposes as operating a motor vehicle where somewhat acute interactions could have a major impact. Also, appropriate animal standards for that kind of work are hard to tend hitherward by. One could measure an animal's sleeping time, if it were not that this may not be fine-grained enough to predict more wily forms of impairment.
