Scientists are now for the solution of drug abuse by the case study about a drug, the drug could be the most effective drug treatment. This specific drug is also known for phobias. The U.S. Department of Energy's Brookhaven National Laboratory is further evidence that the drug known as D-cycloserine could play a role in the desire extinguishes the behavior of drugs or, more specifically to the dependence of psychotropic substances. Their study shows that mice with D-cycloserine were less likely to be a lot of time in an environment where it previously expected, the cocaine of mice treated with placebo. A student at the Stony Brook University as part of the Brookhaven Laboratory, Carlos Bermeo, as the link between drugs and the places where they may be used to trigger the desire and / or return of a man, a drug that helps the reduction or cessation of these reactions can be a powerful tool for the treatment of drug addiction. D-cycloserine was originally as an antibiotic. But this drug has also shown concern Climatisée deleted in preclinical (animal) studies and has been successfully tested in human clinical trials for the treatment of anxiety or fear of altitude. This finding led researchers to wonder whether D-cycloserine could remove the drugs, behavior, too. In 2006, a group of researchers are not commensurate with the Brookhaven Lab tested this hypothesis in rats. They found that D-cycloserine to facilitate the extinction of the "City of cocaine packed word" - in which the tendency for animals to spend more time in a room where it was cocaine from a room, where they do not have access to medicines that. This study is based on the work done so far and adds information on the dose-effect of drugs, the characteristics of sustainable treatment of musculo-skeletal system and the effects of this relationship. In the study, the group of C57BL / c mice. The animals were first trained to cocaine, in an environment. Once packed, a place like (the animals more easily in a time bound of cocaine in a neutral environment), the mice were developed with D-cycloserine or saline and were able to spend forty minutes, or cocaine - related drug is no longer available, or neutral environment. After one of its researchers, this paradigm would be analogous to a clinical approach, in which the new function in their natural context, the use of drugs, but this time without drugs. He added that the fall in search of drugs in the same environment, the behavior of extinction is an indicator for the future with great success in the treatment and reduces the likelihood of recidivism. However, these researchers argue that it is important to remember that these are very preliminary results of a study of small animals, and more research is needed before the drug in humans. However, it is inspiring to know that this promise in May medications to treat cocaine addiction, that of a toll for society and for which no medical treatment. These studies are another step in the treatment of phobias, and drug use.
