Modafinil May Help Cocaine Users Prevent Relapse

treating cocaine addictions with modafinilThere is currently no Food and Drug Administration–approved treatment for cocaine addiction. One reason may be that in studies of treatments for cocaine use, participants may have a wide variety of exposure to cocaine. Some may be regularly using cocaine, while others may have gone some time without using the drug. A recent study by Margaret Haney and colleagues addressed some of these challenges by comparing the addiction treatment modafinil to placebo in different scenarios—such as when cocaine users have access to cheap cocaine versus expensive cocaine—and determining under which circumstances modafinil reduces the use of smoked cocaine.

In the study, presented at a scientific meeting in 2015, Haney and colleagues reported that among people who were not currently smoking cocaine, modafinil reduced cocaine use compared to placebo, but modafinil did not reduce cocaine use among people who had recently smoked cocaine. Modafinil also reduced cocaine use when the drug was expensive, but not when participants had access to cheap $5 cocaine. According to the researchers, these findings suggest that modafinil may be more useful at preventing relapse than at helping current users of cocaine achieve abstinence.

Editor’s Note: While they are not FDA-approved, two other treatments can reduce cocaine use, according to placebo-controlled studies: the antioxidant N-acetylcysteine (NAC) and the anticonvulsant topiramate.
