Hello Preocupado,
There are a few different medications that may help. The anti-alcohol medicine called antabuse (disulfiram) also help block the cravings of cocaine addiction. Several anti-
seizure medicines can help reduce cravings as well, such as gabapentin.
There is a medication called Nocaine that helps block the effects of cocaine and reduce the high that is obtained; however, this medicine is currently only in trials and not available publically. I do not know when this will be available, if it passes the trials.
You may want to seek the advice of a psychiatrist that specializes in drug abuse for some recommendations about some of these medicines.
Best wishes.
