Topiramate (Marketed as Topamax by Johnson & Johnson) prescribed for treatment of epilepsy, appears to reduce the craving for alcohol. Scientists believe brain chemical dopamine, provides the pleasure from alcohol and Topiramate works by suppressing away the excess dopamine, released by drinking alcohol. Research study in University of Texas Health Science Center at San Antonia, revealed those taking Topiramate, had a decrease in heavy drink or become abstinent from drinking (Six times more likely to remain abstinent for a month). Side effects common taking Topiramate includes, dizziness, weight loss, and memory problems. Compared to Naltexone and Acaomprosate achieved better results, however appeared to have more severe side effects. However, Topamax has not been tested thoroughly on alcoholics and physicians don’t know how long the medication should be taken. The National Insstitute of Alcohol Abuse and Alcoholism does not recommend Topamax, according to their 2005 clinical guide for treatig patients with drinking problems. In 2006 Dr. Bankole Johnson, chairman of the department of psychiatric medicine at the University of Virginia, recruiting patients for clinical trial of Topamax to treat alcoholism. Dr. Johnson predicts in a few years, the medication will be made available for treating alcoholics.
Patients undergoing chemotherapy, taking Zofran (Ondansetron), treats the side effects including nausea and vomiting. Researchers (University of Texas, Health Science Center in San Antonio) determined that a medium dose of Zofran, causes in most cases, alcoholics to abstain from drinking.
