In preclinical studies three novel anticonvulsants have been studied. The administration of tiagabine did not decrease ethanol consumption in rodents (Schmitt et al., 2002; Rimondini et al., 2002). In a study with alcohol preferring mice topiramate reduced alcohol consumption in a two bottle choice prolonged access model of drinking (Gabriel and Cunningham, 2005). In a study done at our laboratory both topiramate and zonisamide were found to have similar effects on reducing the consumption of ethanol in Wistar rat (Knapp et al., 2004). More recently we found that zonisamide administration decreased alcohol consumption in a limited access model in the C57BL/B6 mouse. These results suggest that zonisamide might be useful as a medication for the treatment of alcohol dependence.
