Measure
Group A: Crossover Between Low Dose Keppra and Placebo
Group A: Twenty moderate to heavy social alcohol users will receive 250 mg of levetiracetam BID (500 mg/day) or placebo x 7 days and will be titrated to a maximum dose of 500 mg of levetiracetam BID (1,000 mg/day) or will receive a double dose of placebo x 7 days. Participants on active drug for the first 14 days then crossed over to placebo after a 10-14 day washout period. Similarly, participants on placebo for the first 14 days then crossed over to active drug after a 10-14 day washout period.
Group B: Crossover Between High Dose Keppra and Placebo
Group B: Twenty moderate to heavy social alcohol users will receive 500 mg levetiracetam BID (1000 mg/day) or placebo x 7 days and will be titrated to a maximum dose of 1000 mg levetiracetam BID (2,000 mg per day) x 7 days or will receive a double dose of placebo x 7 days. Participants on active drug for the first 14 days then crossed over to placebo after a 10-14 day washout period. Similarly, participants on placebo for the first 14 days then crossed over to active drug after a 10-14 day washout period.
