Who can join

Age: 21 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Female/male veterans aged 21-70 years
• Regular heavy drinkers as defined by averaging 2 heavy drinking days per week over 90 days baseline pre-treatment timeline follow-back (TLFB), and current alcohol dependence diagnosis by the Diagnostic and Statistical Manual IV Text Revision (DSM-IV-TR) that recognize a need to reduce or stop drinking (Note: heavy drinking days will be defined as follows; for men greater than or equal to 5 drinks in a day and for women greater than or equal to 4 drinks in a day)
• Women of child-bearing potential (i.e., no hysterectomy, bilateral oophorectomy, or tubal ligation or <2 years postmenopausal), must be non-lactating, practicing a reliable method of birth control, and have a negative serum pregnancy test prior to initiation of treatment;
• Willingness to provide signed, informed consent to participate in the study

You may not qualify if…

• A current, clinically significant physical disease or abnormality (i.e., neurologic, renal, rheumatologic, gastrointestinal, hematologic, pulmonary, endocrine, cardiovascular, hepatic, or autoimmune disease that, in the context of the study would represent a risk to the subject, or significant laboratory abnormalities such as hepatic aminotransferase levels [i.e., aspartate aminotransferase (AST) and alanine aminotransferase (ALT)] greater than 300% of the upper limit of normal or direct bilirubin levels >150% of the upper limit of normal) on the basis of medical history, physical examination, or routine laboratory evaluation. Other specific exclusionary disorders include;
• History of renal calculi or renal failure; a significant indication of renal compromise will be defined by an elevation of serum creatinine above the investigators' laboratory's limit of normal, or a known history of renal failure or chronic renal disease, or any current or chronic disease that could reasonably be expected to result in renal failure
• History of hypersensitivity to zonisamide or any sulfonamide, Stevens-Johnson Syndrome, penicillin allergy, or history of any severe drug allergic reaction;
• History of systemic autoimmune disease such as lupus erythematosis, fibromyalgia, or rheumatoid arthritis;
• Current blood dyscrasia or a history of such, with the exception of a past history of iron deficiency anemia
• History of seizure disorder
• Use of any of a number of medications that might prominently influence drinking patterns or cause risk of harm or injury (e.g., topiramate, disulfiram, naltrexone, acetazolamide, stimulants such as amphetamine, or tramadol;
• Schizophrenia, bipolar disorder, posttraumatic stress disorder (PTSD), or substantial suicide or violence risk (i.e., can't be managed safely in the outpatient setting) on the basis of history or psychiatric examination; j) currently dependent on opioids or benzodiazepines or other sedatives
• Considered by the investigators to be clinically inappropriate for study participation or have participated in another pharmacotherapy study in the past thirty days
• Subjects with prominent signs of physical dependence, and/or medical comorbidities such that study physicians feel they should consider immediate detoxification, and referred for medical detoxification in a normal treatment setting
