All subjects should be judged normal and healthy during a pre-study medical evaluation (physical examination, laboratory evaluation, hepatitis B and hepatitis C tests, HIV test, 12-lead ECG, and urine drug screen including amphetamine, barbiturates, benzodiazepines, cannabinoid, cocaine, opiate screen, phencyclidine, and methadone) performed within 14 days of the initial dose of study medication. Exclusion Criteria: Institutionalized subjects will not be used. Social Habits: Use of any tobacco products within 1 year of the start of the study. Ingestion of any alcoholic, caffeine- or xanthine-containing food or beverage within the 48 hours prior to the initial dose of study medication. Ingestion of any vitamins or herbal products within the 7 days prior to the initial dose of the study medication. Any recent, significant change in dietary or exercise habits. A positive test for any drug included in the urine drug screen. History of drug and/or alcohol abuse. Medications: Use of any prescription or over-the-counter (OTC) medications within the 14 days prior to the initial dose of study medication. Use of any medication known to alter hepatic enzyme activity within 28 days prior to the initial dose of study medication. Diseases: History of any significant cardiovascular, hepatic, renal, pulmonary, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic disease. Acute illness at the time of either the pre-study medical evaluation or dosing. A positive HIV, hepatitis B, or hepatitis C test. Abnormal and clinically significant laboratory test results: Clinically significant deviation from the Guide to Clinically Relevant Abnormalities (See Part II ADMINISTRATIVE ASPECTS OF BIOEQUIVALENCE PROTOCOLS). Abnormal and clinically relevant ECG tracing. Donation or loss of a significant volume of blood or plasma (> 450 mL) within 28 days prior to the initial dose of study medication. Subjects who have received an investigational drug within 30 days prior to the initial dose of study medication. Allergy or hypersensitivity to zonisamide or any other sulfa drugs. History of difficulties in swallowing, or any gastrointestinal disease which could affect the drug absorption. Consumption of grapefruit or grapefruit containing products within 7 days of drug administration.
