Brief summary
The objective of this study was to investigate the bioequivalence of Mylan's divalproex sodium 500 mg extended-release tablets to Abbott's Depakote ER® 500 mg tablets following a single, oral 500 mg (1 x 500 mg) dose administered under fed conditions.

Inclusion criteria
1. Age: 18 years and older. 2. Sex: Male. 3. Weight: At least 60 kg (132 lbs) and within 15% of Ideal Body Weight (IBW), as referenced by the Table of Desirable Weights of Adults Metropolitan Life Insurance Company, 1999 (See Part II ADMINISTRATIVE ASPECTS OF BIOEQUIVALENCE PROTOCOLS). 4. All subjects should be judged normal and healthy during a pre-study medical evaluation (physical examination, including vital signs, laboratory evaluation, 12-lead ECG, hepatitis B and hepatitis C tests, HIV test, and urine drug screen including amphetamine, barbiturates, benzodiazepine, cannabinoid, cocaine, opiates, phencyclidine, and methadone) performed within 14 days of the initial dose of study medication. 5. During the course of the study, from study screen until study exit, all males must use a spermicide-containing barrier method of contraception in addition to their current contraceptive device (if any). This requirement should be documented in the informed consent form.
Exclusion criteria
1. Institutionalized subjects will not be used. 2. Social Habits: 1. Use of any tobacco products within 1 year of the start of the study. 2. Ingestion of any alcoholic, caffeine- or xanthine-containing food or beverage within 48 hours prior to the initial dose of study medication. 3. Ingestion of any vitamins or herbal products within 7 days prior to the initial dose of the study medication. 4. Any recent, significant change in dietary or exercise habits. 5. A positive test for any drug included in the urine drug screen. 6. History of drug and/or alcohol abuse. 3. Medications: 1. Use of any prescription or over-the-counter (OTC) medications within 14 days prior to the initial dose of study medication. 2. Use of any medication known to alter hepatic enzyme activity within 28 days prior to the initial dose of study medication. 4. Diseases: 1. History of any significant cardiovascular, hepatic, renal, pulmonary, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic disease. 2. Acute illness at the time of either the pre-study medical evaluation or dosing. 3. A positive HIV, hepatitis B, or hepatitis C test. 5. Abnormal and clinically significant laboratory test results: 1. Clinically significant deviation from the Guide to Clinically Relevant Abnormalities (See Part II ADMINISTRATIVE ASPECTS OF BIOEQUIVALENCE PROTOCOLS). 2. Abnormal and clinically relevant ECG tracing. 6. Donation or loss of a significant volume of blood or plasma (\> 450 mL) within 28 days prior to the initial dose of study medication. 7. Subjects who have received an investigational drug within 30 days prior to the initial dose of study medication. 8. Allergy or hypersensitivity to valproic acid or any other related products. 9. History of difficulties in swallowing, or any gastrointestinal disease which could affect the drug absorption. 10.
