April 22, 2024 updated by: Mylan Pharmaceuticals Inc
Steady-State Bioequivalence Study of Extended Phenytoin Sodium Capsules (100 mg; Mylan) and Dilantin® Kapseals® (100 mg; Pfizer) in Healthy Adult Volunteers
The objective of this study was to investigate the steady-state bioequivalence of Mylan's extended phenytoin sodium capsules, 100mg (3x100mg), to Pfizer's Dilantin® Kapseals®, 100mg (3x100mg), under both fasting and fed conditions.

- Weight: At least 60 kg (132 lbs) for men and 48 kg (106 lbs) for women and all subjects within 15% of their 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).
- 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 21 days of the initial dose of study medication.
Exclusion Criteria:
- Institutionalized subjects will not be used.
Social Habits:
- Use of any tobacco-containing 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 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 hormone replacement therapy within 3 months prior to study medication dosing.
- 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, or 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.
- History of porphyria.
- History of diabetes.
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 phenytoin or any other hydantoins.
