Following an overnight fast of at least 10 hours, all subjects were served a high-fat high calorie breakfast. Thirty minutes after the start of the meal, a single oral dose of 10 mL of oxcarbazepine 300 mg/5 mL oral suspension was administered using a 10 mL graduated syringe, during each period of the study under the supervision of trained study personnel, along with 240 mL of drinking water at ambient temperature.
