The purpose of this study is to evaluate and compare the relative bioavailability of a test formulation of zonisamide capsules to an equivalent dose of a reference formulation, Zonegran® (zonisamide) capsules, after a single oral dose administered under fasting conditions.
The purpose of this study is to evaluate and compare the relative bioavailability of a test formulation of zonisamide capsules to an equivalent dose of a reference formulation, Zonegran® (zonisamide) capsules, after a single oral dose administered under fasting conditions.
Thirty-four healthy, non-smoking, non-obese male and female volunteers at least 18 years of age will be randomly assigned in a crossover fashion to receive each of two zonisamide dosing regimens in sequence with a 28 day washout period between dosing periods. On the morning of Day 1, after an overnight fast, subjects will receive either a single oral dose of the test formulation, zonisamide (1 x 100 mg capsule) or a single oral dose of the reference formulation, Zonegran® (1 x 100 mg capsule). After a 28 day washout period, on the morning of Day 29 after an overnight fast, subjects will receive the alternate regimen. Blood samples will be drawn from all participants before dosing and for 72 hours post dose at times sufficient to adequately define the pharmacokinetics of zonisamide. A further goal of this study is to evaluate the safety and tolerability of this regimen in healthy volunteers. Subjects will be monitored throughout the confinement portion of the study for adverse reactions to the study drug and/or procedures. Blood pressure and heart rate will be obtained prior to dosing and as scheduled following dose administration. All adverse events whether elicited by query, spontaneously reported or observed by clinic staff will be evaluated by the investigator and reported in the subject's case report form.

Maximum Plasma Concentration (Cmax)
The maximum or peak concentration that the drug reaches in the plasma.
Time frame: serial pharmacokinetic plasma concentrations were drawn prior to dose administration (0 hour) and at 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 8, 10, 12, 16, 24, 36, 48, 60 and 72 hours after drug administration.
Area Under the Concentration Versus Time Curve From Time 0 to Time t [AUC(0-t)]
The area under the plasma concentration versus time curve, from time 0 to the time of the last measurable concentration (t), as calculated by the linear trapezoidal rule.
Time frame: serial pharmacokinetic plasma concentrations were drawn prior to dose administration (0 hour) and at 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 8, 10, 12, 16, 24, 36, 48, 60 and 72 hours after drug administration.
