Protocol summary

Study aim
The study aims to compare the bioequivalence of carbamazepine tablets under fasting conditions.
Design
This randomized, single-dose, two-way, crossover study is conducted to compare the pharmacokinetics of carbamazepine and Tegretol® tablets in 24 healthy adult volunteers. Volunteers will be sorted and receive a number from 1 to 24. In the first phase of the study, 12 volunteers will receive carbamazepine manufactured by Ronak and the remaining 12 volunteers will receive Tegretol® produced by Novartis company. The administered drugs will be replaced to another group in the second phase of the study.
Settings and conduct
The dose administration and subsequent sample collection will be performed in Motahhari hospital (Gonbade Kavous, Iran).
Participants/Inclusion and exclusion criteria
Inclusion criteria: aged 18-55 years; subject available for the entire study period; willingness to adhere to protocol requirements as evidenced by written informed consent; good health at screening. Exclusion criteria: History of use of any drug; hypersensitivity or intolerance; significant history or current evidence of chronic disease; receipt of any drug as part of a research study within 30 days prior to the present study.
Intervention groups
First intervention group: A single 200 mg oral dose of carbamazepine (1 tablet) manufactured by Ronak company to 12 subjects. Second intervention group: A single 200 mg oral dose of Tegretol® (1 tablet) manufactured by Novartis company to 12 subjects. Since in this study, the volunteers will receive both test and reference drugs, each volunteer will act as his own control.
Main outcome variables
Drug plasma concentration; Area under the plasma concentration-time curve

History of a medical disorders occurring within the last year that required hospitalization or medication. Use of pharmacologic agents known to significantly induce or inhibit drug-metabolizing enzymes within 30 days prior to dosing. Receipt of any drug as part of a research study within 30 days prior to the present study. Donation or significant loss of whole blood (480 ml or more) within 30 days prior to the present study.
