This study, as part of the curriculum of bioequivalence tests of domestic production, evaluates the bioequivalence of a 1000 mg Metformin tablet manufactured by Reihaneh Pharmaceutical Company with its reference sample
Design
Bioequivalency study of Metformin 1000 mg tablet (Reihaneh Pharmaceutical Company) and reference product of Glucophage are evaluated in 24 healthy volunteers. This study was cross-over, random, and double-blind.
Settings and conduct
This study is carried out in the central laboratory of the Hamadan School of Pharmacy. The 24 volunteers are randomly divided into two groups and are divided into two stages of the study. This study is double-blind and the recipient and analyzer will not be in the process of consuming the product. Blood samples will be collected from each volunteer at specified times for 24 hours.

Randomization (investigator's opinion)
Randomized
Randomization description
Each volunteer is identified by the number 1 to 24. The number assigned to each volunteer is based on the priority of being on the list when screening. Due to the cross-sectional study, 24 participants were assigned to test and reference products (groups A and B), respectively, using the Excel program rand command. Then, in the second stage, groups A and B will receive cross-reference and test drugs crosswise.
Blinding (investigator's opinion)
Double blinded
Blinding description
In this study, 24 volunteers were randomly divided into two groups of 12 test (A) and reference (B) drug recipients by Excel software. In this project, the volunteers, person responsible for blood sampling and analyzer are kept blind. To blind these people, all the information collected is coded to the researcher, and after the analysis is completed, codes will be opened.
