Brivaracetam Bioequivalence Assessment

This study assess the relative bioavailability performance of a test brivaracetam coated tablets compared with the EMA reference product, Briviact® 100 mg, in healthy adult volunteers of both sexes under fasting conditions. The pharmacokinetic profiles will be compared to assess whether the test product demonstrates equivalent rate and extent of absorption to the reference formulation.
