This article describes the data processing procedures and FDA statistical mathematics of an in-vitro permeation test (IVPT) study for evaluating a generic topical drug product against its reference product. IVPT-Stat v2.0, a tool composed of two Microsoft (MS) Excel files, is provided in the present paper to perform FDA statistic bioequivalence analysis with IVPT data (i.e., maximum flux [Jmax] and total cumulative amount permeated [denoted as AMT]) of the test and reference topical drug products. The algorithms and use of IVPT-Stat v2.0 are also elucidated with examples. As a MS Excel-based tool, IVPT-Stat v2.0 is user friendly and can be easily run by most industry practitioners and should make IVPT data analysis easy.
