This article describes the data processing procedures used by the authors from 

 permeation test (IVPT) studies. The article also discusses FDA statistical mathematics of evaluating a generic topical drug product, specifically acyclovir cream, against its reference product. The authors demonstrate the use of IVPT-Stat, a statistical tool based on Microsoft (MS) Excel, which has been developed to perform FDA statistic bioequivalence (BE) analysis on data that contains cutaneous pharmacokinetic parameters (maximum flux, Jmax, and total cumulative amount permeated, denoted as AMT) of the test (T) and reference (R) topical drugs. The authors use examples to illustrate the algorithms and functionalities of the IVPT-Stat tool.
