In Vitro Product Quality Tests and Product Performance Tests for Topical and Transdermal Drug Products

Two categories of tests are performed: (i) product quality tests and (ii) product performance tests. Product quality tests are intended to assess attributes of the dosage form whereas product performance tests are designed to assess the performance of the dosage form that in many cases is related to the drug release from the dosage form. Quality and performance tests together assure identity, strength, quality, purity, and performance of the drug product. All quality and performance tests for topical dosage forms are described.
