Design of Experiments (DoE) Application in Two Cases of Study in Pharmaceutical Industries

Abstract

This study illustrates the practical application of Design of Experiments (DoE) in two real-life scenarios within the pharmaceutical industry. The first case involved optimizing a chromatographic method for the determination of multiple analytes and their degradation products. The primary variable of interest was gradient time, and the most favorable outcomes were achieved at a pH value of 2. In the second case, we conducted a shelf-life study for a veterinary product, revealing that the vial filling variable exerted a statistically significant impact (p-value < 0.05). The incorporation of DoE in both cases played an important role in ensuring the attainment of dependable and statistically validated results.
