This was achieved by applying quality by design (QbD) approach and its built-in quality control aspects to adhere to the general principles of sustainability including subsistence, efficiency, and consistency during the product life cycle. Upadacitinib is an inhibitor of the Janus kinase class of enzymes. In this study, the characterization of the reference product, physicochemical parameters of the drug molecule, and the quality target product profile was considered along with critical attributes of quality to initiate drug development. Critical attributes related to material properties, process parameters, and the formulation variables were identified, and their preliminary level of risk was assessed. The factorial design of an experiment with three center points was achieved using Design Expert v12 to investigate the customary monolithic extended-release tablets of matrix formulation. In order to evaluate tablet performance, critical quality attributes (CQAs) were determined by dissolution tests. Finally, factors that can influence the formulation, including its compositions, manufacturing procedures, and analytical evaluation, were examined. The goal was to identify formulations that exhibit a similar release pattern through the entire 12-h dissolution testing period.</p><h3>Materials and Methods</h3><p>Various release rates of biosynthesized polymer-based upadacitinib extended-release formulations were compared to the reference product, Innovator (Rinvoq), using in vitro dissolution test.

As the transdermal route for drug administration becomes a safer and more appealing alternative to hypodermic needles, the search for new CPEs and their development becomes more important.
