Selection of excipients: Match excipient functionalities with drug properties. For example, if OXISTAT exhibits poor aqueous solubility, solubilizers or surfactants should be prioritized.
-
Formulation trials: Conduct iterative experiments to address stability, release profile, and manufacturability. Use Design of Experiments (DoE) to optimize excipient ratios.
-
Compatibility testing: Verify excipient-drug stability over shelf life, avoiding reactions such as degradation or polymorphic changes.
-
Scale-up considerations: Ensure excipients’ sourcing, cost, and regulatory status align with commercial production.
