Crystallization inhibitors maintain super saturation of free drug during the absorption window upon oral administration. Formulators can achieve this by utilizing function excipients which provide solubilization enhancement and crystallization inhibition. We recently used the inhibitors to limit precipitation of drugs during the lipolysis of SEDDS and correlated with the Vivo performance. Additionally, these functional inhibitors effectively increased drug load and improved overall bioavailability by forming supersaturated-SEDDS. This podcast will cover the role of crystallization inhibitors in formulation and how to use in SEDDS formulation effetely.
