Novel High-Drug-Loaded Amorphous Dispersion Tablets of Posaconazole; in vivo and in vitro Assessment

Amorphous solid dispersions (ASDs) can increase the bioavailability of drugs with poor aqueous solubility. However, concentration-sustaining dispersion polymers (CSPs) incorporated in ASDs can result in low drug loading and, therefore, a large dosage-form size or multiple units to meet dose requirements, potentially decreasing patient compliance. To address this challenge, a high-loaded dosage-form (HLDF) architecture for ASDs was developed, in which a drug is first spray-dried with a high glass transition temperature (Tg) dispersion polymer to facilitate high drug loading while maintaining physical stability. This study demonstrates in vivo performance of the HLDF architecture using posaconazole as a model drug.  To learn more, download our publication.
