Abstract

See full text

The present disclosure provides improved systems and methods utilizing colloidal/ultrafine superdisintegrant-based composite particles for dispersion and/or dissolution of active pharmaceutical agents. In general, the present disclosure utilizes a surfactant-free or near surfactant-free formulation by incorporating a wet milled SDI as a dispersant in the formulation. As such, the present disclosure provides for the preparation of surfactant-free or substantially surfactant-free formulations (e.g., nano-composite micro-particle formulations) by incorporating a wet-milled superdisintegrant (SDI) as the dispersant in the formulations. The advantageous SDI particles (e.g., colloidal/ultrafine SDI particles) of the present disclosure can be used to break-up the aggregates (e.g., nanoparticle aggregates) of the active agents (e.g. poorly water-soluble drugs) in the formulations (e.g., micro-particle formulations) and enhance the recovery of the nanoparticles of active agents during aqueous re-dispersion and their dissolution rate in vitro and in vivo.
