    • 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.
    • 本公开提供了改进的利用胶体/超细超级基质复合颗粒用于活性药剂的分散和/或溶解的系统和方法。 通常,本公开内容通过在制剂中掺入湿法研磨的SDI作为分散剂来使用无表面活性剂的或接近表面活性剂的制剂。 因此,本公开内容通过在制剂中掺入湿磨超级崩解剂(SDI)作为分散剂来提供制备不含表面活性剂的或基本不含表面活性剂的制剂(例如纳米复合微粒子制剂)。 本公开的有利的SDI颗粒(例如,胶体/超细SDI颗粒)可用于分解制剂中活性剂(例如水不溶性药物)的聚集体(例如,纳米颗粒聚集体)(例如, 微粒子制剂),并且在水分散分散过程中增强活性剂纳米颗粒的回收率及其在体外和体内的溶解速率。
