Nanosizing: a formulation approach for poorly-water-soluble compounds

Poorly-water-soluble compounds are difficult to develop as drug products using conventional formulation techniques and are frequently abandoned early in discovery. The use of media milling technology to formulate poorly-water-soluble drugs as nanocrystalline particles offers the opportunity to address many of the deficiencies associated with this class of molecules. NanoCrystal ® Technology is an attrition process wherein large micron size drug crystals are media milled in a water-based stabilizer solution. The process generates physically stable dispersions consisting of nanometer-sized drug crystals. Nanocrystalline particles are a suitable delivery system for all commonly used routes of administration, i.e. oral, injectable (IV, SC, and IM) and topical applications. In addition, aqueous dispersions of nanoparticles can be post-processed into tablets, capsules, fast-melts and lyophilized for sterile product applications. The technology has been successfully incorporated into all phases of the drug development cycle from identification of new chemical entities to refurbishing marketed products for improving their performance and value.
