Nanomilling is the process by which the particle size of an API is reduced in a liquid vehicle (typically aqueous) via grinding using polymeric or ceramic media. Nanomilling is a proven, commercially validated process for formulating poorly water-soluble APIs. The key is the tremendous increase in surface area which directly correlates to an ...
