ABSTRACT
Wear-resistant polymers and ceramics-based media have been used to pulverize the bulk powder of poorly water-soluble drugs to nanoscale size in conventional milling; however, contamination of such media is still an issue in the context of drug formulation manufacturing. In the present study, we developed a novel method for pulverizing the particles of a poorly water-soluble drug, ketoprofen, to nanoscale size by mixing mannitol and polypropylene glycol as a safe pulverizing medium. The ketoprofen nanoparticles were prepared using a Hoover automatic muller, equipment that traditionally has been used for the mixing of paint and ink. This process represents a novel application of this machine for the on-demand preparation of nanoparticulate formulations for use in the clinical setting. The optimal composition of the drug formulation was determined by designing an experiment consisting of the central composite design and responsive surface method. We obtained a design space that yielded ketoprofen nanoparticles with targeted particle size, poly-dispersity index, and drug release properties. We validated the manufacturing conditions by preparing ketoprofen nanoparticles in four compositions. Thus, the present study provided useful information regarding not only simple and effective contamination-free milling but also the experimental conditions need to produce nanoparticles of a poorly water-soluble drug.
