Fabrication of hydrophobic drug nanoparticles using a microfluidic spray dryer

Title Early development drug formulation on a chip: Fabrication of nanoparticles using a microfluidic spray dryer

Early development drug formulation on a chip: fabrication of nanoparticles using a microfluidic spray dryer.

Early development drug formulation is exacerbated by increasingly poor bioavailability of potential candidates. Prevention of attrition due to formulation problems necessitates physicochemical analysis and formulation studies at a very early stage during development, where the availability of a new substance is limited to small quantities, thus impeding extensive experiments. Miniaturization of...

Steroid Nanocrystals Prepared Using the Nano Spray Dryer B-90

The Nano Spray Dryer B-90 offers a new, simple, and alternative approach for the production of drug nanocrystals. In this study, the preparation of steroid nanocrystals using the Nano Spray Dryer B-90 was demonstrated. The particle size was controlled by selecting the mesh aperture size. Submicrometer steroid particles in powder form were successfully obtained. These nanoparticles were confirme...

NANOPARTICLES. Production of amorphous nanoparticles by supersonic spray-drying with a microfluidic nebulator.

Amorphous nanoparticles (a-NPs) have physicochemical properties distinctly different from those of the corresponding bulk crystals; for example, their solubility is much higher. However, many materials have a high propensity to crystallize and are difficult to formulate in an amorphous structure without stabilizers. We fabricated a microfluidic nebulator that can produce amorphous NPs from a wi...

Stabilization of the Amorphous Structure of Spray-Dried Drug Nanoparticles.

The bioavailability of hydrophobic drugs strongly increases if they are formulated as amorphous materials because the solubility of the amorphous phase is much higher than that of the crystal. Moreover, the stability of these particles against crystallization during storage increases with decreasing particle size. Hence, it is advantageous to formulate poorly water soluble drugs as amorphous na...
