The patent, which is titled ‘Method for Making Homogeneous Spray-Dried Solid Amorphous Drug Dispersions Using Pressure Nozzles,’ was assigned No 7,780,988 by the US Patent and Trademark Office.
The patent protecting the spray-dried dispersion (SDD) technology, covers a spray-drying process which can be used to make solid amorphous dispersions with larger particle sizes and minimal sized particles (fines).
The pressure nozzle spray-drying results in the formation of dense particles used for making solid dosage forms as tablets.
The patent addresses a problem encountered using conventional spray-drying processes which often produce small particles, including numerous very small particles, ‘fines’.
Bend Research president and CEO Rod Ray said that this patent is an important addition to the company’s spray-drying patent portfolio. Having patents that protect intellectual property offers them another key benefit by adding value to the formulations our scientists and engineers produce.
