  • Publication number: 20200024298
    Abstract: The invention relates to a novel crystallisation process for preparing fluticasone propionate as crystalline form 1 polymorph with controlled particle size and suitable for micronisation. Said process comprises the step of dissolving fluticasone propionate in acetone or in a mixture of acetone and water and then adding this solution to water or to a mixture of water 10 and acetone, thereby causing fluticasone propionate to crystallise out of the solution as crystalline form.

  • Patent number: 9757397
    Abstract: Provided according to some embodiments of the invention are methods of manufacturing a pharmaceutical composition. In some embodiments, such methods include homogenizing at a first excipient composition that includes a viscosity agent and at least one solvent to form a first premix composition; separately homogenizing at least one active pharmaceutical ingredient (API) and a second excipient composition to form a second premix composition; and combining the first premix composition and the second premix composition to form the composition. The pre-mixing of constituents may increase the stability of the API and provide uniformity of the dispersion of the constituents throughout the final topical composition.
