    • A method for producing particles, from a substance, having predetermined size and/or morphology characteristics. The method consists of mixing within a spray nozzle a solution stream containing the substance in dissolved or dispersed form with a supercritical fluid stream. Spraying the mixture through a nozzle into a particle collecting chamber and there separating the particles. The characteristic feature is an additional step, providing a make-up agent (modifier) to the fluid stream, possibly combined with recycling of the fluid and/or performing the method essentially simultaneously in several spray nozzles. Additional features are also a production system comprising functions for performing the method above and the introduction of the make-up agent, recycling of the fluid and performing several runs essentially simultaneously in the same production system. Also a pharmaceutical formulation in which particles produced according to the method has been used for its manufacture.

    • A method for producing particles of predetermined sized and/or morphology of a substance in a production arrangement comprising the steps of: i) mixing within a spray nozzle and under flow conditions a stream of a liquid solution in which the substance is dissolved with a stream of a fluid, and ii) passing the mixture in the form of a spray through a spray outlet of the nozzle into a particle collecting container, and iii) separating and collecting within the container the particles. The characteristic feature is that the solvent is a liquid and the fluid is an aqueous liquid in a subcritical state. Preferred nozzles have two coaxial internal transport conduits. One aspect is a production arrangement that can be used in the method. Its characteristic features are functions for a) recycling fluid used in the process, b) for including a make-up agent in the fluid stream, and/or increasing production by paralleling particle formation.
