  • Patent number: 8496944
    Abstract: The invention relates to an improved process for the production of powders of an inhalable medicament by crystallization from a supersaturated fluid containing said medicament, the method comprising passing along a tubular reactor (a) a segmented flow of that fluid comprised of discrete volumes; or (b) a fluid mixture being separated by discrete volumes of a separating fluid which is substantially immiscible with said fluid, characterized in that the crystallization is initiated by application of ultrasound.

  • Patent number: 7984713
    Abstract: The invention relates to a powder inhaler (1) with mouthpiece (2) for dispersing pharmaceutical medicament formulations, which comprises an auxiliary energy source in the form of a pressure medium system (3), having a device for supplying (6) a powder formulation (7), while on activation of the pressure medium system a gaseous pressure medium (8) released by the pressure medium system (3) forms an aerosol (9) with the powder formulation (7) such that the powder particles are present in the gaseous pressure medium (8) in dispersed form. This is achieved by means of a powder inhaler (1) comprising a multi-channel nozzle, the channels of which are inclined to one another at an angle such that the aerosol jets flowing through them meet one another downstream behind the nozzle (10).

  • Patent number: 7708011
    Abstract: A dry powder inhaler (1) is to be made available, with which a particle size and particle size distribution preferred for inhalation are to be achieved and by means of which as high a line particle fraction as possible is to be realized. This is achieved by means of a dry powder inhaler (1 ) that is characterized in that provided in the inhaler (1) is a nozzle (10) through which the aerosol (9) flows before leaving the inhaler (1).

  • Patent number: 7249599
    Abstract: A method for crystallizing a substance, especially an inhalable medicament, comprising the following steps: (a) dissolving said substance in a solvent, to produce a solution of said substance, (b) producing a segmented stream which consists of alternating segments of said solution of the substance and of a transport medium, (c) introducing said segmented stream into the first end of a retention stretch, which retention stretch has a first end and a second end, so that said segmented stream passes from said first end to said second end of said retention stretch, and exists from the second end of the retention stretch, (d) cooling the retention stretch, to thereby bring about crystallization of the substance in the segments of solution, in the segmented stream, as said segmented stream passes through the retention stretch, and (e) separating the crystals of material from the segmented stream as it exits from the second end of the retention stretch.
