    Abstract: Disclosed are methods and devices for producing very fine particles which are then coated with protective polymers in another step of the process. The particles are produced using a method in which a liquid flow comprising a particle-free liquid 1 that contains the active substance in a dissolved form is combined with a second liquid flow comprising a liquid 2 in a high-energy zone or no sooner than two seconds before reaching the high-energy zone. Said two liquids can be mixed with each other while the active substance dissolved in liquid 1 is insoluble or more difficult to dissolve in liquid 2 than in liquid 1 and settles in the form of particles in the high-energy zone or within a maximum of 2 seconds before reaching the high-energy zone when the two liquids are mixed. The obtained particles are introduced into an aqueous outer phase which contains the coating materials in a dissolved form and are then subjected to a drying step such that said materials settle on the particles as a closed coating. The coated particles are protected from damaging influences and are provided with modified release kinetics compared to uncoated particles.

    Abstract: The invention relates to solid, particulate lipid-based excipients which are loaded with cyclosporine. Said excipients have improved biopharmaceutical properties for cyclosporines in vivo, are of a better quality (in terms of fineness, homogeneity of the particles, inclusion of the medicament) and are more physically stable in the particulate formulation (no aggregation or gel formation). The invention also relates to a therapeutic treatment with cyclosporine formulations which produce an average blood level concentration in the steady state range of 300 ng/ml to over 1000 ng/ml, preferably over 800 ng/ml, especially up to 900 ng/ml, preferably 400 ng/ml to 800 ng/ml in the absence of high initial blood level concentrations essentially over 1500 ng/ml, especially over 1200 ng/ml. This blood level concentration is preferably maintained for an extended period of at least 5 hours, preferably at least 7 hours.
