摘要:
The present invention relates to a pharmaceutical formulation powder that contains 17α-hydroxyprogesterone caproate (17-OHPC) powder and the method of producing the formulation produces paritcles that are suitable as an inhalant. The formulations, methods and kits of powdered 17-OHPC as taught herein may be used to reduce cytokine interleukin-17 (IL-17 or IL-17A) levels in both broncheoalveolar lavage fluid (BALF) and blood/serum and involve the inhibition of p38 mitogen activating protein kinase (MAPK) activity. The 17-OHPC powder formulation may be used in a method to treat IL-17 cytokine and/or p38 MAPK mediated auto- immune and auto-inflammatory diseases. Such diseases may include glucocorticoid (GC) insensitive related diseases or conditions. In alternate embodiment, the formulation may include the combined use of budesonide (BUD) and/or fluticasone with 17-OPHC.

A method of preparing an inhalable insulin suitable for pulmonary delivery includes: dissolving an insulin raw material in an acidic solution to form a dissolved insulin solution; titrating the dissolved insulin solution with a buffer solution to form a suspension comprising micronized insulin particles; and stabilizing the micronized insulin particles.
摘要:
The present invention discloses a scalable and solvent-free method to produce cocrystals in a particulate form. A method of making cocrystals comprises the steps of: a) feeding a molten mixture of at least a first substance and a second substance which are able to form cocrystals to an atomizer; b) atomizing the molten mixture to droplets; c) solidifying the droplets to particles; d) collecting the said particles. The invention also provides the use of cocrystals made according to the method of the invention in the formulation of a pharmaceutical composition. The invention also provides cocrystals obtainable or obtained by the method of the present invention, in particular cocrystals in the form of particles. Also provided is a pharmaceutical composition comprising cocrystals made according to the method of the invention, in particular, a pharmaceutical composition comprising cocrystals in the form of particles made according to the method of the invention.

This invention provides an injectable formulation to be administered intramuscularly or subcutaneously that is used for the prevention or treatment of polycystic kidney disease, and that can maintain a therapeutically effective blood concentration of tolvaptan for a long period of time; and a process for producing the same. More specifically, this invention relates to an injectable depot formulation comprising (1) a particle containing optically active tolvaptan as an active ingredient and (2) a pharmaceutically acceptable carrier for injection, and a process for producing the same.
摘要:
Methods for preparing lyophilized pellets of antibodies that specifically bind to human IL-23 are described. The pellets have a substantially spherical shape and are prepared by freezing droplets of a liquid composition of a desired biological material on a flat, solid surface, in particular, a surface that does not have any cavities, followed by lyophilizing the frozen droplets. These methods are useful for preparing lyophilized pellets having a high concentration of anti-IL-23 antibody, and which have a faster reconstitution time than lyophilized powder cakes prepared in vials. Also provided are improved formulations for use in preparing lyophilized forms of antibodies that specifically bind to human IL-23.
摘要:
Es wird ein Verfahren zur Vergrößerung der Partikelgröße kristalliner Wirkstoff-Mikropartikel bereitgestellt, umfassend die Schritte, daß (a) eine erste Suspension aus kristallinen Wirkstoff-Mikropartikeln mit einem ersten d 50 -Wert von 0,5 - 5 μm, Lösungsmittel für den Wirkstoff und Antilösungsmittel für den Wirkstoff bereitgestellt wird, wobei die Löslichkeit des Wirkstoffs im Lösungsmittel-Antilösungsmittel-Gemisch der ersten Suspension 0,001 - 0,5 Gew.-% beträgt, (b) die erste Suspension durchmischt wird, (c) mindestens einmal der d 50 -Wert der in der ersten Suspension enthaltenen Wirkstoff-Mikropartikel bestimmt wird, wobei ein zweiter d 50 -Wert erhalten wird, (d) die erste Suspension weiter durchmischt wird, (e) die erste Suspension abfiltriert wird, wobei ein Filterkuchen entsteht, der mit Antilösungsmittel für den Wirkstoff gewaschen wird, wobei beim Abfiltrieren ein Differenzdruck von ≤ 500 mbar zwischen Oberseite und Unterseite des Filterkuchens vorliegt und der Filterkuchen nicht unter 80 Gew.-% Antilösungsmittel, bezogen auf die Gesamtmasse des Filterkuchens, entfeuchtet wird, der erhaltene Filterkuchen anschließend in Antilösungsmittel suspendiert wird, wobei eine zweite Suspension erhalten wird und der d 50 -Wert der Wirkstoff-Mikropartikel der zweiten Suspension bestimmt wird, wobei ein dritter d 50 -Wert erhalten wird, wobei abhängig vom zweiten d 50 -Wert die gesamte Durchmischungszeit der ersten Suspension zwischen 1 und 72 h so gewählt wird und/oder durch Zugabe von Lösungsmittel und/oder Antilösungsmittel die Löslichkeit des Wirkstoffs im Lösungsmittel-Antilösungsmittel-Gemisch der ersten Suspension zwischen 0,001 und 0,5 Gew.-% so geändert wird, daß der dritte d 50 -Wert mindestens 0,03 μιη größer als der erste d 50 -Wert ist, und (f) die Wirkstoff-Mikropartikel der zweiten Suspension anschließend getrocknet werden. Des weiteren werden kristalline Fluticasonpropionat-Partikel bereitgestellt, wobei die mittlere Partikelgröße d 50 = 1 - 1,5 μm beträgt, der Span ≤ 1,35 ist und der amorphe Anteil, bezogen auf das Gesamtgewicht der Partikel, ≤ 0,5 Gew.-% ist.
