Abstract: The present invention relates to a process for manufacturing porous silica particles comprising at least one bioactive compound, whereby the particles are adapted for lung, nasal, sublingual and/or pharyngeal delivery of said at least one bioactive compound and have an MMAD between 0.5 and 15 ?m with a GSD less than 2.5. The invention also relates to a pharmaceutical composition comprising said silica particles and a use of the silica particles in the diagnoses, prevention and/or treatment of local and/or systemic disorders, such as disorders of the lung, nose, sublingual and/or pharynx.

Abstract: According to the invention, there is provided a pharmaceutical composition suitable for administration to the lung, which composition comprises a plurality of amorphous nanoporous silica particles, in which N-butyloxycarbonyl-3-(4-imidazol-1-yl-methylphenyl)-5-iso-butylthiophene-2-sulfonamide or a pharmaceutically-acceptable salt thereof is loaded into the pores of said silica particles, and wherein the silica particles have: (a) a mass median aerodynamic diameter that is between about 0.1 ?m and about 10 ?m; and (b) a geometric standard deviation that is less than about 4. Such compositions find particular utility in the treatment of an interstitial lung diseases, such as idiopathic pulmonary fibrosis and sarcoidosis, which diseases may be treated with such compositions for example by way of pulmonary administration.

Abstract: According to the invention, there is provided a pharmaceutical composition suitable for administration to the lung, which composition comprises a plurality of amorphous nanoporous silica particles, in which one or more immunomodulatory imide drug is loaded into the pores of said particles, and wherein the silica particles have: (a) a mass median aerodynamic diameter that is between about 0.1 ?m and about 10 ?m; and (b) a geometric standard deviation that is less than about 4, for use in the treatment of an interstitial lung disease by pulmonary administration. Preferred immunomodulatory imide drugs include thalidomide. Interstitial lung diseases that may be mentioned include idiopathic pulmonary fibrosis and sarcoidosis.

Abstract: The present invention relates to a compressed pharmaceutical dosage form comprising one or more active pharmaceutical ingredients at a concentration between 2 and 15% w/w, porous particles, having a diameter between 1 and 100 ?m, at a concentration between 10 and 50% w/w and optionally one or more excipients. The active pharmaceutical ingredient is in admixture with and/or loaded into said particles, whereby a ratio of unloaded versus loaded ingredient is between 100:1 and 1:100. The porosity of the dosage form is more than 5% and less than 45% and the hardness of the dosage form is more than 5 N and less than 30 N using a Schleuniger hardness type tester.
