Summary: | 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 µm 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.
La présente invention concerne un procédé de fabrication de particules poreuses de silice comprenant au moins un composé bioactif, les particules étant adaptées pour une administration pulmonaire, nasale, sublinguale et/ou pharyngée dudit au moins un composé bioactif et ayant un diamètre aérodynamique moyen en masse (MMAD) compris entre 0,5 et 15 µm avec un écart type géométrique (GSD) inférieur à 2,5. L'invention concerne également une composition pharmaceutique comprenant lesdites particules de silice et une utilisation des particules de silice dans les diagnostics, la prévention et/ou le traitement de troubles locaux et/ou systémiques, tels que des troubles du poumon, du nez, de la sublinguale et/ou du pharynx. |
