    摘要: Porous cellulose matrices with a defined particle size and a significantly higher porosity (i.e. pore volume) than conventional formulations, such as pellet formulations containing cellulose and binders are prepared. The cellulose is mechanically treated with low adhesion to the process equipment during a controlled gradual addition of an aqueous based fluid, optionally containing a surface-active ingredient, into regular particles, which are finally dried to obtain dry porous cellulose matrices. The so obtained matrices can be used as carriers for bioactive substances in multiple-unit preparations or tablets.

    摘要: A pharmaceutical composition, constituting a spray suspension includes at least one liquid excipient and at least one solid excipient substantially insoluble in the liquid excipient, and at least one pharmaceutical active ingredient. A method of preparing porous suspension particles includes: a) wet-milling or dry-milling the solid excipient(s) or a mixture of at least one active ingredient and a solid excipient(s) in a milling equipment inducing essentially compression and shear forces, resulting in fine particulate quality, where more than 90% by weight is smaller than 5 m; b) drying and aggregating the product of step a) alone or with the addition of at least one active ingredient, in fine particulate form, which will produce essentially isodiametrical aggregate particles. A suspension particles obtainable by the method pharmaceutical preparation, utilising the composition or porous suspension particles and a method for treatment of disorders using the preparation are disclosed.
