The invention relates to a process for the preparation of fast-dissolving pharmaceutical preparations from difficultly soluble active substances, wherein an aqueous suspension is made from the active substance and one or more water-soluble adjuvants and then the resulting aqueous suspension is processed, with removal of the water, by methods conventional per se, to form solid pharmaceutical preparations. The invention also relates to fast-dissolving pharmaceutical preparations of active substances having a dissolution rate of at least 70% after 30 minutes, prepared in accordance with the process of the invention.

The present invention relates to a rapid and readily reproducible process for stabilizing biologically active substances by combining the biologically active substance witha a stabilizingmixture and drying the resulting mixture into a dry, amorphous product by means of convection drying. The invention also relates to the amorphous, microscopically homogeneous products which are obtained by this process, are in the form of powders and have a uniform geometric, in particular spherical, shape. The invention furthermore relates to the use of substance mixtures for stabilizing biologically active material, in particular proteins by means of spray drying.

Method of stabilizing biologically active substances

The present invention concerns solid instant-release forms of administration (IR form of administration) comprising therapeutic active substances or active substance concentrates in particular lipid conjugates of nucleosides which have gel-forming properties in aqueous media as well as processes for their production.

Solid instant-release forms of administration and process for producing the same

Process for the preparation of shaped, compressed controlled-release unit-dosage forms from a therapeutic active substance exhibiting a self-retarding release that depends on the magnitude of the force used for the compression. The process gives unit-dosage forms for which the release of the active substance is highly uniform, reproducibly identical and largely linear. To achieve this, the active substance and an additive charge that inhibits or compensates for the self-retardation of its release are processed into particles in the first stage of production, so that the preliminary compressed objects made from these particles without any further additives exhibit a rapid release (in comparison with the required controlled release) over the range of the force of compression envisaged for the production of the unit-dosage form in question, after which the particles are compressed in the second stage of production with a release-retarding agent to obtain the unit-dosage forms. The invention also relates to the unit-dosage forms thus obtained.

Process for the preparation of shaped, compressed controlled-release

The present invention provides a composition containing guar flour in the form of tablets for oral administration, said tablets having been produced by dry pressing guar flour with a particle size of 60 to 500 .mu.m. in admixture with 5 to 30% of highly dispersed silica gel.
