Abstract: The present invention is concerned with pseudopolymorphic forms of 1-(4-carbazolyloxy)-3-[2-(2-methoxyphenoxy)ethylamino]-2-propanole (carvedilol) or of optically active forms or pharmaceutically acceptable salts thereof, processes for the preparation thereof and pharmaceutical compositions containing them.

Abstract: The present invention is concerned with pharmaceutically acceptable compositions comprising carvedilol or a pharmaceutically acceptable salt thereof distributed as a molecular dispersion in a concentration above 5% (wt./wt.), as well as pharmaceutical administration forms comprising such compositions and their use for the treatment and/or prophylaxis of illnesses such as hypertension, cardiac insufficiency or angina pectoris.

Abstract: 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.

Abstract: The present invention is concerned with pharmaceutically acceptable solutions of carvedilol or pharmaceutically acceptable salts thereof containing adjuvants with lipophilic character, with the carvedilol content lying above 5% (wt./wt., based on the solution) and the carvedilol being distributed in the solution as a molecular dispersion, as well as pharmaceutical administration forms containing such solutions and their use for the treatment and/or prophylaxis of illnesses, such as hypertension, cardiac insufficiency or angina pectoris.

Abstract: 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.

Abstract: 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.

Abstract: 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.
