Abstract: A process for producing a pharmaceutical powder for inhalation comprising crystalline particles of an inhalation compound, comprising dissolving an inhalation compound in a solvent; and introducing the solution containing the inhalation compound in droplet form or as a jet stream into an anti-solvent which is miscible with the solvent and which is under agitation.

Abstract: New hydrated salts of N,N'-diacetylcystine are described, as well as processes for the preparation thereof.

Abstract: There are described finely divided particles of a pharmaceutical substance, wherein the substance when submitted to water vapor gives off heat of less than 1.2 Joules per gram, processes for their production and pharmaceutical formulations containing them.

Abstract: The present invention relates to a method for the synthesis of foscarnet, i.e. trisodium phosphonoformate hexahydrate, comprising the steps of adding sodium hydroxide to water, heating the aqueous sodium hydroxide solution to 50.degree. C., adding triethyl phosphonoformate to said solution at 50.degree. C., heating the reaction mixture to reflux for about 1 hour, cooling of the reaction mixture and filtering-off of the product.

Abstract: A process for providing water-soluble micronized pharmaceutically acceptable inhalable substances, which can be produced, stored and used while maintaining the aerodynamic properties required for inhalation of the pharmaceutically acceptable substances. This process is carried out by the steps of reducing, if necessary, the residual water from the micronized substance by drying at an elevated temperature and/or vacuum; conditioning the dried, micronized pharmaceutically acceptable inhalable substances with a solvent; and eliminating residual solvent by storing under dry conditions as, e.g., in a vacuum or by purging with a dry, inert gas.

Abstract: The present invention is directed to a process for preparing formoterol and related compounds and derivatives thereof and their pharmacologically and pharmaceutically acceptable fumarate salts and/or solvates. The present invention is also directed to certain formoterol related compounds per se.

Abstract: New crystalline organic salts of N,N'-diacetyl cystine with immunomodulating effect, processes for their preparation, pharmaceutical compositions containing them and methods of their pharmacological use.

Abstract: A method of controlling the epimeric distribution in the preparation of 16,17-acetals of pregnane derivatives characterized in reaction of a corresponding 16,17-acetonide with an aldehyde or ketone in (a) hydrocarbon solvent wherein the solubility of the pregnane derivative is less than 1 mg/l or in a halogenated hydrocarbon solvent together with a hydrohalogen acid or an organic sulphonic acid as catalyst and in the presence of small grains of an insert material in the reaction medium or (b) a halogenated hydrocarbon solvent together with a hydrohalogen acid an organic sulphonic acid as catalyst and in the presence of an epimeric distribution modifier.
