Abstract: Solid oral dosage forms, especially tablets, of a pharmaceutical composition comprising a supramolecular complex can be formed from a direct compression process or a compaction process such as roller compaction. Such solid oral dosage forms feature an immediate release profile that allows for fast release of the therapeutic agent. A particularly useful supramolecular complex is trisodium [3-((1S,3R)-1-biphenyl-4-ylmethyl-3-ethoxycarbonyl-1-butylcarbamoyl) propionate-(S)-3?-methyl-2?-(pentanoyl{2?-(tetrazol-5-ylate)biphenyl-4?-ylmethyl}amino)butyrate]hemipentahydrate.

Abstract: A composite metal article provided in the present invention includes a carbon steel core and a dissimilar composite metal out-layer, said out-layer combined with the carbon steel core by high pressure forging. As the high pressure forging belongs to the precise forging type, which molded by the method of inpour the metal liquid into the cavity on high pressure, thus it can form a thin composite out-layer out of the carbon steel core; it can combined a composite out-layer with the complex structure carbon steel core thus form a complex structure railing and metal table/chair etc.; it can combined complex structure composite out-layer with the simplex structure carbon steel core thus form a complex structure railings and metal table/chair etc.; as there are no air holes on the composite out-layer surface, it has a precise and nice-looking surface and can manufacture products by a simple post-processing.

Abstract: The present invention provides a system and a method for the production of microparticles and nanoparticles of materials that can be dissolved. The system and method of the present invention provide quicker freezing times, which in turn produces a more uniform distribution of particle sizes, smaller particles, particles with increased porosity and a more intimate mixing of the particle components. The system and method of the present invention also produce particles with greater surface area than conventional methods. One form of the present invention provides a method for the preparation of particles. An effective ingredient is mixed with water, one or more solvents, or a combination thereof, and the resulting mixture is sprayed through an insulating nozzle located at or below the level of a cryogenic liquid. The spray generates frozen particles.
