  • Patent number: 5455047
    Abstract: A directly compressed cholestyramine tablet with a solvent-free coating is disclosed. The inner core of the tablet is made up of cholestyramine agglomerates consisting of numerous small, irregularly-shaped, jagged-edged fragments having relatively few smooth or flat surfaces with a moisture content ranging from about 8 to 14 percent by weight. A process is also disclosed for preparing cholestyramine agglomerates of the invention. The solvent-free coating comprises from about 60 percent to about 95 percent by weight of stearic acid and from about 5 percent to about 40 percent of polyethylene glycol.
    Type: Grant

  • Patent number: 5413995
    Abstract: A lyophilized pharmaceutical solid composition containing cyclophosphamide for reconstitution with water to provide a solution for oral or parenteral administration. This lyophilized cyclophosphamide solid composition demonstrates improved stability, solubility characteristics and enhanced appearance compared with currently available dry powder pre-mix compositions of cyclophosphamide. The lyophilized solid composition contains about 20 parts by weight of cyclophosphamide, about 11/4-2 parts by weight of water and from about 10-85 parts by weight of excipient which is comprised mainly of mannitol. Processes for making the composition are disclosed.
