Patent number: 8349819Abstract: A process in which urine is optionally filtered to remove solid extraneous matter and optionally treated so as to reduce the phenolic content of the urine to give and the resulting fluid is then subjected to a solid extraction of the major concentration steroids content therefrom by a first suitable resin (to yield a first resin laden with major concentration steroids and a minor concentration steroid laden first liquid remainder). The minor concentration steroid liquid remainder is subjected to a solid extraction of the minor concentration steroid content therefrom by a second suitable resin (to yield a second resin laden with minor concentration steroids and a second liquid remainder). The first and second resins laden with their respective steroids are then eluted and the eluates are collected separately and optionally subjected to further purification and chromatographic separations, with each resulting separate collection being analyzed for the steroid content thereof.Type: GrantFiled: February 10, 2005Date of Patent: January 8, 2013Assignee: Dr. Reddy's Laboratories New York, Inc.Inventors: John Lomans, Carmen Leiva-paredes

Patent number: 6660725Abstract: Methods for modulating amyloid deposition in a subject are described. An effective amount of at least one ATP binding cassette (ABC) transporter blocker is administered to a subject, such that modulation of amyloid deposition occurs. Methods also include administering and effective amount of at least one ABC transporter blocker, or a pharmaceutically acceptable salt thereof, to a subject such that a disease state associated with amyloidosis is treated. Packaged pharmaceutical compositions for treating amyloidosis are described. The package includes a container for holding an effective amount of a pharmaceutical composition and instructions for using the pharmaceutical composition for treatment of amyloidosis. The pharmaceutical composition includes at least one ABC blocker for modulating amyloid deposition in a subject. Methods for identifying agents which modulate amyloid deposition in a subject are also described.Type: GrantFiled: August 22, 2000Date of Patent: December 9, 2003Assignee: The University of British ColumbiaInventors: Peter B. Reiner, Fred Chiu-lai Lam

Patent number: 6066292Abstract: The invention is directed to a method for sterilizing a pharmaceutical formulation comprising a suspension of a water-insoluble pharmaceutical, comprising the steps of heat-sterilizing an aqueous solution of a viscosity enhancer, to result in a first sterile pre-mix. Next is sterile-filtering an aqueous solution of a mixture of a pharmaceutically-active compound, which results in a second sterile pre-mix. Next is heat-sterilizing a mixture of water, a water-insoluble pharmaceutical, and at least a partial amount of an electrolyte to provide a sub-saturated solution of the electrolyte, and adding under aseptic conditions an aqueous surfactant, to give a third sterile pre-mix. Finally, combining all three pre-mixes in sterile fashion to achieve a sterile suspended pharmaceutical formulation. Thus, for the third pre-mix, use of either Sodium chloride (in varying proportion) or Sodium acetate (in one proportion, but not limited to) is given as an example.Type: GrantFiled: December 19, 1997Date of Patent: May 23, 2000Assignee: Bayer CorporationInventor: Shivaji Purwar
