  • Patent number: 8852543
    Abstract: Rare earth metal compounds, particularly lanthanum, cerium, and yttrium, are formed as porous particles and are effective in binding metals, metal ions, and phosphate. A method of making the particles and a method of using the particles is disclosed. The particles may be used in the gastrointestinal tract or the bloodstream to remove phosphate or to treat hyperphosphatemia in mammals. The particles may also be used to remove metals from fluids such as water.

  • Publication number: 20140288143
    Abstract: Therapeutic compositions comprising an indoloquinone compound and various bladder cancer treatments and methods are disclosed. More specifically, bladder cancer treatments include the intravesical administration of apaziquone immediately following transurethral resection. Also disclosed are therapeutic compositions comprising an indoloquinone compound and a formulation vehicle. The formulation vehicle improves the solubility and stability of the indoloquinone compound. Additionally, the coating compositions can include coating agents that provide better adhesion of the coating composition to the bladder wall during intravesical delivery of the coating composition.
