  • Patent number: 8476310
    Abstract: Pharmaceutical formulations comprising docetaxel, solubilizer, and ?-lipoic acid, wherein the formulation is substantially free of polysorbates and polyethoxylated castor oil. The solubilizer may comprise glycofurol, acetic acid, benzyl alcohol, or ethanol. The ?-lipoic acid, at certain concentrations, may impart stability and prevent degradation of docetaxel while the formulations are in storage. The formulations may be combined with a diluent, which comprises one or more hydrotropes such as tocopherol polyethylene glycol succinate and polyethylene glycol. The formulations combined with the diluent also exhibit stability after storage. Methods of administering docetaxel comprise preparing the formulation comprising docetaxel, solubilizer, and ?-lipoic acid; mixing the formulation with a diluent; diluting the resulting formulation in saline, water for injection, or the like; and then injecting the formulations into patients in need thereof.

  • Publication number: 20070190085
    Abstract: The present invention is generally related to alcohol free, liquid ranitidine formulations for oral administration. In particular, the present invention is related to stable, syrup formulations having ranitidine as an active ingredient for oral administration, processes for making the same, and methods of their use. The ranitidine of the present invention is stable in non-polar media or media having a relatively low polarity such that the dielectric constant is less than about 60, and is achieved by using certain saccharides, certain relatively high molecular weight starches, and/or certain celluloses instead of alcohol.
