  • Patent number: 6645988
    Abstract: The present invention relates to pharmaceutical preparations comprising substituted benzimidazole proton pump inhibitors. There is provided a liquid or solid pharmaceutical dosage form that is not enteric coated or delayed released containing a proton pump inhibitor and a Primary Essential Buffer. When the dosage form is placed in a liquid phase the Primary Essential Buffer maintains the pH of the environment at a value greater than the pKa of the proton pump inhibitor for a time sufficient to substantially avoid acid degradation of the proton pump inhibitor in the environment. Also provided is a method for treating acid-related gastrointestinal disorders by administering a solid pharmaceutical dosage form; and a kit for the preparation of a liquid oral pharmaceutical composition.

  • Patent number: 6172057
    Abstract: Matrix metalloproteinases (MMPs) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF-&agr; converting enzyme (TACE), a pro-inflammatory cytokine, catalyzes the formation of TNF-&agr; from membrane bound TNF-&agr; precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states. The present invention provides low molecular weight, non-peptide inhibitors of matrix metalloproteinases (MMPs) and TNF-&agr; converting enzyme (TACE) for the treatment of arthritis, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, bone disease, diabetes (insulin resistance) and HIV infection.
