  • Patent number: 7795205
    Abstract: The present invention relates generally to methods of inhibiting angiogenesis in a patient by administering an effective angiogenesis-inhibiting amount of a thrombin inhibitor, and to the treatment of disease states that result from uncontrolled cell proliferation by administering a thrombin inhibitor alone or co-administering a thrombin inhibitor with an anticancer or cytotoxic agent. Specifically, the thrombin inhibitors used in the methods of the present invention are hirudins.

  • Publication number: 20040161459
    Abstract: The current invention relies on a process already provided in great detail in U.S. Pat. No. 60/437,507 and an associated CIP filed on May 23, 2003 and hereby incorporated by reference. However, it was noted during additional studies that if the Cushioning Beads™ were milled to a particle size between about 10 mesh and about 50 mesh and to a most preferred size of 30-40 mesh, the Cushioning Beads™ did not loose their ability to protect coated particles during compression, as would be expected because of the fine milling. Moreover, it was also discovered that tablets compressed from the milled Cushioning Beads™ immediately disperse in the mouth. A final advantage of the current invention is the improved hardness and friability. The invention produces a tablet of 2Kp or 20N hardness. A vast improvement because it allows for use of conventional manufacturing and packaging equipment.

  • Publication number: 20040126422
    Abstract: The new process can be summarized in five general phases: the manufacture and coating of active-loaded beads with a sustained release coat, an enteric coat; a colonic coat, or a taste-masking coat; the manufacture of the cushioning components the co-processing of active-loaded beads with cushioning components into a single component known as a Cushioning Bead™; the use of freeze-drying to produce the intended outcome, and the compression of the resultant Cushioning Beads™ into tablets.

  • Patent number: 6019988
    Abstract: The invention provides methods and means for enhancing the epidermal, transdermal and dermal permeation of a topically applied pharmacologically active agent (e.g., a drug or medicament) which has a low rate of skin penetration in the absence of a permeation enhancer and which is unstable and degrades during long-term storage with particular permeation enhancers. Also provided by the invention are methods and means to increase the skin penetration of a pharmacologically active agent which has a normally low rate of skin permeation and causes the instability and degradation of a permeation enhancer with which it is combined over a long period of time. Provided by the invention are at least one first composition containing a drug, a pharmaceutically acceptable salt, chemical derivative or formulation thereof, in a dermatologically acceptable vehicle, and at least one second composition containing a permeation enhancer in an acceptable vehicle.
