Patents by Inventor Phillip E. McDonald

Phillip E. McDonald has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9775800
    Abstract: Effective treatments of pain that accompanies post-operative surgeries are provided. Through the administration of an effective amount of a combination of bupivacaine and clonidine at or near a target site, one can alleviate or prevent pain. This administration of bupivacaine and clonidine or pharmaceutically acceptable salts thereof is particularly useful following surgery.
    Type: Grant

    Date of Patent: October 3, 2017
    Assignee: Warsaw Orthopedic, Inc.
    Inventors: Phillip E. McDonald, Amira Wohabrebbi, Christopher M. Hobot, Vanja M. King
  • Patent number: 9770438
    Abstract: Effective treatments of acute pain for extended periods of time are provided. The treatments include the administration of one or more drug depots at or near a target site wherein the drug depots include an effective amount of clonidine formulated within a polyorthoester. By administration of one or more drug depots at or near the target site, one can relieve pain caused by diverse sources, including but not limited to spinal disc herniation (i.e. sciatica), spondilothesis, stenosis, discongenic back pain and joint pain, as well as pain that is incidental to surgery. In some embodiments, the relief can be for at least twenty-five days, at least fifty days, at least one hundred days or at least one hundred and thirty-five days.

  • Patent number: 9005634
    Abstract: A pharmaceutical depot includes a biodegradable polymer having a glass transition temperature of 20 degrees centigrade or less and at least 25% wt solid particles suspended in the biodegradable polymer. The pharmaceutical depot also includes a post-operative pain relieving therapeutic agent.

  • Patent number: 8999368
    Abstract: The implant design is a drug loaded polymer device, such as a rod, designed to control the release of a biologically active agent, such as clonidine or its derivatives, such as clonidine HCl for a prolonged period of time, such as 2 months, 3 months, 4 months, and even 4.5 months. The polymer is preferably a biodegradable polymer, such as poly(lactide-co-glycolide) or polylactic acid/polylactide. The challenge in using the HCl salt forms of drugs such as clonidine, is controlling the release of the highly water soluble drug for up to 4.5 months. It has been found that by controlling the particle size distribution of the drug powder, the drug distribution within the polymer matrix is more uniform and can be controlled. Therefore, the large aggregates, which cause rapid drug release can be eliminated.
