MORRISTOWN, N.J., Sept. 14, 2016 (GLOBE NEWSWIRE) -- Pernix Therapeutics Holdings, Inc. (NASDAQ:PTX), a specialty pharmaceutical company, today announced that the United States Patent and Trademark Office has issued U.S. Patent Numbers 9,421,200 (‘200 patent) and 9,433,619 (‘619 patent), covering important safety information related to dosing patients with Zohydro® ER with BeadTek™. These patents, in addition to recently issued U.S. Patent Numbers 9,265,760 (‘760 patent), 9,326,982 (‘982 patent), 9,333,201 (‘201 patent) and 9,339,499 (‘499 patent), are broadly directed to methods of dosing patients with mild or moderate hepatic impairment with hydrocodone.  The ‘760, ‘982, ‘201, ‘499, ‘200, and ‘619 patents expire on July 25, 2033.

“The ‘200 and ‘619 patents, solely owned by Pernix, further strengthen our intellectual property portfolio covering Zohydro ER with BeadTek,” said John Sedor, Chairman and CEO of Pernix Therapeutics.  “With the addition of these patents, Zohydro ER with BeadTek currently has nine patents listed in the FDA’s Orange Book: Approved Drug Products with Therapeutic Equivalence Evaluations. In addition, several other patent applications related to this product are pending.”

About Zohydro ER with BeadTek
Zohydro ER with BeadTek is an extended-release form of hydrocodone indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Zohydro ER with BeadTek does not contain acetaminophen, unlike many immediate-release hydrocodone products, reducing the risk for potential liver toxicity due to overexposure of acetaminophen. The active ingredient, hydrocodone, is the most commonly prescribed opioid in the U.S., with over 90 million prescriptions in 2015. Zohydro ER with BeadTek is an opioid agonist, extended-release, oral formulation of hydrocodone bitartrate containing technology that contains an inactive ingredient that immediately forms a viscous gel when crushed and dissolved in liquids or solvents.  As covered by the ‘760, ‘982, ‘201, ‘499, ‘200 and ‘619 patents, no adjustment in starting dose for Zohydro ER is required for patients with mild or moderate hepatic impairment.  Zohydro ER with BeadTek is available in strengths 10mg, 15 mg, 20mg, 30 mg, 40mg, and 50mg.
