|Pernix Announces the Issuance of Zohydro ER with BeadTek Formulation Patent|
Issuance of U.S. Patent Number 9,132,096 covering the Zohydro ER with BeadTek formulation
MORRISTOWN, NJ – September 24, 2015 – Pernix Therapeutics Holdings, Inc. (NASDAQ: PTX), a specialty pharmaceutical company, today announced that the central patent for Zohydro® ER with BeadTek™, U.S. Patent Number 9,132,096, has issued. The patent covers a formulation of a combination of inactive beads with BeadTek abuse deterrent technology and active hydrocodone beads and expires in September 2034. In addition, Zohydro ER with BeadTek will be added to the U.S. Food and Drug Administration’s (FDA) Approved Drug Products with Therapeutic Equivalence Evaluations (commonly known as “the Orange Book”), which identifies drug products approved on the basis of safety and effectiveness by the FDA.
“The issuance of this patent comes after the launch of Zohydro ER with BeadTek on May 4, 2015 and will be a valuable addition to the growing Zohydro ER patent estate,” said Doug Drysdale, Chairman and CEO of Pernix Therapeutics. “This patent further supports the Pernix commitment to the introduction of products promoting the safe use of opioids for appropriate patients.”
BeadTek is a technology that encompasses an indistinguishable mix of inactive beads, active immediate release hydrocodone beads and active extended-release hydrocodone beads. Zohydro ER with BeadTek was approved on January 30, 2015 by the FDA. Zohydro ER with BeadTek delivers an extended release of hydrocodone that provides 12-hour dose duration. When the medication is taken as directed, the inactive beads contained in Zohydro ER with BeadTek remain inert. The inactive beads dissolve independently of the active hydrocodone beads and are designed not to change the 12-hour release properties of the medication. However, when crushed and dissolved in liquids or solvents, the inactive beads are designed to immediately form a viscous gel.
Zohydro ER with BeadTek is 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 does not contain acetaminophen, unlike many immediate-release hydrocodone products, reducing the risk for potential liver toxicity due to overexposure of acetaminophen. Zohydro ER with BeadTek is available in strengths 10mg, 15 mg, 20mg, 30 mg, 40mg, and 50mg.
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 114 million prescriptions in 2014. 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.

BeadTek technology was developed using safe, well-known excipients and proprietary manufacturing processes to create an inactive ingredient that immediately forms a viscous gel when crushed and dissolved in liquids or solvents. All of the beads within the medication capsule are indistinguishable in color, shape, density and size, and do not impact the drug release profile when taken as directed.

LIMITATIONS OF USE
Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with extended-release opioid formulations, reserve Zohydro ER for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.
Zohydro ER is not indicated as an as needed (prn) analgesic.
Please see the Zohydro ER full prescribing information for the complete boxed warning and safety information.
IMPORTANT SAFETY INFORMATION
Zohydro ER is contraindicated in patients with significant respiratory depression, acute or severe bronchial asthma, known or suspected paralytic ileus, and hypersensitivity to hydrocodone bitartrate.
Zohydro ER has warnings for: interactions with CNS depressants; elderly, cachectic, debilitated patients, and those with chronic pulmonary disease; hypotensive effects; patients with head injury or increased intracranial pressure; and concomitant use of CYP3A4 may increase opioid effects. Please see full prescribing information for the complete warning information.
Potential serious adverse events caused by opioids include addiction, abuse, and misuse; life-threatening respiratory depression; neonatal opioid withdrawal syndrome; interactions with other CNS depressants; hypotensive effects; gastrointestinal conditions, and seizures. The most common adverse reactions associated with Zohydro ER (≥2%) include constipation, nausea, somnolence, fatigue, headache, dizziness, dry mouth, vomiting, pruritus, abdominal pain, peripheral edema, upper respiratory tract infection, muscle spasms, urinary tract infection, back pain, and tremor. With intravenous abuse, the inactive ingredients in Zohydro ER can result in death, local tissue necrosis, infection, pulmonary granulomas, and increased risk of endocarditis and valvular heart injury. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.
