|Results of Long-Term, Open-Label Study Published in the Journal of Pain Research Demonstrate the Safety, Tolerability and Effectiveness of Zohydro(R) ER|
The safety and tolerability profile of Zohydro ER observed in this study was consistent with the Phase 3 pivotal efficacy study of Zohydro ER and is comparable with other opioid analgesics. The most common adverse events (AEs) observed during the 48-week maintenance phase were constipation (12.5%), back pain (11.1%), nausea (9.9%), and vomiting (9.7%). Effectiveness, a secondary endpoint, showed the majority (55%) of subjects treated with Zohydro ER dosed every 12 hours for up to one year had a clinically meaningful improvement in pain scores (≥ 30% reduction in average daily pain intensity). Secondary outcomes also demonstrated improvements in function, depression, and anxiety assessments.
"People living with severe, chronic pain need effective medications that have demonstrated safety profiles over extended periods of time," said Srinivas Nalamachu, MD, president and medical director,
Zohydro ER is an extended-release opioid agonist 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 was developed to reduce the number of hydrocodone doses per day and to eliminate acetaminophen, an added ingredient in immediate-release hydrocodone combination products, which can put patients at risk for liver toxicity when taken chronically and at high doses.
"In addition to needing options for chronic pain patients who are at risk for acetaminophen toxicity, prescribers may need to switch opioids if their patient's current opioid treatment becomes inadequate either due to loss of pain relief or increasing side effects," said
About the Long-Term Safety Study
This one-year, open-label multicenter study started with a conversion/titration phase of ≤6 weeks in which subjects (n=638) were converted to individualized doses of Zohydro ER every 12 hours, followed by a 48-week maintenance phase (n=424). Safety and tolerability, the primary objective, and long-term effectiveness (as measured by change in average pain score; 0=no pain, 10=worst pain imaginable), the secondary objective, were monitored throughout the study. Depression, anxiety and function were also assessed during the study and reported as secondary outcomes.
About Zohydro® ER
Zohydro® ER is an extended-release opioid agonist 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.
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.

WARNING: ADDICTION, ABUSE AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; NEONATAL OPIOID WITHDRAWAL SYNDROME; INTERACTION WITH ALCOHOL; and CYTOCHROME P450 3A4 INTERACTION

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 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.
