About Xtampza ER
INDICATION
Xtampza ER is an opioid agonist product 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 Xtampza 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.
Xtampza ER is not indicated as an as-needed (prn) analgesic.
The Full Prescribing Information for Xtampza ER contains the following Boxed Warning:
WARNING: ADDICTION, ABUSE, AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; NEONATAL
OPIOID WITHDRAWAL SYNDROME; and CYTOCHROME P450 3A4 INTERACTION
Addiction, Abuse, and Misuse
Xtampza ER exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and
death. Assess each patient’s risk prior to prescribing Xtampza ER and monitor all patients regularly for the development of
these behaviors or conditions.
Life-Threatening Respiratory Depression
Serious, life-threatening, or fatal respiratory depression may occur with use of Xtampza ER. Monitor for respiratory
depression, especially during initiation of Xtampza ER or following a dose increase.
Accidental Ingestion
Accidental ingestion of even one dose of Xtampza ER, especially by children, can result in a fatal overdose of oxycodone.
Neonatal Opioid Withdrawal Syndrome
Prolonged use of Xtampza ER during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life threatening if
not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is
required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and
ensure that appropriate treatment will be available.
Cytochrome P450 3A4 Interaction
The concomitant use of Xtampza ER with all cytochrome P450 3A4 inhibitors may result in an increase in oxycodone plasma
concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. In
addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in oxycodone plasma
concentration. Monitor patients receiving Xtampza ER and any CYP3A4 inhibitor or inducer.
IMPORTANT SAFETY INFORMATION
Xtampza ER is contraindicated in patients with: significant respiratory depression; acute or severe bronchial asthma in an
unmonitored setting or in the absence of resuscitative equipment; known or suspected gastrointestinal obstruction, including
paralytic ileus; and hypersensitivity (e.g., anaphylaxis) to oxycodone.
Xtampza ER contains oxycodone, a Schedule II controlled substance. As an opioid, Xtampza ER exposes users to the risks of
addiction, abuse, and misuse. As extended-release products, such as Xtampza ER, deliver the opioid over an extended period of time,
there is a greater risk for overdose and death due to the larger amount of oxycodone present.
Potential serious adverse events caused by opioids include addiction, abuse, and misuse, life-threatening respiratory
depression, neonatal opioid withdrawal syndrome, risks of concomitant use or discontinuation of cytochrome P450 3A4 inhibitors and
inducers, risks due to interactions with central nervous system depressants, risk of life-threatening respiratory depression in
patients with chronic pulmonary disease or in elderly, cachectic, or debilitated patients, adrenal insufficiency, severe
hypotension, risks of use in patients with increased intracranial pressure, brain tumors, head injury, or impaired consciousness,
risks of use in patients with gastrointestinal conditions, risk of use in patients with seizure disorders, withdrawal, risks of
driving and operating machinery, and laboratory monitoring.
The most common AEs (>5%) reported by patients in the Phase 3 clinical trial during the titration phase were: nausea
(16.6%), headache (13.9%), constipation (13.0%), somnolence (8.8%), pruritus (7.4%), vomiting (6.4%), and dizziness (5.7%).
