WARNING: RISK OF RESPIRATORY DEPRESSION, MEDICATION ERRORS, ABUSE POTENTIAL
Fatal respiratory depression has occurred in patients treated with FENTORA, including following use in opioid non-tolerant patients and improper dosing.
The substitution of FENTORA for any other fentanyl product may result in fatal overdose.
Due to the risk of respiratory depression, FENTORA is contraindicated in the management of acute or postoperative pain including headache/migraine and in opioid non-tolerant patients.
FENTORA must be kept out of reach of children. [see Patient Counseling Information and How Supplied/Storage and Handling (16.1)
The concomitant use of FENTORA with CYP3A4 inhibitors may result in an increase in fentanyl plasma concentrations, and may cause potentially fatal respiratory depression
[see Drug Interactions]
Substantial differences exist in the pharmacokinetic profile of FENTORA compared to other fentanyl products that result in clinically important differences in the extent of absorption of fentanyl that could result in fatal overdose.
- When prescribing, do not convert patients on a mcg per mcg basis from any other fentanyl products to FENTORA. [see Dosage and Administration (
- When dispensing, do not substitute a FENTORA prescription for other fentanyl products.
FENTORA contains fentanyl, an opioid agonist and a Schedule II controlled substance, with an abuse liability similar to other opioid analgesics. FENTORA can be abused in a manner similar to other opioid agonists, legal or illicit. This should be considered when prescribing or dispensing FENTORA in situations where the physician or pharmacist is concerned about an increased risk of misuse, abuse or diversion.
Because of the risk for misuse, abuse, addiction, and overdose, FENTORA is available only through a restricted program required by the Food and Drug Administration, called a Risk Evaluation and Mitigation Strategy (REMS). Under the Transmucosal Immediate Release Fentanyl (TIRF) REMS Access program, outpatients, healthcare professionals who prescribe to outpatients, pharmacies, and distributors must enroll in the program. [see Warnings and Precautions] Further information is available at www.TIRFREMSAccess.com or by calling 1-866-822-1483.
FENTORA (fentanyl buccal tablet) is a potent opioid analgesic, intended for buccal mucosal administration.
FENTORA is designed to be placed and retained within the buccal cavity for a period sufficient to allow disintegration of the tablet and absorption of fentanyl across the oral mucosa.
FENTORA employs the OraVescent® drug delivery technology, which generates a reaction that releases carbon dioxide when the tablet comes in contact with saliva. It is believed that transient pH changes accompanying the reaction may optimize dissolution (at a lower pH) and membrane permeation (at a higher pH) of fentanyl through the buccal mucosa.
FENTORA is indicated for the management of breakthrough pain in cancer patients 18 years of age and older who are already receiving and who are tolerant to around-the-clock opioid therapy for their underlying persistent cancer pain. Patients considered opioid tolerant are those who are taking around-the-clock medicine consisting of at least 60 mg of oral morphine daily, at least 25 mcg/hr of transdermal fentanyl, at least 30 mg of oral oxycodone daily, at least 8 mg of oral hydromorphone daily, at least 25 mg oral oxymorphone daily, or an equianalgesic dose of another opioid daily for a week or longer. Patients must remain on around-the-clock opioids while taking FENTORA.
This product must not be used in opioid non-tolerant patients because life-threatening hypoventilation and death could occur at any dose in patients not on a chronic regimen of opioids. For this reason, FENTORA is contraindicated in the management of acute or postoperative pain.
FENTORA is intended to be used only in the care of opioid tolerant cancer patients and only by healthcare professionals who are knowledgeable of and skilled in the use of Schedule II opioids to treat cancer pain.
Limitations of Use:
As a part of the TIRF REMS Access program, FENTORA may be dispensed only to outpatients enrolled in the program [see
Warnings and Precautions]. For inpatient administration of FENTORA (e.g., hospitals, hospices, and long-term care facilities that prescribe for inpatient use), patient and prescriber enrollment is not required.

Procedural Pain Treatment With Transmucosal Sublingual Fentanyl Tablet in Colonoscopy Patients [Recruiting]
Colonoscopy is generally considered an invasive procedure that causes remarkable pain to the
patient. The pain associated with the procedure is not caused by the insertion of the scope
but from inflating of the colon in order to do the inspection. It has been shown that
colonoscopy can be performed successfully without sedation (Leung, 2010), but many patients
feel discomfort during the procedure. Factors predicting a painful colonoscopy are
female-gender, degree of patient nervousness and the technical difficulty of the colonoscopy
(Ylinen et al. 2009). Also age under 40, previous abdominal surgery and use of sedation are
associated with painful colonoscopy ( Seip et al. 2009). Most often sedation and/or
analgesia are achieved by administering a benzodiazepine or a combination of a
benzodiazepine and an opioid (Fanti et al. 2009, Maskelar et al. 2009,), dexmedetomidine
(Dere et al. 2009) or by using non-pharmacologic methods (Amer-Cuenca et al. 2011). Tramadol
as monotherapy did not significantly decrease pain intensity or endoscopist's evaluation of
colonoscopy (Grossi et al. 2004). Currently, intravenous midazolam is the drug used most
commonly to introduce some sedation for colonoscopy. Intravenous sedation definitely
increases the cost of procedure; drug administration, need for pulse oximetry monitoring and
the need for follow-up after the procedure make colonoscopy sometimes expensive and
troublesome. It has also been shown, that low-dose midazolam neither relieves discomfort nor
makes patients forget it (Elphick et al. 2009).
Fentanyl is a short-acting opioid widely used in anesthesia management. Transmucosal
sublingual formulation of fentanyl has been developed to further improve the management of
pain. When administered as a sublingual fast-dissolving tablet (Abstral®) that is placed
under the tongue, the effects is fast and predictable. Its active ingredient is absorbed by
the body through the mucous membrane. After administration of buccal fentanyl maximum plasma
drug concentration was measured after 25 minutes (Darwish et al. 2011). Plasma fentanyl
concentrations versus time following buccal and sublingual administration are very similar
(Darwish et al. 2008). Abstral® sublingual tablets should be administered directly under
the tongue at the deepest part. Sublingual administration is an easy and non-invasive
method of pain treatment for the patient coming to colonoscopy done as an office based
procedure. Other advantages compared to invasive methods are improved comfort of patients
and no need for intravenous access because of pain relief. Before, it has been used in the
management of breakthrough pain in cancer patients. Sublingual fentanyl is shown to be
effective and well-tolerated for the treatment of breakthrough cancer pain (Uberall et al.
2011). The use of transmucosal tablet for colonoscopy patients is a quite new approach.
Fentanyl Effect on Blood Pressure in Elderly Patients After Induction of General Anesthesia [Recruiting]
Hypotension is frequently encountered after induction of general anesthesia. It can be
pronounced in elderly patients and can require administration of vasopressor agents
including ephedrine and phenylephrine. Intraoperative hypotension, especially prolonged
episodes, can contribute to an increase in morbidity and mortality in the postoperative
period as suggested by some former studies. The investigators hypothesize that fentanyl can
contribute to the decrease in blood pressure (BP) that is seen after induction of general
anesthesia in older patients. This hypotension may be due to fentanyl blocking effect on the
sympathetic nervous system.
This study will be the first one to examine the effect of fentanyl administration on blood
pressure in elderly patients with induction of general anesthesia prior to the start of
surgery. If the study shows that fentanyl contributes to hypotension during this period, it
may lead to a change in practice and better patient outcomes and mortality rates.
Remifentanil vs Fentanyl During Cardiac Surgery and Chronic Thoracic Pain [Recruiting]
This study will investigate the influence of intra-operative use of remifentanil versus
fentanyl on the percentage of patients with chronic thoracic after cardiac surgery via
sternotomy. Secondary quantitative sensory testing is performed to determine thermal and
electrical detection and pain threshold and the difference in pain variability scoring.
Postoperative pain scores, analgesic use, genetic variances and costs are measured.
Breakthrough Dyspnea Fentanyl Study in Cancer Patients [Completed]
The goal of this clinical research study is to learn if fentanyl given under the skin can

Fentanyl is commonly used for treatment of cancer pain. It is believed to help patients
with their shortness of breath as well.
A placebo is not a drug. It looks like the study drug but is not designed to treat any
disease or illness. It is designed to be compared with a study drug to learn if the study
