Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Based on data from nine Phase 2/3 studies that administered multiple doses (seven placebo- and/or active-controlled, one noncontrolled and one Phase 3 active-controlled safety study) the most common adverse reactions (reported by ≥10% in any NUCYNTA dose group) were: nausea, dizziness, vomiting and somnolence.
The most common reasons for discontinuation due to adverse reactions in the studies described above (reported by ≥1% in any NUCYNTA dose group) were dizziness (2.6% vs. 0.5%), nausea (2.3% vs. 0.6%), vomiting (1.4% vs. 0.2%), somnolence (1.3% vs. 0.2%) and headache (0.9% vs. 0.2%) for NUCYNTA- and placebo-treated patients, respectively. Seventy-six percent of NUCYNTA-treated patients from the nine studies experienced adverse events.
NUCYNTAwas studied in multiple-dose, active- or placebo-controlled studies, or noncontrolled studies (n = 2178), in single-dose studies (n = 870), in open-label study extension (n = 483) and in Phase 1 studies (n = 597). Of these, 2034 patients were treated with doses of 50 mg to 100 mg of NUCYNTA dosed every 4 to 6 hours.
The data described below reflect exposure to NUCYNTA in 3161 patients, including 449 exposed for 45 days. NUCYNTA was studied primarily in placebo- and active-controlled studies (n = 2266, and n = 2944, respectively). The population was 18 to 85 years old (mean age 46 years), 68% were female, 75% white and 67% were postoperative. Most patients received NUCYNTA doses of 50 mg, 75 mg, or 100 mg every 4 to 6 hours.

The following adverse drug reactions occurred in less than 1% of NUCYNTA-treated patients in the pooled safety data from nine Phase 2/3 clinical studies:
Cardiac disorders: heart rate increased, heart rate decreased
Eye disorders: visual disturbance
Gastrointestinal disorders: abdominal discomfort, impaired gastric emptying
General disorders and administration site conditions: irritability, edema, drug withdrawal syndrome, feeling drunk
Immune system disorders: hypersensitivity
Musculoskeletal and connective tissue disorders: involuntary muscle contractions, sensation of heaviness

Renal and urinary disorders: urinary hesitation, pollakiuria
Respiratory, thoracic and mediastinal disorders: oxygen saturation decreased, cough, dyspnea, respiratory depression
Skin and subcutaneous tissue disorders: urticarial
Vascular disorders: blood pressure decreased
In the pooled safety data, the overall incidence of adverse reactions increased with increased dose of NUCYNTA, as did the percentage of patients with adverse reactions of nausea, dizziness, vomiting, somnolence, and pruritus.
The following additional adverse reactions have been identified during post-approval use of tapentadol. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Gastrointestinal disorders: diarrhea
Nervous system disorders: headache
Psychiatric disorders: hallucination, suicidal ideation, panic attack
Cardiac disorders: palpitations
Serotonin syndrome: Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs.
Adrenal insufficiency: Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use.
Anaphylaxis: Anaphylaxis has been reported with ingredients contained in NUCYNTA oral solution.

Table 2 includes clinically significant drug interactions with NUCYNTA oral solution.
Table 2: Clinically Significant Drug Interactions with NUCYNTA oral solution
|Benzodiazepines and other Central Nervous System (CNS) Depressants|
|Clinical Impact:||Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants including alcohol, increases the risk of respiratory depression, profound sedation, coma, and death.|
|Intervention:||Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients closely for signs of respiratory depression and sedation [see WARNINGS AND PRECAUTIONS].|
|Examples:||Benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol.|
|Clinical Impact:||The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome [see WARNINGS AND PRECAUTIONS].|
|Intervention:||If concomitant use is warranted, carefully observe the patient, particularly during treatment initiation and dose adjustment. Discontinue NUCYNTA oral solution if serotonin syndrome is suspected.|
|Examples:||Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue).|
|Monoamine Oxidase Inhibitors (MAOIs)|
|Clinical Impact:||MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity (e.g., respiratory depression, coma) [see WARNINGS AND PRECAUTIONS]|
|Intervention:||Do not use NUCYNTA oral solution in patients taking MAOIs or within 14 days of stopping such treatment. If urgent use of an opioid is necessary, use test doses and frequent titration of small doses of other opioids (such as oxycodone, hydrocodone, oxymorphone, hydrocodone, or buprenorphine) to treat pain while closely monitoring blood pressure and signs and symptoms of CNS and respiratory depression.|
|Examples:||phenelzine, tranylcypromine, linezolid|
|Mixed Agonist/Antagonist and Partial Agonist Opioid Analgesics|
|Clinical Impact:||May reduce the analgesic effect of NUCYNTA oral solution and/or precipitate withdrawal symptoms.|
|Intervention:||Avoid concomitant use.|
|Examples:||butorphanol, nalbuphine, pentazocine, buprenorphine|
|Clinical Impact:||Tapentadol may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression.|
|Intervention:||Monitor patients for signs of respiratory depression that may be greater than otherwise expected and decrease the dosage of NUCYNTA oral solution and/or the muscle relaxant as necessary.|
|Clinical Impact:||Opioids can reduce the efficacy of diuretics by inducing the release of antidiuretic hormone.|
|Intervention:||Monitor patients for signs of diminished diuresis and/or effects on blood pressure and increase the dosage of the diuretic as needed.|
|Clinical Impact:||The concomitant use of anticholinergic drugs may increase risk of urinary retention and/or severe constipation, which may lead to paralytic ileus.|
|Intervention:||Monitor patients for signs of urinary retention or reduced gastric motility when NUCYNTA oral solution is used concomitantly with anticholinergic drugs.|
|Alcohol, Other Opioids, and Drugs of Abuse|
|Clinical Impact:||Due to its mu-opioid agonist activity, NUCYNTAoral solution may be expected to have additive effects when used in conjunction with alcohol, other opioids, or illicit drugs that cause central nervous system depression, respiratory depression, hypotension, and profound sedation, coma or death [see WARNINGS AND PRECAUTIONS].|
|Intervention:||Instruct patients not to consume alcoholic beverages or use prescription or non-prescription products containing alcohol, other opioids, or drugs of abuse while on NUCYNTA oral solution therapy.|
|Examples:||Alcohol, other opioids, illicit drugs|
Drug Abuse And Dependence
NUCYNTAoral solution contains tapentadol, a Schedule II controlled substance.
NUCYNTA oral solution contains tapentadol, a substance with a high potential for abuse similar to other opioids including fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxycodone, and oxymorphone. NUCYNTA can be abused and is subject to misuse, addiction, and criminal diversion [see WARNINGS AND PRECAUTIONS].
All patients treated with opioids require careful monitoring for signs of abuse and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use.
All patients treated with opioids require careful monitoring for signs of abuse and addiction, since use of opioid analgesic products carries the risk of addiction even under appropriate medical use.
Prescription drug abuse is the intentional non-therapeutic use of a prescription drug, even once, for its rewarding psychological or physiological effects.
Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: a strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful consequences, a higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes a physical withdrawal.
“Drug seeking” behavior is very common in persons with substance use disorders. Drug-seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing or referral, repeated “loss” of prescriptions, tampering with prescriptions, and reluctance to provide prior medical records or contact information for other treating health care provider (s). “Doctor shopping” (visiting multiple prescribers to obtain additional prescriptions) is common among drug abusers and people suffering from untreated addiction Preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control.
Abuse and addiction are separate and distinct from physical dependence and tolerance. Health care providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. In addition, abuse of opioids can occur in the absence of true addiction.
NUCYNTA oral solution like other opioids, can be diverted for non-medical use into illicit channels of distribution. Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests, as required by law, is strongly advised.
Proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.
Risks Specific To Abuse Of NUCYNTA
NUCYNTA oral solution is for oral use only. Abuse of NUCYNTA oral solution poses a risk of overdose and death. The risk is increased with concurrent abuse of NUCYNTA oral solution with alcohol and other central nervous system depressants.
Both tolerance and physical dependence can develop during chronic opioid therapy. Tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia (in the absence of disease progression or other external factors). Tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects.
Physical dependence results in withdrawal symptoms after abrupt discontinuation or a significant dosage reduction of a drug. Withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity ( e.g., naloxone, nalmefene), or mixed agonist/antagonist analgesics (e.g., pentazocine, butorphanol, nalbuphine) or partial agonists (e.g., buprenorphine). Physical dependence may not occur to a clinically significant degree until after several days to weeks of continued opioid usage.
NUCYNTA oral solution should not be abruptly discontinued in a physically-dependent patient [see DOSAGE AND ADMINISTRATION]. If NUCYNTA oral solution is abruptly discontinued in a physically-dependent patient, a withdrawal syndrome may occur. Some or all of the following can characterize this syndrome: restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis Other signs and symptoms also may develop, including: irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate.
Infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal symptoms [see Use In Specific Populations].
