6.1 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.
CONZIP capsules were administered to a total of 1987 patients in clinical trials.
These included four double-blind and one long-term, open-label study in patients with osteoarthritis of the hip and knee.
A total of 812 patients were 65 years or older.
Adverse reactions with doses from 100 mg to 300 mg in the four pooled, randomized, double-blind, placebo-controlled studies in patients with chronic non-malignant pain are presented in the following table (see Table 1 ).

The lists below include adverse reactions not otherwise noted in Table 1.
Adverse reactions with incidence rates of 1.0% to <5.0% Cardiac disorders: hypertension Gastrointestinal disorders: dyspepsia, flatulence General disorders: abdominal pain, accidental injury, chills, fever, flu syndrome, neck pain, pelvic pain Investigations: hyperglycemia, urine abnormality Metabolism and nutrition disorders: peripheral edema, weight loss Musculoskeletal, connective tissue and bone disorders: myalgia Nervous system disorders: paresthesia, tremor, withdrawal syndrome Psychiatric disorders: agitation, anxiety, apathy, confusion, depersonalization, depression, euphoria, nervousness Respiratory, thoracic and mediastinal disorders: bronchitis, pharyngitis, rhinitis, sinusitis Skin and subcutaneous tissue disorders: rash Urogenital disorders: prostatic disorder, urinary tract infection Vascular disorders: vasodilatation Adverse reactions with incidence rates of 0.5% to <1.0% at any dose and serious adverse reactions reported in at least two patients Cardiac disorders: EKG abnormal, hypotension, tachycardia Gastrointestinal disorders: gastroenteritis General disorders: neck rigidity, viral infection Hematologic/Lymphatic disorders: anemia, ecchymoses Metabolism and nutrition disorders: blood urea nitrogen increased, GGT increased, gout, SGPT increased Musculoskeletal disorders: arthritis, arthrosis, joint disorder, leg cramps Nervous system disorders: emotional lability, hyperkinesia, hypertonia, thinking abnormal, twitching, vertigo Respiratory disorders: pneumonia Skin and subcutaneous tissue disorders: hair disorder, skin disorder, urticaria Special Senses: eye disorder, lacrimation disorder Urogenital disorders: cystitis, dysuria, sexual function abnormality, urinary retention 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of tramadol.
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.
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 CONZIP.
Androgen deficiency : Cases of androgen deficiency have occurred with use of opioids for an extended period of time [see Clinical Pharmacology (12.2) ] .
Hyperalgesia and Allodynia: Cases of hyperalgesia and allodynia have been reported with opioid therapy of any duration [see Warnings and Precautions (5.8) ].
QT prolongation/torsade de pointes : Cases of QT prolongation and/or torsade de pointes have been reported with tramadol use.
Many of these cases were reported in patients taking another drug labeled for QT prolongation, in patients with a risk factor for QT prolongation (e.g., hypokalemia), or in overdose setting.
Metabolism and nutrition disorders Hyponatremia: Cases of severe hyponatremia and/or SIADH have been reported in patients taking tramadol, most often in females over the age of 65, and within the first week of therapy [see Warnings and Precautions (5.20) ] .
Hypoglycemia: Cases of hypoglycemia have been reported in patients taking tramadol.
Most reports were in patients with predisposing risk factors, including diabetes or renal insufficiency, or in elderly patients [see Warnings and Precautions (5.21) ] .
Opioid-induced esophageal dysfunction (OIED): Cases of OIED have been reported in patients taking opioids, and may occur more frequently in patients taking higher doses of opioid, and/or in patients taking opioids longer term [see Warnings and Precautions (5.16) ].
Adverse Reactions from Observational Studies A prospective, observational cohort study estimated the risks of addiction, abuse, and misuse in patients initiating long-term use of Schedule II opioid analgesics between 2017 and 2021.
Study participants included in one or more analyses had been enrolled in selected insurance plans or health systems for at least one year, were free of at least one outcome at baseline, completed a minimum number of follow-up assessments, and either: 1) filled multiple extended-release/long-acting opioid analgesic prescriptions during a 90 day period (n=978); or 2) filled any Schedule II opioid analgesic prescriptions covering at least 70 of 90 days (n=1,244).
Those included also had no dispensing of the qualifying opioids in the previous 6 months.
Over 12 months: approximately 1% to 6% of participants across the two cohorts newly met criteria for addiction, as assessed with two validated interview-based measures of moderate-to-severe opioid use disorder based on Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria, and approximately 9% and 22% of participants across the two cohorts newly met criteria for prescription opioid abuse and misuse [defined in Drug Abuse and Dependence (9.2)], respectively, as measured with a validated self-reported instrument.
A retrospective, observational cohort study estimated the risk of opioid-involved overdose or opioid overdose-related death in patients with new long-term use of Schedule II opioid analgesics from 2006 through 2016 (n=220,249).
Included patients had been enrolled in either one of two commercial insurance programs, one managed care program, or one Medicaid program for at least 9 months.
New long-term use was defined as having Schedule II opioid analgesic prescriptions covering at least 70 days' supply over the 3 months prior to study entry and none during the preceding 6 months.
Patients were excluded if they had an opioid-involved overdose in the 9 months prior to study entry.
Overdose was measured using a validated medical code-based algorithm with linkage to the National Death Index database.
The 5-year cumulative incidence estimates for opioid-involved overdose or opioid overdose-related death ranged from approximately 1.5% to 4% across study sites, counting only the first event during follow-up.
Approximately 17% of first opioid overdoses observed over the entire study period (5-11 years, depending on the study site) were fatal.
Higher baseline opioid dose was the strongest and most consistent predictor of opioid-involved overdose or opioid overdose-related death.
Study exclusion criteria may have selected patients at lower risk of overdose, and substantial loss to follow-up (approximately 80%) also may have biased estimates.
The risk estimates from the studies described above may not be generalizable to all patients receiving opioid analgesics, such as those with exposures shorter or longer than the duration evaluated in the studies.
