6.1 Clinical Trials Experience Adult Clinical Trial 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.

A total of 591 patients were treated with oxymorphone hydrochloride tablets in controlled clinical trials.

The clinical trials consisted of patients with acute postoperative pain (n=557) and cancer pain (n=34) trials.

The following table lists adverse reactions that were reported in at least 2% of patients receiving oxymorphone hydrochloride tablets in placebo-controlled trials (acute postoperative pain (N=557).

The common (≥1% - <10%) adverse drug reactions reported at least once by patients treated with oxymorphone hydrochloride tablets in the clinical trials organized by MedDRA’s (Medical Dictionary for Regulatory Activities) System Organ Class were and not represented in Table 1: Cardiac disorders : tachycardia Gastrointestinal disorders : dry mouth, abdominal distention, and flatulence General disorders and administration site conditions : sweating increased Nervous system disorders : anxiety and sedation Respiratory, thoracic and mediastinal disorders : hypoxia Vascular disorders : hypotension Other less common adverse reactions known with opioid treatment that were seen <1% in the oxymorphone hydrochloride tablets trials includes the following: Abdominal pain, ileus, diarrhea, agitation, disorientation, restlessness, feeling jittery, hypersensitivity, allergic reactions, bradycardia, central nervous system depression, depressed level of consciousness, lethargy, mental impairment, mental status changes, fatigue, depression, clamminess, flushing, hot flashes, dehydration, dermatitis, dyspepsia, dysphoria, edema, euphoric mood, hallucination, hypertension, insomnia, miosis, nervousness, palpitation, postural hypotension, syncope, dyspnea, respiratory depression, respiratory distress, respiratory rate decreased, oxygen saturation decreased, difficult micturition, urinary retention, urticaria, vision blurred, visual disturbances, weakness, appetite decreased, and weight decreased.

Table 1 6.2 Post-marketing Experience The following adverse reactions have been identified during post approval use of opioids.

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.
