Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 21 to 64 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Age 21 through 64 years of age: This is a study of adult ED patients.
  • Pain with onset within 7 days: Pain within seven days is the definition of acute pain that has been used in the ED literature.
  • ED attending physician's judgment that the patient's pain warrants IV opioids.
  • ED attending physician's judgment that the patient has capacity to provide informed consent.
  • Patients must be able to understand English or Spanish.

Who cannot join

  • Use of opioids or tramadol within past 24 hours.
  • Use of acetaminophen or non-steroidal anti-inflammatory medication within the previous 8 hours.
  • Prior adverse reaction to opioids or acetaminophen.
  • Chronic pain syndrome: frequently recurrent or daily pain for at least 3 months results in modulation of pain perception which is thought to be due to down-regulation of pain receptors. Examples of chronic pain syndromes include sickle cell anemia, osteoarthritis, fibromyalgia, and peripheral neuropathies.
  • Medical condition that might affect metabolism or opioid analgesics or acetaminophen such as hepatitis, renal insufficiency or failure, hypo- or hyper-thyroidism, Addison's or Cushing's disease
  • Pregnant or breastfeeding
Show all 14Show fewer
  • Alcohol intoxication: the presence of alcohol intoxication as judged by the treating physician may alter pain perception.
  • SBP <100 mmHg: Opioids can produce peripheral vasodilation that may result in orthostatic hypotension.
  • HR < 60/min: Opioids can cause bradycardia.
  • Oxygen saturation < 95% on room air: For this study, oxygen saturation must be 95% or above on room air in order to be enrolled.
  • Use of MAO inhibitors in past 30 days: MAO inhibitors have been reported to intensify the effects of at least one opioid drug causing anxiety, confusion and significant respiratory depression or coma.
  • Patients using transdermal pain patches: pain patches may influence both the amount of pain patients report as well as the level of relief they obtain from other treatments.
  • Taking any medication that might interact with one of the study medications, such as SSRI or tricyclic anti-depressants, antipsychotics, anti-malarial medications (quinidine or halofantrine), amiodarone or dronedarone, diphenhydramine, celecoxib, ranitidine, cimetidine, ritanovir, terbinafine or St. John's Wort.
  • Patients who have been previously enrolled in this same study: Patients may only be enrolled once.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. NRS Change at 60 minutes

    Between group difference in change in NRS pain scores from baseline

    Measured: 60 minutes

Secondary outcomes (3)
  1. Forego Additional Pain Medication

    Difference in proportion of patients who choose to forego additional pain medication

    Measured: 60 minutes

  2. Receive Rescue Medication

    Difference in proportion of patients who receive additional pain medication before primary outcome

    Measured: Before 60 minutes

  3. Experience Medication Side Effects

    Difference in proportion of patients who experience medication side effects grouped by GI (vomiting, nausea), dermatologic (pruritis, rash), and CNS (dizziness, drowsiness) categories.

    Measured: 120 Minutes

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Acetaminophen and Hydromorphone in people with Pain, Acute, run by Montefiore Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

NRS Change at 60 minutes (time frame: 60 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03107481, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Nov 2017; AzTrials last refreshed its copy on 1 Nov 2026.
