About this study
Official title: Atomized Intranasal Ketorolac at 30 mg Versus 20 mg for the Treatment of Acute Pain in the Emergency Department: A Randomized Non-inferiority Trial
This study aims to compare the analgesic effectiveness and side effects of intranasal ketorolac at 30 mg Versus 20 mg for the Treatment of Acute moderate and severe Pain in the Emergency Department.
Read the detailed description
Pain control is one of the problems in emergency departments (EDs). Analgesics in the intranasal (IN) form have been come into interest and focus because of their ease of application and effectiveness. Recently, IN ketorolac at 30mg has been turned out to have comparable efficacy with parenteral forms. Considering the ceiling effect of the ketorolac, this trial will study whether lower dose of 20mg for pain management is equally effective as 30mg dose.
The study is a multicenter, prospective, randomized, double blind, parallel group non inferiority clinical trial conducted in three EDs. Eligible participants are adults aged 18-65 years presenting with acute moderate to severe pain [numeric rating scale (NRS)≥4]. Participants will be randomized to receive atomized IN ketorolac 20 mg or 30 mg. Primary outcome is change in pain reduction at 30 minutes post administration. Secondary outcomes include pain reduction at 15, 45, and 60 minutes, requirement for rescue analgesia (IV morphine 0.1 mg/kg available at 30), gastrointestinal and other adverse effects, and patient satisfaction.

|---|---|---|
| 30mg Intranasal Ketorolac | Active comparator | 30 mg (1cc) ketorolac will be administered intranasally using mucosal atomizer. Half dose (0.5 cc) in each nostril Receives: Drug: 30mg Intranasal Ketorolac |

What is being measured
The primary outcome is the main question the study is designed to answer.
Pain score at 30 minutes
Numerical Rating Scale (NRS) for pain, ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate worse pain (worse outcome)
Measured: 30 minutes post-administration
Secondary outcomes (7)
Pain score at 15 minutes
Numerical Rating Scale (NRS) for pain, ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate worse pain (worse outcome)
Measured: 15 minutes post-administration
Pain score at 45 minutes
Numerical Rating Scale (NRS) for pain, ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate worse pain (worse outcome)
Measured: 45 minutes post-administration
Pain score at 60 minutes
Numerical Rating Scale (NRS) for pain, ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate worse pain (worse outcome)
Measured: 60 minutes post-administration
Need for rescue analgesia
IV morphine 0.1 mg/kg will be available at 30 minutes in cases of patients request
Measured: 30 minutes post-administration
Side effects
The patients will be assessed every 15 minutes for this outcome
Measured: From the drug administration to 60 minutes afterward
Nasal irritation
Nasal irritation will be assessed using a 3-level Likert-like scale, ranging from 1 to 3, where 1 = no nasal irritation, 2 = mild nasal irritation, and 3 = severe nasal irritation. Higher scores indicate greater nasal irritation (worse outcome).
Measured: 60 minutes after the drug administration
Patient satisfaction score
Patients will be asked to rate their satisfaction using a 5-level Likert-like scale, ranging from 1 to 5, where 1 = very dissatisfied and 5 = very satisfied. Higher scores indicate greater satisfaction (better outcome).
Measured: 60 minutes after the drug administration

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing 20mg intranasal ketorolac and 30mg Intranasal Ketorolac in people with Pain and Ketorolac, run by Tehran University of Medical Sciences.
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 4 inclusion and 27 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: opening soon, as of the sponsor's last update on 16 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Hadi Mirfazaelian, MD (00982161192240, h-mirfazaelian@sina.tums.ac.ir), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain score at 30 minutes (time frame: 30 minutes post-administration). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 16 Sep 2026.
