An Assessment of Fentanyl Dose Requirements in Opioid-maintained Individuals
A study testing Fentanyl in people with Opioid Dependence, run by University of Adelaide at 1 site in Australia.
Trial summary
This study seeks to determine the suitable doses of fentanyl with acceptable adverse effect and safety profile in opioid-dependent patients. The investigators anticipate that a well tolerated dose of fentanyl which produces demonstrable analgesia will be found and will be related to the patient's maintenance opioid… Read more about this study

About this study
This study seeks to determine the suitable doses of fentanyl with acceptable adverse effect and safety profile in opioid-dependent patients. The investigators anticipate that a well tolerated dose of fentanyl which produces demonstrable analgesia will be found and will be related to the patient's maintenance opioid dose.
Read the detailed description
Fentanyl is a synthetic opiate with a (clinical) potency of 50 to 100 times that of morphine. Because of its high lipid solubility, fentanyl has a rapid onset of action and a relatively short duration of action. Fentanyl is one of the most widely used agents in the synthetic opioids family. Being a pure agonist with no active metabolites, it is highly suitable for use in patients with opioid tolerance. It can be used outside of an intensive-care clinical environment.
Evidence-based guidelines for clinicians on which agents to use, what doses should be considered and whether treatment doses are related to the dose and the pharmacological properties of the maintenance opioid are lacking, but needed. This study seeks to determine the suitable doses of fentanyl required in opioid-tolerant patients, which are able to overcome the tolerance and hyperalgesia while maintaining an acceptable therapeutic index. The importance of this study is that it has the potential to improve acute pain management in the opioid-tolerant population.

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

Pupillometry
The pupil diameter will be measured every 30 minutes during the infusion.
Measured: Within 2 hours after infusion starts
Saccadic eye movement
The average peak velocity of the saccadic eye movement will be measured every half an hour for 2 hours.
Measured: Within 2 hours after infusion starts

This paper test will take 3 minutes to complete and will measure the degree of withdrawal. It will be done at 15, 30 and 60 minutes post infusion.
Measured: Within 1 hour after infusion stops

The record lists 1 site in Australia. 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.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Paul E Rolan (+61882222712), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Attainment of analgesia (time frame: Within 2 hours after starting the infusion). 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 NCT01358500, which also lists 2 linked publications.
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 6 Feb 2013; AzTrials last refreshed its copy on 8 Nov 2026.
