Trial summary

Fentanyl is a widely used opioid analgesic. There are big interindividual variabilities in dose requirements of fentanyl for postoperative pain control. This study aims to reveal the genetic factors affecting the variable requirements of fentanyl during postoperative period. Read more about this study

About this study

Official title: Evaluation of Pharmacogenetic Factors Contributing to Dose Requirement of Fentanyl for Postoperative Pain Control: Genetic Polymorphisms of OPRM1, ABCB1, CYP3A4 and CYP3A5

Fentanyl is a widely used opioid analgesic. There are big interindividual variabilities in dose requirements of fentanyl for postoperative pain control. This study aims to reveal the genetic factors affecting the variable requirements of fentanyl during postoperative period.

Questions about this trial

What is this clinical trial studying?

An observational study of Pain, Postoperative, run by Inje University at 1 site in South Korea.

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 3 inclusion and 11 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 4 Jun 2013. 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 South Korea. 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?

Yes. Results are posted in the registry (first posted 27 May 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Postoperative Cumulative Fentanyl Consumption (time frame: 24 hr after surgery). 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 NCT00824772, 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 4 Jun 2013.
