Effect of Celecoxib and Etoricoxib on the Pharmacokinetics and Pharmacodynamics of Oral Tramadol
A Phase 1 study testing Selecoxib and Etoricoxib in people with Healthy, run by Turku University Hospital at 1 site in Finland.
Trial summary
Tramadol is an opioid analgesic, which is widely used in the treatment of acute and neuropathic pain. After oral administration, tramadol is rapidly and almost completely absorbed. Tramadol is extensively metabolised by O- and N-demethylation, which are catalysed by the liver CYP-450 enzymes. Read more about this study

About this study
Tramadol is an opioid analgesic, which is widely used in the treatment of acute and neuropathic pain. After oral administration, tramadol is rapidly and almost completely absorbed. Tramadol is extensively metabolised by O- and N-demethylation, which are catalysed by the liver CYP-450 enzymes. O-desmethyltramadol is an active metabolite and its formation is catalysed by CYP2D6. This study is aimed to investigate the possible interaction of oral tramadol with selecoxib and etoricoxib. Selecoxib is known to inhibit CYP2D6. Twelve healthy male or female adult non-smoking volunteers aged 18-40 years with body weights within ±15% of the ideal weight for height are taken into the study. Primary endpoints of the study are plasma concentrations of tramadol and its metabolites.

What is being measured
The primary outcome is the main question the study is designed to answer.
Concentration of tramadol and its metabolites in plasma
Measured: 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48 hours after administration of tramadol
Secondary outcomes (3)
Serotonin concentrations
Serotonin concentrations will be analyzed with chromatographical methods from the blood samples drawn 0, 4 and 8 hours after tramadol administration
Measured: 0, 4 and 8 hours after tramadol administration
Pharmacodynamic effects
The psychomotor effects of tramadol will be assessed with the measurement of pupil size with Cogan's pupillometer, Maddox wing test and digit symbol substitution test
Measured: 1, 2, 3, 4, 5, 6, 8, 10, 12 hours after administration of tramadol
Analgesia
The analgesic effect of tramadol will be evaluated using the cold pressor test. Briefly, the subject's hand is immersed into ice-cold water of + 4° C up to the wrist. The subject is told to keep his or her hand in the water and to report when the cold sensation becomes painful. Cold pain threshold is defined as the latency from the immersion of the hand to the subject's first report of pain. Cold pain intensity is assessed at 30 s intervals following immersion of the hand in cold water for up to 60s . A verbal numerical rating scale of 0-100 will be used.
Measured: 1, 2, 3, 4, 5, 6, 8, 10, 12 hours after the administration of tramadol

Clinical summary

Tramadol is an opioid analgesic, which is widely used in the treatment of acute and neuropathic pain. After oral administration, tramadol is rapidly and almost completely absorbed. Tramadol is extensively metabolised by O- and N-demethylation, which are catalysed by the liver CYP-450 enzymes. O-desmethyltramadol is an active metabolite and its formation is catalysed by CYP2D6. This study is aimed to investigate the possible interaction of oral tramadol with selecoxib and etoricoxib. Selecoxib is known to inhibit CYP2D6. Twelve healthy male or female adult non-smoking volunteers aged 18-40 years with body weights within ±15% of the ideal weight for height are taken into the study. Primary endpoints of the study are plasma concentrations of tramadol and its metabolites.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Selecoxib and Etoricoxib in people with Healthy, run by Turku University Hospital at 1 site in Finland.
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 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 11 Jul 2011. 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 Finland. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Concentration of tramadol and its metabolites in plasma (time frame: 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 24, 48 hours after administration of tramadol). 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 11 Jul 2011.
