Interventions
Drug: Placebo for Etoricoxib 60 mg
Registration Number
NCT00746720
Lead Sponsor
University of Erlangen-Nürnberg Medical School
Brief Summary

The purpose of this study is to test the hypothesis that orally administered etoricoxib (COX-2) modulates prostaglandin and cytokine synthesis in the central nervous system (CNS) and in the periphery in surgical patients and thus reduces pain and suffering.

Detailed Description

This study will be a multiple centre, double-blind, placebo-controlled, randomized, parallel group study conducted in male and female adult patients undergoing elective primary single hip arthroplasty. In part 1 of the study 12 patients will be enrolled in the study and will be administrated 120 mg Etoricoxib or placebo orally on day one post surgery. The results from part 1 should help to adjust sampling time points (for blood, cerebrospinal fluid and hip drain fluid) if necessary. In part 2 of the study 40 patients will be enrolled and should receive 120 mg etoricoxib or placebo two hours before and 24 hours after surgery.

Primary end points will be the inflammatory mediators on peripheral and central levels. After surgical manipulation we expect increased mediators on both sides. It will be investigated if the medication could reduce the mediators compared to placebo and if the effect is related to pharmacokinetic parameters.

Primary Outcome Measures
NameTimeMethod
To test the hypothesis that orally administered etoricoxib (COX-2 inhibitor) modulates prostaglandin and cytokine synthesis in the central nervous system (CNS) and in the periphery in surgical patients.within 24 hours post dosing (study part 1) and within 48 hour post dosing (study part 2)
Secondary Outcome Measures
NameTimeMethod
To determine the CSF (cerebrospinal fluid), plasma and tissue pharmacokinetics of orally administered etoricoxib.within 24 hours post dosing (study part 1) and within 48 hours post dosing (study part 2)
To correlate the prostaglandin and cytokine response to clinical outcome parameters after hip arthroplasty.within 4 days post dosing (study part 1 and 2)
To assess the safety (via clinical laboratory tests and adverse events) of a single dose of 120 mg Etoricoxib for one day (Part1) or for two days (Part2) and placebo.within 4 days post dosing (study part 1 and 2)
