Brief summary
The study is aimed to evaluate the analgesic efficacy of TRAM.HCl/DKP.TRIS 75mg/25mg oral fixed drug combination in comparison with TRAM.HCl /paracetamol 75mg/650mg in the treatment of moderate to severe acute pain.
Detailed description
The present phase IV study is a randomised, double-blind, placebo and active-controlled, parallel group study in moderate to severe acute pain after removal of impacted lower third molar. In this single-dose clinical trial patients are randomized to the following 3 treatment arms in a 2:2:1 ratio: * TRAM.HCL/DKP.TRIS * Paracetamol/TRAM.HCL * Placebo.

| TOTPAR6 (Total Pain Relief Over 6 Hours Post-dose) | 6 hours post-dose | TOTPAR calculated as the weighted sum of the PAR scores, measured according to a 5-point VRS (Verbal Rating Scale) from 0=no relief to 4=complete relief, over 6 hours post-dose (TOTPAR6).

| % of Patients Achieving at Least 30% of PI (Pain Intensity) Reduction Over 8 Hours Post-dose | 8 hours post-dose | Percentage of patients who achieve at least 30% of PI Reduction versus baseline Over 8 Hours Post-dose.

Recruitment details
This study was conducted in 18 centers across 5 European countries: Hungary, Italy, Poland, Spain and the United Kingdom. The clinical phase of the study started on 28th April 2016 (first screened patient) and concluded on 14th February 2017 (last patient out).
Pre-assignment details
A total of 792 patients were screened, of which 654 patients were randomized. One randomized patient was excluded from all the analysis populations, because of being younger than 18 years old. Prior to randomization, enrolled patients underwent a Screening period lasting up 2 weeks.

Outcome results
TOTPAR6 (Total Pain Relief Over 6 Hours Post-dose)
TOTPAR calculated as the weighted sum of the PAR scores, measured according to a 5-point VRS (Verbal Rating Scale) from 0=no relief to 4=complete relief, over 6 hours post-dose (TOTPAR6). The TOTPAR6 ranges from a minimum of 0 to a maximum of 24.
Time frame: 6 hours post-dose
Population: A total of 654 patients were randomized and received the study treatments, of these one underage patient, erroneously enrolled in the study, was excluded from all the analysis populations, therefore 653 patients constituted ITT population.
