Title: Double-blind, Randomised, Placebo and Active Controlled, Parallel Group Study to Evaluate the Analgesic Effect of a Single Oral Administration of Four Different Combination Doses of DKP.TRIS With TRAM.HCL in Comparison With the Single Agents, on Moderate to Severe Pain Following Impacted Third Mandibular Molar Tooth Extraction
Brief Summary: The purpose of this study is to evaluate the analgesic efficacy of Dexketoprofen Trometamol and Tramadol Hydrochloride given in combinations and the analgesic efficacy of each single component in comparison to placebo on moderate to severe pain following impacted third mandibular molar tooth extraction. Ibuprofen will be used as an active control to validate the pain model.
