Trial overview
The available clinical trial for Ibuprofen Arginine studied patients with moderate to severe somatic pain after dental surgery, especially after extraction of third molars (wisdom teeth).[1] The study was a Phase 3 interventional trial and it was completed with 346 enrolled participants.[1]
Study design and comparison groups
This trial was described as randomised, double-blind, placebo-controlled, and active-treatment, which means patients were assigned by chance to groups and neither patients nor researchers knew the assignment during the study.[1] The study compared an oral combination of ibuprofen (arginine) and tramadol HCl 400/37.5 mg with the active components given alone and with placebo groups.[1]
The oral treatments listed in the trial data included Espididol 400 mg granulado para solución oral sabor menta, Adolonta 100 mg/ml solución oral, placebo granules for oral solution, the fixed combination of ibuprofen (arginine)/tramadol HCl 400/37.5 mg granules for oral solution, and placebo oral solution.[1]
Who participated
The study focused on people with pain after dental extraction, and the brief summary specifically mentions third molar extraction.[1] This means the target population was adults or other eligible patients who had moderate to severe pain after this type of dental surgery, according to the study rules.[1]
What was measured
The main endpoint was SPID0-12h, which means the sum of pain intensity differences from the start of treatment until 12 hours later.[1] Pain was measured using the Visual Analogue Scale (VAS), a simple tool where patients show how strong their pain is on a line or scale.[1]
The trial aimed to see whether the combination treatment gave better pain relief than the single active ingredients used alone and than placebo.[1] In simple terms, the study asked whether the combination controlled pain better over the first 12 hours after treatment.[1]
What the trial helps answer
This study helps show whether Ibuprofen Arginine, when used in a fixed oral combination with tramadol HCl, can improve short-term pain control after dental surgery.[1] Because it included placebo and active-treatment comparisons, it can help researchers judge both how well the treatment works and how it performs against other options in a real trial setting.[1]
The current trial data do not provide results, so the main value of the record is in showing the research question, the patient group, the trial phase, and the outcome measures used.[1]
