BackgroundPrevious analysis of a single data set in acute pain following third molar extraction demonstrated a strong relationship between the speed of reduction of pain intensity and overall pain relief, as well as need for additional analgesia. MethodsIndividual patient data analysis of a single randomized, double-blind trial of placebo, paracetamol 1000mg, ibuprofen sodium 400mg and ibuprofen-poloxamer 400mg following third molar extraction. Visual analogue scale pain intensity (VASPI) and other measurements were made at baseline, every 5-45min, and at 60, 90, 120, 180, 240, 300 and 360min. ResultsMost patients produced consistent VASPI results over time. For placebo and paracetamol, few patients achieved low VASPI scores and maintained them. For both ibuprofen formulations, VASPI scores fell rapidly during the first hour and were then typically maintained until later re-medication. Analysis of all patients showed that rapid VASPI reduction in the first hour was strongly correlated with good overall pain relief (high total pain relief over 0-6h), and with lesser need for additional analgesia within 6h. Results for this analysis were in very good agreement with a previous analysis, validating the relationship between fast initial pain intensity reduction and overall good pain relief in this setting. ConclusionsIn acute pain following third molar extraction, faster acting analgesic formulations provide earlier onset of pain relief, better overall pain relief and a less frequent need for additional analgesia, indicating longer lasting pain relief.
