Primary outcomePrimary: Sum of Pain Relief and Pain Intensity Differences From 0 to 6 Hours (SPRID 6 Hours) — 10.60; 5.87; 3.35 Units on a scale — p=0.0004
Summary
GlaxoSmithKline will be conducting this trial to compare analgesics efficacy of paracetamol 1000mg vs 500mg . The post-surgical dental pain model will be used to evaluate the analgesic efficacy of paracetamol. Each subject will be enrolled in the study for up to six weeks. The duration of the entire study will be approximately 16 weeks. Each subject will have to come to the clinic for three visits (Screening, Treatment and Follow up visits).
