Abstract: | Combination analgesia is often recommended for the relief of severe pain. This was a double-blind, 5-arm, parallel-group, placebo-controlled, randomised, single-dose study designed to compare the efficacy and tolerability of a novel single-tablet combination of ibuprofen and paracetamol with that of an ibuprofen/codeine combination, and a paracetamol/codeine combination, using the dental impaction pain model. Subjects with at least 3 impacted third molars and experiencing moderate to severe postoperative pain were randomised to receive: 1 or 2 tablets of a single-tablet combination of ibuprofen 200 mg/paracetamol 500 mg; 2 tablets of ibuprofen 200 mg/codeine 12.8 mg; 2 tablets of paracetamol 500 mg/codeine 15 mg; or placebo. Results for the primary endpoint, the sum of the mean scores of pain relief combined with pain intensity differences over 12 hours, demonstrated that 1 and 2 tablets of the single-tablet combination of ibuprofen/paracetamol were statistically significantly more efficacious than 2 tablets of placebo (P < 0.0001) and paracetamol/codeine (P ? 0.0001); furthermore, 2 tablets offered significantly superior pain relief to ibuprofen/codeine (P = 0.0001), and 1 tablet was found noninferior to this combination. Adverse events were uncommon during this study and treatment emergent adverse events were statistically significantly less frequent in the groups taking the ibuprofen/paracetamol combination compared with codeine combinations. In conclusion, 1 or 2 tablets of a single-tablet combination of ibuprofen 200 mg/paracetamol 500 mg provided highly effective analgesia that was comparable with, or superior to, other combination analgesics currently indicated for strong pain. |
