[Management of postoperative pain in stomatology with ibuprofen L-arginine and naproxen]. / Trattamento del dolore postoperatorio in odontostomatologia con ibuprofene L-arginina e naprossene.

ABSTRACT

BACKGROUND: The aim of this prospective, randomized study is to compare the efficacy and safety of ibuprofen L-arginine and naproxen in the treatment of postoperative dental pain. METHODS: Seventy patients undergoing removal of impacted third molars were randomly allocated to receive 4 hours after surgery a single oral dose of either ibuprofen L-arginine 400 mg or naproxen 550 mg. Ten patients dropped out from the study because they took the study drug before the allowed time. Using a self-rating record, patients rated their pain and its relief for 1 hour after the drug administration. Remedication, if needed, and mean time of remedication were also recorded. RESULTS: A statistically significant reduction in pain scores with respect to the baseline values was recorded 5 minutes and 15 minutes after the drug administration in the ibuprofen L-arginine and in the naproxen-treated group, respectively. The summed pain intensity difference (SPID) over 60 minutes resulted significantly higher in the ibuprofen L-arginine than in the naproxen-treated group. A complete abolition of pain 60 minutes after medication was obtained in 12/28 patients (42.9%) in the ibuprofen L-arginine and in 5/32 patients (15.6%) in the naproxen-treated group, respectively (p = 0.04). Number of patients requiring remedication, mean time of remedication and drug related adverse effects did not significantly differ in the two treatment group. CONCLUSIONS: Global evaluation of the drugs by the patients showed ibuprofen more effective drug than naproxen.
