title: Comparison of intravenous acetylsalicylic acid and dipyrone in postoperative pain: an interim report.
abstract: 1 In 17 gynaecological patients with postoperative pain the analgesic efficacy of intravenous lysine salicylate 1.8 g (corresponding to acetylsalicylic acid (ASA) 1.0 g) and dipyrone 1.0 g were compared in a double-blind randomized study. 2 In the ASA group, mean pain relief and pain intensity difference scores reached a maximum 30 min after drug administration and remained at this level for the next 90 minutes. 3 In the dipyrone group, these scores reached their peak 60 min after drug administration and seemed to fall off during the next hour. 4 The mean pain relief and intensity difference scores were greater following aspirin than dipyrone. However, firm conclusions cannot be drawn from the results of this small study.
