Aim: To assess the efficacy of quick-release lornoxicam (LNX) on patient-reported acute pain after dental implant surgery. Materials and methods: The study included subjects in good general health, aged 18 to 65 and scheduled to receive a maximum of three implants in the same quadrant. Participants received either 8 mg LNX or placebo and were asked to use the medications in case of pain in the first 120 min after implant surgery. Assessment of efficacy was performed using self-assessment questionnaires for the evaluation of pain intensity and pain relief for 12 h post dosing. Patients were also asked to record the rescue analgesic number. Evaluation of patient satisfaction was assessed using a 7-point scale. Safety was evaluated by the incidence of adverse events. Results: A total of 83 (LNX/placebo, 42/41) patients who met the inclusion criteria and finished the evaluation period were included in the study. The proportion of patients experiencing postoperative pain was significantly lower in the LNX-treated group compared to the placebo group. Patients in the LNX group reported significantly higher pain relief scores than the placebo group. Twenty-nine patients in the placebo group and 6 patients in the LNX group used rescue analgesics. The number of used rescue analgesics was 1.024 ± 0.79 and 0.167 ± 0.43 in the placebo and LNX groups, respectively. The level of patient satisfaction was significantly higher in the LNX-treated patients (P = 0.007). No adverse events were reported during the study period. Conclusions: Quick-release LNX is effective in postoperative acute pain control and has a high safety profile following dental implant surgery. Schlagwörter: dental implant, lornoxicam, NSAIDs, pain
