Results of ELBRUS clinical non-interventional study

Abstract

Objective: non-interventional study ELBRUS (Etoricoxib in the Treatment of Back Pain) was conducted to investigate the efficacy and safety of daily administration of Rixia® (Etoricoxib) 60 mg per day in patients with chronic non-specific low back pain (CNSLBP).Patients and methods. The study included 50 patients (31 women and 19 men, mean age 54.3±16.8 years) with CNSLBP. Educational conversation, cognitive therapy, regular therapeutic exercises, identification and treatment of comorbidities were conducted. Patients received etoricoxib 60 mg once daily. Pain intensity was assessed on a 10-point numerical rating scale (NRS), pain-related disability was assessed on the Oswestry Scale (ODS), and emotional state was assessed on the Hospital Anxiety and Depression Scale (HADS).Results and discussion. The causes of CNSLBP were: in 5 (10%) patients – sacroiliac joint involvement, in 14 (28%) – lower lumbar facet joints involvement, in 3 (6%) – myofascial pain, the remaining 28 (56%) patients had a combination of several reasons. As a result of complex treatment, the intensity of pain at rest decreased on average from 4.0±2.5 to 1.4±1.3 points, while moving – from 6.6±1.9 to 2.8±1.8 points, at night – from 2.7±2 to 0.7±0.9 points according to the NRS, disability – from 39±18.9 to 19.9±14.6% according to the ODS, the severity of anxiety – from 6.5±3.9 to 3.3±2.4 points and depression from 5.0±3.7 to 3.1±2.9 points according to HADS (p<0.001). The duration of treatment was 14.14±3.6 days on average. No adverse events were observed during treatment with etoricoxib. Conclusion. The efficacy and safety of etoricoxib in the complex therapy of patients with CNSLBP was noted.
