Objective. To compare the efficacy of oral administration of the chondroprotector (CP) Sustagard Artro and nonsteroidal anti-inflammatory drugs (NSAIDs) in reducing lower back pain and to assess the level of blood glucose in patients taking CP. Material and methods. Sixty patients with spondylarthrosis (SA) were studied. Patients were randomized into the CP group (n=30), which received Sustagard Artro (1 sachet once a day for 6 weeks), and the NSAIDs group (n=30) treated with injectable forms of different groups of NSAIDs for 3—7 days. Pain intensity was evaluated by the numerical rating scale (NRS) and the Oswestry disability index (ODI). Results. The reduction in the severity of pain on NRS was similar in both groups: 5.73±1.74 before treatment and 1.43±0.33 after treatment in the CP group; 6.03±0.93 and 1.17±0.97 in the NSAIDs group, respectively. No significant difference in the efficacy was observed between two groups on ODI: 34.66% at baseline and 1.86% after 6 weeks in the CP group; 37.47% and 2.27% in the NSAIDs group, respectively. Changes in the level of glucose were within the upper limit of normal in the CP group. Conclusions. Oral administration of CP (Sustagard Artro, sashe) reduces pain syndrome as effectively as NSAIDs.
