Eficácia e segurança da combinação Glicosamina e Condroitina comparada a medicamentos disponíveis no SUS para o tratamento de osteoartrite: revisão rápida / Effectiveness and safety of Glucosamine and Chondroitin combination compared to drugs available in Brazilian Public Health System for the treatment of Osteoarthritis: rapid review

Tecnologia: Combinação de glicosamina e condroitina. Indicação: Tratamento de osteoartrite em adultos. Pergunta: O tratamento com a combinação de glicosamina e condroitina é mais eficaz e seguro que os demais tratamentos para osteoartrite disponíveis no SUS? Métodos: Uma revisão rápida de evidências, uma revisão de revisões sistemáticas, com levantamento bibliográfico realizado na base de dados PUBMED, utilizando estratégia estruturada de busca. A qualidade metodológica das revisões sistemáticas foi avaliada com AMSTAR-2. Resultados: Foi selecionada uma revisão sistemática, que atendiam aos critérios de inclusão. Conclusão: A combinação de glicosamina com condroitina, comparados ao placebo, mostrou ser mais eficaz para tratamento da dor e função e alcançou o segundo lugar nas alternativas terapêuticas para tratamento da dor e função

Technology: Combination of glucosamine and chondroitin. Indication: Treatment of osteoarthritis in adults. Question: Is the treatment with the combination of glucosamine and chondroitin more effective and safer than the other treatments for osteoarthritis available in the Brazilian Public Health System? Methods: A rapid review of evidence, a overview of systematic reviews, with bibliographic search done in PUBMED database, using a structured search strategy. The methodological quality of systematic reviews was assessed using AMSTAR-2. Results: A systematic review was selected, which met the inclusion criteria. Conclusion: The combination of glucosamine and chondroitin, compared to placebo, proved to be more effective for the treatment of pain and function and reached second place in therapeutic alternatives for the treatment of pain and function

Treatment of knee osteoarthritis with a new formulation of a fixed-dose combination of glucosamine sulfate and bovine chondroitin: a multicenter, randomized, single-blind, non-inferiority clinical trial

Abstract Objectives: To compare the efficacy and safety of a new formulation of a fixed dose combination of glucosamine sulfate (GS; 1500 mg) and bovine chondroitin sulfate (CS; 1200 mg) versus the reference product (RP) in patients with knee osteoarthritis (OA). Methods: In this multicenter, randomized, single-blind trial, 627 patients with knee osteoarthritis (OA)—Kellgren-Lawrence grades 2 or 3 and mean score ≥ 40 mm in the WOMAC pain subscale—were randomized to receive GS/ CS or the RP for 24 weeks. The primary efficacy endpoint was the absolute change in WOMAC pain subscale score. The secondary endpoints included the following: WOMAC total and subscale scores, overall assessment of the disease by the patient and the investigator, SF-12 score, OMERACT-OARSI response rate to the treatment, and rescue medication use. Results: Mean reductions of WOMAC pain score were - 35.1 (sd = 23.2) mm in the GS/CS group and - 36.5 (sd = 24.9) mm in the RP group. The difference between the adjusted means of both treatments confirmed the noninferiority of GS/CS versus the RP. Improvement was observed in pain, stiffness, physical function and total WOMAC score, as well as in overall OA assessment by the patient and the investigator for both groups. No improvement was observed in SF-12. The rate of OMERACT-OARSI responders was 89.4% in GS/CS group and 87.9% in the RP group. Headache and changes in glucose tolerance were the most frequent treatment-related adverse events. Conclusions: The new formulation of a fixed-dose combination of glucosamine sulfate and bovine chondroitin sulfate was non-inferior to the RP in symptomatic treatment of knee OA, with a high responder rate and good tolerability profile.
