Glucosamine sulfate 400mg / Chondroitin sulfate 100mg capsules

It is well known that different types of exercise significantly improve physical function and relieve pain in knee osteoarthritis (KOA) patients. The aim of this study was to investigate the added effects of glucosamine or glucosamine and chondroitin supplementation in combination with an exercise program in the management of KOA. The randomized controlled trials on adding glucosamine (G) or G combined with chondroitin (C) to an exercise program in the treatment of KOA were searched in the PubMed, Cochrane Central Register of Controlled Trials, PEDro, and Web of Science online databases. The Pedro scale tool was used to assess quality of literature. A meta-analysis was performed using the Review Manager 5.4 software. In total, 6 studies (including 297 participants) were included for the final meta-analysis. According to the PEDro scale, the average quality of the studies was rated as good (mean = 8.2 (2)). The results showed that the effect of G, or G and C, in combination with exercise is not significant, as indicated by the assessed knee pain (WOMAC pain: SMD -0.18, 95% CI -0.47 to 0.11, p = 0.23; and VAS pain: SMD -0.34, 95% CI -0.85 to 0.17, p = 0.20) and physical function (SMD -0.13, 95% CI -0.95 to 0.69, p = 0.76). Adding glucosamine alone or a combination of glucosamine and chondroitin to exercise, has no effect on knee pain and physical function compared with exercise alone in KOA patients. Keywords: treatment, dietary supplement, physical activity, older adults.

Background: The lack of definitive scientific evidence sustains uncertainty about the efficacy of glucosamine and its combination therapies for knee osteoarthritis (KOA), contributing to an ongoing debate among clinical practice guidelines and healthcare practitioners. This systematic review and network meta-analysis (NMA) aimed to identify the most effective glucosamine combination therapy for KOA patients. Methods: Frequentist random-effects models were employed for this NMA, with standardized mean differences (SMDs) and 95% confidence intervals (CIs) calculated for primary outcomes. We incorporated an SMD value of 0.40 as a minimum clinically important difference (MCID) to interpret the pain outcome. Confidence in evidence was evaluated using CINeMA. Results: Thirty randomized controlled trials (RCTs) covering 5265 patients were included. Glucosamine with omega-3 (G + omega-3, SMD -2.59 [95% CI -4.42 to -0.75], moderate quality) and glucosamine with ibuprofen (G + ibuprofen, SMD -2.27 [95% CI -3.73 to -0.82], moderate quality) significantly reduced overall pain compared to placebo. Similarly, glucosamine + chondroitin sulfate + methylsulfonylmethane showed effectiveness in pain reduction (SMD -2.25 [95% CI -3.84 to -0.67], low-quality). None of the other interventions met the MCID threshold for overall pain reduction. Moreover, clustered ranking results showed that glucosamine with omega-3 interventions was more effective than others in reducing overall pain and adverse events. Conclusions: For KOA, combining glucosamine with omega-3 and ibuprofen effectively reduces pain and may lower NSAID side effects, improving treatment guidelines and decision-making for better patient care.

Background and Objective: According to international guidelines, glucosamine and chondroitin, regarded as slow-acting drugs for osteoarthritis (SYSADOAs), have been first-line treatments for knee osteoarthritis (OA); however, their efficacies remain controversial. Additionally, the efficacies of plant extract cocktails, SKI306X, and its newer formulation, SKCPT, have not been well investigated. To evaluate the effectiveness and safety of symptomatic slow-acting drugs for osteoarthritis (SYSADOAs) in patients with knee OA. Materials and Methods: Electronic databases were systematically searched to identify randomized controlled trials (RCTs) assessing the effectiveness and safety of SYSADOAs, including chondroitin sulfate, glucosamine sulfate, and SKCPT/SKI306X. The outcomes included pain relief, functional improvements, and safety profiles. The outcome measurements were compared between the treatment and control groups, including placebo and non-placebo groups, within and after 3 months of follow-up. Results: Analysis of 21 RCTs showed significantly greater improvement in pain relief in the treatment group compared with the placebo group both within (standard mean difference [SMD], 0.38; 95% confidence interval [CI], 0.18-0.57; p p = 0.023). The treatment group also showed significantly greater functional improvements regardless of follow-up. Pain and functional improvement did not differ significantly between the treatment and non-placebo groups. Regarding the safety profile, the risk ratios did not differ significantly between the treatment and control groups, including the placebo and non-placebo subgroups. Conclusions: Glucosamine, chondroitin, and SKCPT/SKI306X improved the pain and function and were non-inferior to pharmacologic drugs for up to 12 months. These findings support the clinical use of these SYSADOAs to treat knee OA. Level of Evidence: Therapeutic Level II.

Osteoarthritis is the most common musculoskeletal disorder, leading to reduced mobility and disability. Currently, in OA, basic therapy with slow-acting symptomatic drugs for the treatment of osteoarthritis (SYSADOA) is recommended, among which chondroitin sulfate (CS) and glucosamine hydrochloride (HS), as well as their combinations, have the most convincing evidence of effectiveness. The combined drugs of CS and HS include the drug ARTRA®. The purpose of this article was to provide a systematic review of the efficacy studies of the combination drug CS and HS (ARTRA®). Of the 20 publications on the study of the efficacy of ARTRA®, 6 articles with a total of 3683 patients met the inclusion criteria. In patients treated with ARTRA, both Visual Analogue Scale and Western Ontario and McMaster University Osteoarthritis Index pain relief was observed at all time points (3, 4, and 6 months). Functional capacity of patients also had positive dynamics in the intervention groups in all presented studies.

Background/objectivesGlucosamine and chondroitin are natural substances often used alone or in combination for conditions affecting the joints. Our objective was to evaluate the efficacy and safety of glucosamine and/or chondroitin supplementation in humans as well as to determine the common dosages used.MethodsA systematic review was conducted using PRISMA methodology. Searches were performed in PubMed and Web of Science and uploaded into Covidence where two independent researchers reviewed articles according to inclusion and exclusion criteria. Quality assessment was performed using the Mixed Methods Appraisal Tool (MMAT).ResultsOf the 2013 articles screened, 146 studies were included in our review, with nearly 60% being randomized controlled trials and most conducted in Europe, Asia, or the U.S. Most studies focused on osteoarthritis and joint pain, with over 90% of efficacy studies reporting positive outcomes and most safety studies indicating minimal or no adverse effects. Glucosamine and chondroitin were most commonly administered together at daily doses of 1500 mg and 1200 mg, respectively, and often compared to a placebo or celecoxib.ConclusionsOverall, the evidence suggests that glucosamine and chondroitin are generally effective and well-tolerated, particularly for managing osteoarthritis and joint pain. Consistent dosing strategies and favorable safety profiles across a diverse range of studies support their continued use in clinical practice, but further research is needed related to other disease states.

BackgroundKnee osteoarthritis (KOA) stands as a prevalent clinical condition that frequently affects individuals. A growing body of research has highlighted the potential advantages of dietary supplements, including glucosamine and chondroitin, in the management of KOA.PurposeThis study aims to ascertain the most efficacious dietary supplement for KOA, with a specific focus on reducing pain, alleviating stiffness, and enhancing joint function.MethodsWe conducted an exhaustive search of multiple databases, including PubMed, Web of Science, Embase, and the Cochrane Library, from inception to May 2023. We specifically focused on randomized controlled trials (RCTs) comparing various dietary supplements with the placebo group within the context of KOA. Assessment of outcomes among these groups relied on the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), with weighted mean differences (WMDs) and associated 95% confidence intervals (CIs) computed. Network meta-analyses were employed to compare outcomes across different supplement groups in comparison with the placebo. The surface under the cumulative ranking curve (SUCRA) was utilized to rank these supplements.ResultsOur comprehensive analysis included 22 studies with 2,777 participants in total. The outcomes from our network meta-analysis yielded the following key findings: To reduce the total WOMAC score, the top three interventions were E-OA-7, LParActin, and LcS. For reducing the WOMAC score of pain, the most effective interventions were Aflapin, NEM, and PFP. In addressing the reduction of the WOMAC score of stiffness, NEM, Aflapin, and MSM emerged as the optimal interventions. Finally, for diminishing the WOMAC score of physical function, the most effective interventions were E-OA-7, LParActin, and LcS.ConclusionIn comparison to the placebo, NEM (for stiffness), Aflapin (for pain), and E-OA-07 (for knee function and WOMAC total score) were discerned as the most effective interventions for the treatment of KOA.Clinical trial registrationhttps://www.crd.york.ac.uk/prospero/.
