氨基葡萄糖和软骨素是治疗骨关节炎的先前药物选择的替代方案。本文介绍了这两种自然疗法的作用机制,药代动力学,最近的研究结果和即将进行的研究。大多数关于葡萄糖胺和软骨素背后机制的研究都是在体外或动物模型上进行的;然而,结果显示对软骨基质合成和降解之间的平衡有有利的影响。比较了三种主要形式的氨基葡萄糖的药代动力学,尽管化合物具有90%的相等口服吸收率,但氨基葡萄糖盐酸盐显示出最大的化合物纯度。硫酸软骨素是主要的临床制剂,口服吸收略低,为70%。临床试验根据两类-放射学变化和疼痛和功能的症状改善进行评价。虽然这两种药物的不良反应轻微,但必须考虑这些相对不受监管的产品的质量和标签数量。更多的人体随机对照研究需要评估这些化合物的疗效、长期效果和质量。
Glucosamine and chondroitin are alternative solutions to previous pharmaceutical options for the treatment of osteoarthritis. This article describes the mechanisms of action, pharmacokinetics, recent findings, and upcoming studies of these two natural remedies. The majority of studies on the mechanisms behind glucosamine and chondroitin have been performed in vitro or on animal models; however, the results have shown favorable effects on the balance between cartilage matrix synthesis and degradation. The pharmacokinetics of the three main forms of glucosamine were compared, and glucosamine hydrochloride displayed the greatest compound purity, despite the compounds having equal oral absorption rates of 90%. Chondroitin sulfate has been the principal clinical formulation with a slightly lower oral absorption of 70%. Clinical trials were evaluated based on two categories-radiographic changes and symptom improvement of pain and function. Although adverse effects of these two remedies were minor, the quality and labeled quantity of these relatively unregulated products must be considered. More randomized controlled studies on humans in vivo need to evaluate the efficacy, long-term effects, and quality of these compounds.
