The use of ASU in the treatment of osteoarthritis Review article
Main Article Content
Abstract
Osteoarthritis (OA) is associated with chronic pain and is one of the most common causes of disability worldwide. In recent years, there has been a shift in the understanding of OA pathogenesis from “wear and tear” disease to an inflammatory condition. Avocado/soybean unsaponifiables (ASU), one of the symptomatic slow acting drugs for OA (SYSADOA), modulates the inflammatory response and may slow down cartilage degradation. Chondroprotective effects are mediated by inhibition of inflammatory factors such as interleukins (IL-1, IL-6) and tumor necrosis factor (TNF). At the clinical level, ASU reduces pain and stiffness while improving joint function, resulting in decreased dose of analgesics. ASU demonstrated efficacy in clinical trials including knee, hip and hand OA.
